Volkswagen model range. The most reliable Volkswagen gasoline engines according to owner reviews Technical characteristics and model range

Audi cars are one of the most desirable representatives of the secondary market. There are several reasons for this interest: the high durability of many models, pleasant finishes, good equipment and excellent technical data. But when choosing a used “car with rings”, you should be careful.

Firstly, low prices are often a harbinger of low mileage or hidden defects. Secondly, parts and repairs are often expensive. Even if nothing breaks, maintenance costs will be high. At the same time, with the increase in the Audi class, the cost of ownership increases like an avalanche.

If the Audi A3 is not yet so expensive to maintain, then the Audi A6 may turn out to be unaffordable. It's all about a more complex suspension, electronics and a tightly packed engine compartment.

Both petrol and diesel engines can generate unexpectedly high costs. Among gasoline units, a breakthrough occurred in 2007. Then the 1.4, 1.8 and 2.0 TFSI came under the Audi hood. At the same time, numerous troubles arose: the timing drive failed, oil wasted, pistons were destroyed. The V6 deteriorated somewhat earlier, when the fast and durable 2.4 was replaced by the 2.4 FSI.

The story in the diesel branch is no less complicated. An example of this is the successful 1.9 TDI and the failed 2.5 V6 TDI (the latest versions of which, for example, BAU have already been practically freed from the defect). Then came the unsuccessful 2.0 TDI PD with pump injectors and the decent 3.0 TDI V6. Later, the 2.0 TDI PD was replaced by an improved 2.0 TDI CR with a common rail injection system.

Gasoline engines.

1.6 8V – low operating costs.

You shouldn't expect good dynamics and efficiency from a 1.6-liter naturally aspirated petrol engine. However, the Audi A3 with 1.6 8V is the cheapest Audi to maintain. Those who love dynamic driving should stay away from cars with such an engine.

This engine can be found under the hood of the Audi A3 (1st and 2nd generation) and A4 (B5 and B6). It was also widely used in other VW Group vehicles. Only the first A3, which weighs just over a ton, drives moderately well. A4 B6 is too heavy for 1.6. Disadvantages include fuel consumption. 9 liters per 100 km seems disproportionately high for mediocre dynamics.

However, in the era of complex engines, this is the only unit that guarantees low operating costs. Among the typical malfunctions, one can only note failing ignition coils and contamination of the throttle valve. Nothing expensive. Replacing the timing belt? Installation of gas equipment? It doesn’t get any cheaper, especially when compared to engines with direct injection and timing chain drive.

The motor uses an aluminum body and head. The crankshaft rests on five bearings, and multipoint (distributed) injection is responsible for fuel supply. The camshaft is located in the cylinder head.

Advantages:

Simple design;

Cheap repairs;

Tolerates the introduction of HBO well;

Low cost of the car.

Flaws:

Poor dynamics (overtaking is difficult, especially in the case of the A4);

Relatively high fuel consumption.

1.8 Turbo – powerful and reliable.

The 1.8-liter turbocharged engine is still worthy of attention. It is durable and fairly cheap to repair. The possibility of tuning is also appreciated.

The 1.8 T provides decent performance and reasonable fuel consumption. This is one of the first turbo engines to become widespread. It can be found not only in Audi, but also in Volkswagen, Skoda and Seat. The engine was even used in industry.

The unit has a cast iron block, a forged steel crankshaft and an aluminum cylinder head with 20 valves (3 inlet and 2 exhaust per cylinder). A toothed belt is used to drive one camshaft, and the second shaft is connected to the first by a short chain. The KKK turbine has no moving blades (constant geometry), and fuel injection is distributed. The block in a “dry state” weighs about 150 kg.

It soon became clear that the 1.8 Turbo has very great potential. It was produced as standard at 240 hp, and during the tuning process it can easily withstand boost up to 300 hp. Of course, in the case of a tuning unit, you should increase your vigilance, since it may already be worn out.

And yet, more often the turbo engine was not used for sports trips. Under normal conditions, a car with such an engine consumes from 9 to 14 liters per 100 km.

With age, a number of shortcomings have emerged (timing timing belt and thermostat), but their elimination does not require large expenses.

Advantages:

Good compromise between performance and fuel consumption;

Availability and availability of spare parts;

Wide choice on the market.

Flaws:

Several unpleasant typical defects in old cars with high mileage (oil consumption and timing faults).

Application examples:

Audi A3 I (8L);

Audi TT I (8N);

Audi A4 B5, B6 and B7.

2.4 V6 - only until 2005.

Despite the emergence of increasingly powerful in-line turbo-fours, Audi fans still prefer naturally aspirated petrol V6s, especially in early versions. Of course, you shouldn’t count on low fuel consumption - at least 10 liters per 100 km. In the city you will have to reckon with even 20 liters. But the trip will seem pleasant.

It is necessary to clearly distinguish between two generations of the 2.4-liter engine. They have the same volume and dimensions, but modernization took place in 2004. Before the update, the block was cast iron, and the head had 30 valves (5 per cylinder). Afterwards, the block became aluminum, the number of valves was reduced to 24, direct injection and a timing chain appeared.

The latest innovations have let us down. Due to the direct injection system (FSI), carbon deposits accumulated on the valves after only a few tens of thousands of kilometers. There were problems with the timing chain tensioner and a small strainer in the lubrication system. Completely ignoring the noise often resulted in chain jumping and serious damage. In 2008, Audi eliminated the vulnerability of the timing drive, but the engine could not withstand the pressure of 4-cylinder turbo engines.

Advantages:

Good elasticity;

High reliability (only before updating);

Versions with distributed injection easily tolerate the installation of gas equipment.

Flaws:

Limited sense of installing HBO in the updated version of FSI;

Expensive timing faults (FSI);

Quite high fuel consumption.

Application examples:

Audi A4 II (B6);

Audi A6 C5 and C6.

Diesel engines.

1.9 TDI – durable and economical.

This is the most recognizable diesel engine of recent years. Even an older Audi with a 1.9 TDI is worth a look - robust construction and inexpensive repairs.

1.9 TDI is a legend engine. Produced since 1991 and modernized many times. It has found its way into many other VW Group vehicles.

The 90-horsepower version with a distribution-type injection pump is recognized as the most reliable and cheapest to operate and repair. The engine has a simple design, a constant geometry turbine and a single-mass flywheel.

Yes, minor problems happen sometimes. For example, with an exhaust gas recirculation valve, an air flow meter and a fuel pump. But for the most part, malfunctions are caused not by design flaws or poor quality, but by considerable age and high mileage.

The younger and more powerful versions of the 1.9 TDI have introduced more solutions that can create problems. We are talking about a variable geometry turbine, a dual-mass flywheel, pump injectors and a DPF. However, even these versions appear in a more favorable light against the background of diesel engines.

The exception is the 2006-2008 BXE version, which fell, for example, under the hood of the second generation Audi A3. There are many cases of bearings turning after 120-150 thousand km.

Advantages:

Simple design;

Good endurance;

Low fuel consumption.

Flaws:

There are many worn-out examples (the engine was installed until 2009, and since 2004 it has been gradually replaced by a 2-liter turbodiesel);

Poor work culture: noise and vibration, especially after starting a cold engine.

Application examples:

Audi A3 I (8L) and II (8P);

Audi A4 B6 and B7;

Audi A6 C4 and C5.

2.0 TDI CR – everything is finally good.

A 2-liter diesel engine is the main unit for most Audi models. Since 2007, he began to use the Common Rail injection system.

The design flaws of the 2.0 TDI with unit injectors prompted Volkswagen engineers to thoroughly modernize it. Changing the way we eat is the most important new thing. The pistons were also updated, problems with the oil pump drive were eliminated, a new cylinder head and camshafts were installed. As a result, engine durability was significantly improved, but disadvantages also appeared.

When buying an Audi with a 2.0 TDI engine, you should check the car's history. Often, these were cheap and economical versions purchased for commercial or corporate garages. They have huge miles and have not always been well maintained.

Typical faults affect the dual-mass flywheel and turbocharger. Piezoelectric injectors fail here no more often than their competitors. Fortunately, they can be restored. As part of the service campaign, the manufacturer replaced the high-pressure lines.

Advantages:

Good performance with acceptable fuel consumption;

Good durability (especially compared to the 2.0 TDI PD);

Wide variety of versions.

Flaws:

Expensive maintenance (complex design and expensive spare parts);

Significant mileage of many copies, despite their relatively young age.

Application examples:

Audi A4 III (B8);

Audi A6 III (C6).

3.0 TDI – for the demanding.

High performance and dynamics are not the only advantages of the 3.0 TDI. Therefore, many choose it with pleasure, even despite the rather high maintenance costs.

The 3-liter turbodiesel was designed to correct the bad reputation of Audi V6 diesels, spoiled by the 2.5 TDI V6. The 3.0 TDI earns respect not only for its performance, but also for its durability. The block, cylinder head and crank mechanism turned out to be very strong. There are 4 valves and one piezoelectric injector for each cylinder.

The problems mainly concern equipment. The most common problem is the timing drive, the replacement cost of which is very expensive. Before 2011, 4 chains were used, and after - two. The drive chain is located on the gearbox side. To replace it, you have to remove the engine.

The flap in the intake manifold (repair kits are available for sale) and the DPF are not free from shortcomings. The engine is constantly being improved, and in later versions malfunctions are much less common.

Advantages:

High work culture;

Good performance;

Low fuel consumption;

Good service life for many engine parts.

Flaws:

Expensive in troubleshooting timing belt, intake manifold and DPF faults;

Many examples on the market have high mileage and questionable technical condition.

Application examples:

Audi A5 I (8T/8F);

Audi Q7 I (4L);

Audi A8 II (D3).

Risky choice!

Audi's range includes engines that are great in theory but painfully disappointing in practice. In particular, the first generation 1.4 TFSI with a problematic timing chain drive should be mentioned. Currently, a more reliable version with a timing belt drive is used.

The 1.8 and 2.0 TFSI engines with the code designation “EA888” are tempting with their high output. However, they suffer from high engine oil consumption. There are also problems with the turbine, camshafts and electronics.

There are also black sheep among diesel units. For example, the Audi A2 was equipped with a 1.4 TDI with pump injectors. The problem is the appearance of crankshaft play, the elimination of which is not economically feasible. The 2.0 TDI PD is known for its cracking cylinder head and poor equipment durability. The 2.5 TDI V6 is plagued by numerous mistakes with the timing belt, as well as with the lubrication and power system.

Conclusion.

Once upon a time, buying an Audi was easier - the engines guaranteed quiet operation. Nowadays you need to pay attention to the version. Along with truly successful engines, they also used those for which the designers should be ashamed. At the same time, even a fairly reliable modern engine will be expensive to maintain and maintain.

Volkswagen engines - diesel, contract, their cooling system, diagnostics, videos on the topic

The Volkswagen concern produces a fairly wide range of power units, which includes spark-ignition gasoline engines and compression-ignition diesel engines. The concern installs its own developments on both passenger cars and trucks.

Review of Volkswagen engines

The Volkswagen concern, founded in Berlin on May 28, 1937, declared as a priority the production of affordable cars with optimal technical characteristics. The machines had to meet the following requirements:

the highest possible level of security;
reliable engine;
economical use of fuel;
acceptable comfort;
salon for four people;
minimal impact on the environment;
decent quality of interior trim.

In other words, the concern had to produce budget cars with a powerful and economical engine.

Every VW Beetle owner imagined himself in a car with a powerful engine

Evolution of Volkswagen engines

All engines produced by the Volkswagen Group are tested at the accredited testing center Deutsches Institut für Normung. The units have an efficient direct injection system and an environmentally friendly exhaust system. The concern has received several innovation awards for its engines.

All power units have been developed in accordance with Volkswagen environmental standards

Throughout its history, the concern has tried to make the engine more economical. The result of these studies was a unit that consumes 3 liters of fuel per 100 km. It was a 1.2 liter three-cylinder diesel engine with an aluminum block, injection system, turbocharger and supply air cooling. Reducing the number of cylinders had a slight effect on the dynamic characteristics of the engine. With minimal fuel consumption, the unit showed decent power due to:

reducing engine weight;
reducing friction between contacting units and parts;
increasing the combustion efficiency of the fuel-air mixture;
modernization of the injection system with an exhaust gas turbocharger.

The family of light turbocharged gasoline engines defines a new direction for the concern's development

First Volkswagen engines

In 1938, the VW Type 1 was released, powered by the revolutionary air-cooled F4 four-cylinder engine. The unit had a volume of 1.131 liters and a power of 34 liters. With. In the process of evolution, engine volume increased from 1.2 to 1.6 liters. The latest model was the perfect combination of performance, efficiency and reliability. Due to the design of the carburetor, optimal proportions were observed when forming the combustible mixture. The 1.6 liter engine marked the beginning of a line of engines for cargo and passenger vans.

The production capacity of the Volkswagen engine plant in Kaluga allows the production of up to 5,000 engines per year

Volkswagen engine specifications

The standard Volkswagen engine is a four-cylinder unit with an overhead camshaft and water cooling. Typically, the cylinder block, its head and pistons are made of aluminum alloy, and the crankshaft with three support bearings is made of forged stamped steel.

Volkswagen engines have the following technical characteristics:

fuel consumed - gasoline or diesel fuel;
cooling system - air or liquid;
type of cylinder arrangement - in-line, V-shaped or VR;
volume - from 1 to 5 l;
power - from 25 to 420 hp. With.;
fuel consumption - from 3 to 10 liters per 100 km;
number of cylinders - from 3 to 10;
piston diameter - up to 81 mm;
number of working cycles - 2 or 4;
type of mixture ignition - spark ignition or compression ignition;
number of camshafts - 1, 2 or 4;
the number of valves in the combustion chamber is 2 or 4.

TSI petrol engines are the ideal combination of performance and economy. Even at low speeds they deliver maximum torque, and the carefully calibrated combination of piston movement, turbocharging and direct injection ensures even fuel delivery.

The fuel injector sprays the fuel mixture under high pressure

Volkswagen gasoline engines are characterized by:

formation of the fuel mixture in the intake manifold or directly in the combustion chamber;
ignition of the mixture from spark plugs;
uniform combustion of the mixture;
quantitative adjustment of the mixture;
four-stroke principle of operation with two revolutions of the crankshaft at an angle of 720°.

Volkswagen TDI diesel engines with turbocharging and direct fuel injection are characterized by:

efficiency;
high traction power;
productivity;
reliability in operation.

Optimal viscosity of diesel fuel ensures good mixture formation in the combustion chamber

The operation of a Volkswagen diesel engine is characterized by the following points:

formation of a mixture of fuel and air in the combustion chamber;
self-ignition of fuel from heated compressed air;
high compression ratio;
high-quality preparation of the mixture;
The principle of operation of a four-stroke engine is two revolutions of the crankshaft.

The designers were able to compactly place the oversized engine in the engine compartment

The advantages of Volkswagen gasoline engines are:

low weight-to-power ratio (kg/kW);
wide range of uses;
good dynamics;
low cost;
all-season;
ease of maintenance.

However, such units also have disadvantages. First of all this:

relatively high fuel consumption;
weak traction at low speeds;
increased consumption when loading the cabin;
fire hazard of fuel.

Three-quarters of the 2013 Volkswagen Jettas are equipped with a two-liter turbodiesel engine.

The advantages of engines running on diesel fuel include:

low fuel consumption;
high torque;
lack of spark plugs;
good handling at low speeds;
good throttle response in high gears.

The disadvantages of diesel engines are:

high requirements for fuel quality;
seasonality of fuel (problematic starting in cold weather);
quite expensive maintenance;
the need to strictly adhere to the frequency of oil and filter changes;
high price.

Volkswagen engines for trucks

Vehicles carrying heavy loads typically operate at low speeds and require increased engine power. The best option for them is a flexible diesel engine with an optimal ratio of its power and vehicle weight. The higher the elasticity of the engine, the less time it takes to accelerate. This is especially true in city conditions, where diesel units are much more efficient than gasoline ones.

The VW Crafter engine is a combination of practicality, functionality and efficiency

Cylinder arrangement in Volkswagen engines

Depending on the location of the cylinders there are:

in-line engines;
V-engines;
VR engines.

Each variety has its own advantages and disadvantages.

In-line engine

A conventional piston engine consists of a series of cylinders arranged one behind the other. It is most often installed on cars and trucks and usually consists of four cylinders, the counting of which starts from the flywheel.

The four-cylinder engine is most often installed in cars and trucks.

The advantages of a four-stroke engine with a longitudinally symmetrical crankshaft are usually noted as good dynamics and relatively low cost. The disadvantage of such a unit is the increased requirements for space in the engine compartment required to accommodate a block of four cylinders.

V-engine

A V-twin engine consists of several cylinders located at an angle to each other. The tilt angle can reach 180°. Due to this, a larger number of cylinders can be placed in a limited space. All engines with eight or more cylinders are typically a V-twin model (V6, V8 or V12). V4 units, compared to their in-line counterparts, have a better weight-to-power ratio, but are more expensive to manufacture.

A V-twin engine consists of several cylinders located at an angle to each other

Compared to an in-line engine, the V-twin unit is more compact and lightweight. So, the V12 is only slightly longer than the six-cylinder in-line engine. The disadvantage is its more complex design, certain difficulties when balancing, a high level of vibration and the need to duplicate some components.

Video: operation of a V-twin engine with 8 cylinders

VR engine

The VR engine, developed by the concern, is a symbiosis of a V-engine with an extremely small camber angle (15°) and an in-line unit. Its six cylinders are located at an angle of 15°. This differs from traditional V-engines, in which this angle is 60° or 90°. The pistons are located in the block in a checkerboard pattern. This design allows you to combine the multiplicity of a V-twin engine with the small width of an in-line engine and significantly saves space in the engine compartment.

VR engine is a combination of V-twin and in-line engine

The VR engine also has a number of disadvantages:

a large angle of inclination of the connecting rods leads to high radial loads on the pistons;
the uneven length of the intake and exhaust channels affects the air supply and exhaust gas removal;
Manufacturing a cylinder head is quite expensive.

Characteristics of engines produced by Volkswagen AG

The Volkswagen concern produces both gasoline and diesel engines.

Volkswagen petrol engines

In the evolution of Volkswagen gasoline engines, several main models can be distinguished.

Table: technical characteristics of Volkswagen gasoline engines

In the table, the engines are located according to the letter code. Engines for the VW Beetle and VW Transporter produced before 1965 did not have a letter code. They are indicated in the table by code 1.

Volkswagen diesel engines

The main representatives of the family of diesel engines produced by Volkswagen are the following units.

Video: Volkswagen W8 engine operation

Factories producing engines for Volkswagen cars

The Volkswagen Group is the largest automaker in the world. The number of employees is 370 thousand people who work at 61 factories in 15 European countries, North and South America, Asia and Africa. Up to 26,600 cars are produced annually, sold in 150 countries. The main production centers for Volkswagen powertrains are:

Contract engines

Any engine has a limited service life. After this resource expires, the car owner can:

make a major overhaul of the original engine;
purchase under contract in Europe or America and install a used engine.

The contract motor fully complies with the technical requirements and is a working unit dismantled from a similar car.

All contract engines undergo pre-sale inspection. Suppliers usually adjust all systems, do a test run and guarantee uninterrupted operation and a long service life. In addition to contract engines, technical documents, attachments and installation elements are included.

Overhauling a car engine is not always advisable. Especially if this model has already been discontinued.

So, a friend of mine owned an original Volkswagen Golf 1.4 with a manual transmission from 1994. The car was used all year round and at any opportunity. Sometimes it was loaded to the limit. The old car had difficulty making it up hills with a not-so-new engine. The car, although compact, is quite roomy. Over the five years of ownership, I changed the clutch basket and release bearing. I perceived timing belts and rollers as consumables. I planned to change the pistons and do a major overhaul of the engine due to oil consumption and low thrust. But on one of the trips I didn’t keep track of the temperature and overheated the engine so much that the head turned. Repairs amounted to almost 80 percent of the car's cost. This is a high price for a used car, not counting the time spent on repairs, searching for original parts or identical analogues. Back then we had no idea about the possibility of replacing the engine with a complete set. Now we wouldn’t even think twice about it.

The advantages of an engine purchased under a contract are:

factory quality;
work on high-quality fuel;
slight wear;
long service life;
use of high-quality lubricants;
caring attitude from the former owners;
strict compliance with maintenance standards;
dealer service;
low cost compared to a new unit.

The disadvantages of such engines include:

high mileage of foreign cars;
inability to check service life;
no guarantee that the former owner will comply with the manufacturer’s recommendations.

You should not purchase a power unit older than seven years. This is true for diesel engines.

Volkswagen engine life and manufacturer's warranties

Determining the degree of engine wear is quite difficult, since it depends on:

resource regulated by the manufacturer;
operating conditions;
vehicle load;
driving style.

Volkswagen guarantees that every part and component of the car meets the standards. This warranty is valid for a year or 20 thousand km (whichever occurs first) from the date of purchase for individual parts and for 4 years or 100 thousand km for the entire vehicle.

Lack of proper attention to the engine will accelerate its wear.

A reliable mechanism does not cause trouble with increased wear of parts when changing engine oil regularly.

The warranty becomes void in cases caused by:

misuse;
negligence during operation;
changes and modifications of components and assemblies;
improperly carried out repairs;
incorrect adjustment of individual components;
intentional damage to parts;
using parts and consumables that do not correspond to this model;
use of vehicles for competitive and off-road purposes;
failure to comply with recommended maintenance intervals and operating requirements;
collision with objects;
vandalism of others;
environmental damage;
floods;
accidents;
fire.

When purchasing a new car, to extend engine life, experts recommend paying attention to the following points:

The first thousand kilometers of a new car should not be driven at high speeds. The crankshaft rotation speed should not exceed 75% of the maximum possible value. Otherwise, oil consumption will increase and wear on the inner surface of the cylinders will begin. This can significantly reduce the resource of the power unit.
The engine should be warmed up before driving. This condition is especially important for turbo engines and diesel engines.
In new diesel engines, the oil level should be checked at every refueling.
Volkswagen's recommended engine maintenance intervals must be strictly followed.

Self-diagnosis of the engine

In a modern car, the engine control unit controls the operation of sensors and main components. Possible problems are indicated by warning lights in the instrument cluster - for example, the Check Engine indicator. In addition, through the standard OBD-II port, you can connect diagnostic equipment and obtain detailed information about the operation of individual systems by reading fault codes.

Self-diagnosis allows you to avoid additional costs when visiting a car service center

Living in rural areas, you do not always have the time and opportunity to visit a service center. But you shouldn’t put up with the malfunction either, because later there will be more problems. So, the diagnostic scanner helped me out when identifying a faulty knock sensor with code P0326 “Signal out of acceptable range.” In addition, the adapter helped to independently detect the problem area with almost worn out generator brushes. Code P0562 indicated a low voltage level on the on-board network. The solution to the problem was to replace the “tablet” with a new copy. Using the scanner even in error reading mode made it possible to restore the original state of the engine's key parts. And sometimes it was enough to reset the system errors of the on-board computer when a malfunction was detected in order to calmly hit the road.

Necessary diagnostic tools

To carry out computer diagnostics you will need:

diagnostic device corresponding to the vehicle's electronic system;
computer or smartphone to decrypt the information received.

Through the standard OBD-II port, you can connect a diagnostic adapter and obtain detailed information about the operation of individual vehicle components

Volkswagen engine cooling system

The smooth operation of Volkswagen engines is largely determined by the efficiency and reliability of the cooling system, which is a closed loop connecting the power unit, radiator and pipelines. Coolant circulates through this circuit. Cooling of the heated liquid occurs in the radiator. The basis of the coolant is ethylene glycol, which is stable over a wide temperature range. The manufacturer recommends using only certain brands of coolant.

Engine coolant is usually colored, making any leaks easy to spot.

The engine cooling system is a closed circuit through which antifreeze is forced to circulate: 1 - radiator; 2 - pump; 3 - fan; 4 - thermostat; 5 - interior heater; 6 - interior heater valve; 7 - engine; 8 - direction of air flow

The water pump provides forced coolant circulation through the cooling circuit and is driven by a belt. The Volkswagen engine cooling system piping consists of hoses, a radiator and an expansion tank. Temperature control devices include sensors, a thermostat, a radiator and expansion tank cap, and a fan. All these elements function independently of the power unit. Temperature control allows you to regulate engine performance and exhaust gas composition.

Cooling system malfunctions

Most cooling system problems are the result of lack of proper maintenance of its elements and untimely replacement of coolant. The radiator and pipes are subject to wear, reducing cooling efficiency.

The main signs of malfunction are small spots of coolant under the car after parking overnight and a strong smell of the coolant when driving.

The most common problems that occur in the cooling system are:

low coolant level, leading to the appearance of air pockets, overheating and accelerated corrosion of exposed metal surfaces;
use of low quality coolant or a type not recommended by the manufacturer;
leaking or clogging of the radiator and expansion tank;
water remaining in the system after flushing it;
damage to the water pump drive belt;
coolant leak.

The location of the leak can be determined by the nature of the liquid spreading

The cooling system is not something to be trifled with, so it is worth checking the fluid level periodically.

If the engine overheats significantly, the cylinder head may become deformed and the effectiveness of the sealing gasket will decrease.

Trouble-shooting

You can keep your cooling system in working order using the following simple procedures:

daily inspection of the system for coolant leaks;
control of coolant composition, preventing water from entering the system;
complete flushing of the system after draining the old coolant;
periodically cleaning the radiator from leaves, debris and dirt;
periodically check the tension and condition of the pump drive belt.

Video: Fixing a coolant leak on a VW Jetta

Maintenance of the cooling system involves performing the following actions:

periodic cleaning of the engine compartment;
replacing the coolant every five years;
replacing hoses every two years;
replacing the thermostat at high engine temperatures;
tension adjustment and timely replacement of the water pump belt;
replacing the pump when the first signs of a malfunction appear;
checking and replacing the cooling fan and temperature sensors when the engine temperature slowly drops.

It is obvious that trouble-free operation of the cooling system is only possible if other systems and components of Volkswagen vehicles operate correctly.

Thus, the range of Volkswagen engines is quite wide. Each potential car owner can choose a power unit in accordance with his wishes, financial capabilities and operating conditions of the car.

Top 10 most reliable engines - DRIVE2

Fiat 1.2 / 1.4 8V "FIRE".

Production: from 1993 - 1.2 l, from 2003 - 1.4 l.

Application: Fiat Punto/Grande Punto/Punto Evo, Fiat 500, Fiat Panda, Fiat Idea, Fiat Palio, Ford Ka (2nd generation), Fiat Linea, Lancia Musa, Lancia Y.

Fiat engines of the FIRE series (Fully Integrated Robotised Engine - an engine completely assembled by robots) are already more than 30 years old. The range of power units covers a wide range of engines with a displacement from 769 cm3 to 1368 cm3, and 8-valve versions were later supplemented with 16-valve ones. Two 8-valve units without hydraulic pushers are worthy of attention.

In general, all versions of engines with an 8-valve head, regardless of displacement, turned out to be very durable. The simple design showed high wear resistance even in small engines (for example, 1.1). Outdated 8-valve versions, after a timing belt rupture, will not require major repairs, which is inevitable for more modern modifications that have a higher compression ratio and comply with Euro-5 standards.

FIRE engines have always been characterized by “plasticity” of character. Incredibly, two absolutely identical engines behaved completely differently after running in. So with calm drivers he behaved lazily, and with temperamental drivers he behaved more lively.

Regular maintenance includes replacing the timing belt, spark plugs and a reasonable oil change interval (in Europe it is a maximum of 15,000 km). These engines are absolutely reliable, only occasionally causing minor oil leaks.

Ford 1.3 8V Duratec "Rocam".

Production: 2001-2008

Application: Ford Ka (1st generation), Ford Fiesta VI.

The engine is similar in design and parameters to the older 1.3 OHV. It has a cast iron block, timing chain and hydraulic tappets. The power unit is rather lazy, but absolutely reliable. It has good traction at low revs and requires minimal operating costs. The engine was assembled in Brazil and South Africa (South Africa). The abbreviation Rocam means shaft with roller bearings.

Along with the ancient OHC "Pinto" unit (used in the Ford Sierra, for example), this is one of the most reliable engines to ever sit under the hood of a Ford. Larger Rocams with a displacement of 1.6 liters are much less common. They were used mainly in the “charged” Ford SportKa and Ford StreetKa.

Honda 2.2 i-DTEC.

Production: 2008-2015.

Application: Honda Accord 8th generation, Honda CR-V 3rd generation, Honda Civic – 9th generation.

In fact, you could list 98% of Honda's petrol units here and no one would object. But much more interesting is the fact that the Japanese diesel engine turned out to be very reliable. And this despite the fact that its design uses all the most vulnerable elements of modern diesel engines, which the best competitors cannot cope with.

The use of a single-row timing chain is completely counterproductive, not to mention the thermally unstable aluminum block with thin, dry steel cylinder inserts (complicating heat dissipation), as any BMW N47 diesel connoisseur will tell you.

In 2.2 i-DTEC, such a set works properly for a long time. Even piezoelectric injectors, a turbocharger (has water-cooled bearings) and an electrically controlled EGR valve do not cause problems. The typically carbon-encrusted swirl flaps in the intake manifold were replaced with a bypass valve at the entrance to the split intake tract, and the EGR was “plugged in” behind it.

The only known drawback is the failure of the DPF differential pressure sensor.

Mercedes M266 (1.5 / 1.7 / 2.0).

Production: 2004-2012.

Application: Mercedes A-Class (W/C 169), Mercedes B-Class (T 245).

Durable and reliable diesel engines from OM601 to OM606 are known from the legendary W124. But they have long been outdated. However, even among newer units you can find a durable motor. This is M266. The 4-cylinder petrol engine is an evolution of the previous M166, known from the first A-Class and Vaneo.

The engine received a specific design, since it had to be placed at a large angle in a cramped engine compartment. The engineers relied on simplicity: only one timing chain and an 8-valve timing mechanism.

The mechanical part is very reliable. Injector malfunctions are very rare (somewhat surprising for a gasoline engine with indirect injection). But in most cases, the defect appeared during the warranty period.

All three versions of the motor are very durable. The presence of turbocharging for A200 Turbo modifications theoretically increases the likelihood of malfunctions, but in reality nothing like this happens. The disadvantages include slightly increased fuel consumption, but this is due to the insufficiently good aerodynamics of the body.

Mitsubishi 1.3 / 1.5 / 1.6 MIVEC (4A9 series).

Production: since 2004.

Application: Mitsubishi Colt, Mitsubishi Lancer, Mitsubishi ASX, Smart ForFour, Citroën C4 Aircross.

Almost all Mitsubishi gasoline engines are very reliable, so choosing the best one is not easy. One of the most common is the 4-cylinder unit of the 4A9 series. It was created as a Mitsubishi/Daimler-Chrysler collaboration and is one of the most reliable engines on the market today.

The 4A9 is made entirely of aluminum, has a 16-valve DOHC gas distribution system, a variable intake valve timing system with electronic control MIVEC (some versions of the 1.3-liter engine do not have it). Although the engine is more than 10 years old, there are no known problems. Cars with such engines come to the service center only for maintenance - replacement, oil, filters and spark plugs.

4A9 is only atmospheric. The turbocharged Colt CZT/Ralliart models use a completely different Mitsubishi "Orion" series engine. The Citroen C4 Aircross inherits the engine from its technical twin, the Mitsubishi ASX 1.6 MIVEC, but markets it under the simple name 1.6 i, and in some markets even under the absolutely amazing 1.6 VTi.

PSA 1.4 HDi 8V (DV4).

Production: since 2001.

Application: Citroen C1, C2 Citroen, Citroen C3, Citroen Nemo, Peugeot 107, Peugeot 1007, Peugeot 206, Peugeot 207, Peugeot Bipper, Toyota Aygo, Ford Fiesta, Ford Fusion, Mazda 2.

The little 1.4 HDi can be seen as the successor to the legendary XUD7/XUD9. Even though, on paper, the 1.4 HDi was created in collaboration with Ford (like the larger 1.6 HDi). In fact, this is a completely French design, which turned out to be very successful.

Like Honda, the French were able to create a durable aluminum block with dry inserts. A timing belt can last 240,000 km or 10 years. A simple turbocharger will last forever. The common rail injection system from Siemens has proven itself from the very beginning. Mazda, Ford and some PSA models have recently mentioned the Bosch injection system.

Initiates know that there is also a 16-valve version with a return of 90 hp. for more powerful options - Citroen C3 1.4 HDi and Suzuki Liana 1.4 DDiS. With its leaky 16-valve head, variable geometry turbocharger and Delphi injection system, this engine will never compare to a simple 8-valve version in terms of reliability.

Subaru 3.0 / 3.6 R6 (EZ30 / EZ36).

Production: since 2000.

Application: Subaru Legacy, Subaru Outback, Subaru Tribeca.

Of all the famous boxer engines of Subaru, the most reliable are the naturally aspirated six-cylinder EZ series, known for the Outback, Legacy 3.0R and the Tribeca crossover. The first versions of the 3-liter engines for the Outback H6 (219 hp until 2002) still had a mechanical throttle control drive and an aluminum intake manifold. Later modifications (245 hp), despite more complex technologies (among others, a system for adjusting the lift height and phases of the intake valves, and in the 3.6 also the exhaust valves), did not become more “vulnerable”.

The engine has so-called wet cylinder liners and a durable timing chain. The only real drawback is the relatively high level of fuel consumption (especially in the Legacy 3.0 Spec B, equipped with a sports manual transmission with a short-throw gear selector) and minor difficulties during maintenance (for example, to replace spark plugs due to poor accessibility to the “horizontally” located engine).

Suzuki 1.3/1.5/1.6 DOHC "M".

Production: since 2000.

Application: Suzuki Jimny, Suzuki Swift, Suzuki Ignis, Suzuki SX4, Suzuki Liana, Suzuki Grand Vitara (1.6), Fiat Sedici (1.6), Subaru Justy III.

The M series engines include small capacity engines 1.3, 1.5, 1.6 and 1.8. The latter is intended exclusively for the Australian market. On the European continent, the power unit is found in almost all small and medium-sized Suzuki models that appeared at the turn of the millennium, and in the Fiat Sedici 1.6, which is a copy of the Suzuki SX4. The mechanical part of the engine is very reliable and durable. Even the VVT variable valve timing system, used by most engine modifications, does not cause any complaints. It is not present only in the 1.3-liter version intended for Ignis and Jimny until 2005, and the old 1.5 modifications for SX4.

The timing chain drive is reliable. Minor deficiencies include small oil leaks through the crankshaft oil seal. More serious malfunctions practically never occur.

Toyota 1.5 1NZ-FXE Hybrid.

Production: since 1997.

Application: Toyota Prius I, Toyota Prius II, Toyota Yaris III Hybrid.

As in the case of Honda, almost all Toyota engines could be included in this review, but we will focus on the hybrid, which most motorists still perceive with skepticism. And this despite the fact that this power unit has unprecedented reliability. A simple high compression gasoline engine running on the Atkinson cycle, a permanent magnet synchronous electric motor and nothing more.

There is no gearbox in the classical sense, and therefore problems with this device disappear. Instead, a planetary gearbox with two inputs and one output is used. The gear ratio changes depending on the difference in the rotation speeds of both engines.

What scares me the most is the expensive battery. But so far none of the owners have changed it. European competitors cannot compete with the phenomenal Japanese reliability.

Volkswagen 1.9 SDI/TDI.

Production: 1991-2006 (in some markets until 2010).

Application: Audi 80 B4, Audi A4 (1st generation), Audi A3 (1st generation), Audi 100/A6 (C4), Audi A6 (C5), Seat Alhambra, Seat Ibiza, Seat Cordoba, Seat Inca, Seat León, Seat Toledo, VW Caddy, VW Polo, VW Golf, VW Vento, VW Bora, VW Passat, VW Sharan, VW Transporter, Ford Galaxy (1st generation), Škoda Fabia and Škoda Octavia (1st generation).

Without a doubt, this is one of the most famous, but perhaps the most controversial engines on our list. The SDI/TDI engines are based on the old 1.9 D/TD. They received direct injection, the thermal load on the cylinder head was reduced and a Bosch rotary pump was installed, although it was sensitive to fuel quality.

The reliability and durability, especially of the simple naturally aspirated 1.9 SDI versions, deserves respect. The engine is capable of traveling more than one million kilometers without major investments. We do not take into account the frequently mentioned problems with the mass air flow sensor.

Paradoxically, the most reliable turbocharged variant is only the 90 hp TDI with a maximum torque of 202 Nm (coded 1Z or AHU). This turbodiesel appeared in the early nineties and was used in Audi, Golf III, Passat B4, Seat until 1996-1997.

Among the Skoda Octavia, the best TDI is considered to be the CMA. Its small constant-geometry turbocharger demonstrates much greater survivability than the 90-hp ALH's variable-geometry supercharger. The latter was prone to blade freezing, just like the 110 hp version.

The only weak point of SDI/TDI, especially in the early years of production, is the crankshaft damper pulley.

The engine of the Volkswagen EA827 family, with a volume of 1.8 liters, was released in 1983, and differs from the younger 1.6 liter engine in its increased piston stroke. The bottom of the engine is a cast-iron cylinder block, the head was installed on 8, 16 and 20 valves, and the latter was produced with a variable valve timing system at the intake and in the turbo version. VW engines of this type, 1.8 liter, have hydraulic compensators installed and valve adjustment is not required. The timing belt drive, belt replacement interval is ~60,000 km, if the belt breaks on an 8 valve engine, in most cases, the valve does not bend, but on 16 and 20 valve engines it bends. Since 1994, on the basis of this power unit, a turbo engine was created - 1.8T, which became widespread in Audi, Skoda, Seat and Volkswagen. This engine is also related to 2-liter 8-valve engines.

Weak points of EA113 / EA827, malfunctions and their causes

1. Problem with speed. It stalls. Check the airbag under the single injection, the coolant temperature sensor, the idle air valve and the throttle valve. 2. High fuel consumption. Check the lambda probe and coolant temperature sensor. 3. Engine noise. Usually this problem is caused by the hydraulic chain tensioner and is solved by replacing the tensioner with the chain.

4. Oil leaks. Most likely your oil cooler gasket has blown out, replace it and the leak will stop.

In addition, the crankcase ventilation system constantly becomes clogged and requires cleaning, the viscous coupling of the fan and the pump often fail, and in general, given the age of these naturally aspirated engines, anything can fail at any time. To summarize, it is worth noting: In general, the engine is not bad and, with proper maintenance, quite durable, but its time has passed and today it is worth looking towards more modern power units.

Volkswagen EA113 / EA827 engine tuning

Atmospheric. Turbo

For weak modifications of 1.8 liter Volkswagen engines, the simplest method of increasing power is to install a camshaft from more powerful engines, like ADZ, ABS and others. In addition, it is worth adding pistons from the same motor and ECU firmware; these manipulations will lead to a small but very noticeable increase in horsepower. Further increase in power, using factory parts, can be continued by installing a 16-valve cylinder head. If this is not enough, then you should buy a sports camshaft with a phase of 270 or more (Autotech for example), install a 4-2-1 spider, direct-flow exhaust, cold intake and tune it (for example in January). There is no point in trying to build something even more powerful; the engine is old and constant breakdowns will ruin the picture. There is no point in turbocharging the engine with a turbo kit or converting it into a standard VW 1.8T; almost everything along with the attachment will be replaced; only the cylinder block with the crankshaft will remain original. It’s much easier and more reliable to buy a contract 1.8 turbo engine and use the reliable factory 150-240 hp.

An article about the highest quality Volkswagen engines: their interesting features and technical characteristics. At the end of the article there is a video about VW hybrid engines.

The content of the article:

All Volkswagen engines have always been famous for their reliability and long service life, but even among them there are examples that stand out from the rest. Below we will look at the TOP 5 Volkswagen engines, characterized by high quality, performance and durability.

This power unit was produced from 2003 to 2010 and was installed on the Volkswagen Golf and Volkswagen Jetta, having proven itself to be an excellent power unit.

With a volume of 1.4 liters, the power produced is 140 hp. quite enough to fit it on cars with the maximum configuration, as well as station wagon models. The engine has a supercharger and compressor, which increases its operating efficiency, and is very unpretentiously “powered” by AI-95 gasoline.

Its design consists of a DOHC gas distribution system, four cylinders, each of which has four valves. This scheme makes it possible to use fuel and also remove exhaust gases in the best possible way.

This is one of the first engines of the concern that followed the downsizing program. It replaced the 1.8-liter engines familiar to the Golf and Jet, and its modification BMY seemed quite interesting to experts and owners. First of all, by combining a small volume with sufficient power. In addition, the engine turned out to be extremely economical in terms of fuel consumption, which won even more car enthusiasts over to its side.

Engineers managed to minimize the likelihood of problems with the gas distribution mechanism. A chain drive is used as a drive, which is not maintained during the entire period of operation, requiring complete replacement only during a major overhaul after 250-300 thousand km.

There is an automatic tension adjustment mechanism, which reduces the time spent on servicing the machine, since there is no need to check and adjust the chain tension during operation.

Another important point is the use of a special alloy for cylinder liners, which makes it possible to reduce the level of wear of this element.

A modern filtration system prevents metal chips and other contaminants from affecting the technical condition of engine components, which reduces the rate of wear of engine parts.

All these qualities allowed the BMY motor to take fifth place in our top.

This engine is installed on the following models:

Volkswagen Caddy;
Volkswagen Polo;
Volkswagen Golf;
Volkswagen Jetta.

It can also be found on some Skoda models, on which it is installed under contract.
This is a fairly new power unit, in operation since 2014. However, it has already shown good results in both endurance and reliability, and the manufacturer’s specialists say that this engine does not experience serious breakdowns.

The engine capacity is 1.6 liters, which allows you to get a power of 110 hp. To increase efficiency, multi-point fuel injection is used, which is a modern technology that minimizes losses of the fuel-air mixture. The engine uses only AI-95 gasoline as fuel; other options are not provided.

The four cylinders have 16 valves, which is the standard layout for most modern powertrains.

The design uses a belt as a timing drive, but the use of modern technologies makes it possible to achieve a mileage between replacements of 120 thousand km.

Among the disadvantages, one can note the high consumption of engine oil - even the official manual indicates an indicator of 500 grams per 1000 km. However, a lot depends on the lubricant used, since using cheap and low-quality oil can cause just such a problem.

In general, the engine life reaches 300 thousand km, which is more than good for modern cars. Until a major overhaul, no special problems arise, except for scheduled maintenance.

Years of existence of this engine have shown that it is a good unit, suitable for use in the city and on the highways. Sufficient endurance allows it to be used under heavy loads, for example, for moving the whole family. Such use does not affect the service life.

This is one of the most powerful and voluminous Volkswagen engines, which was installed on the Volkswagen Touareg in 2006-2010 and was distinguished by high power and efficiency. It was thanks to this power unit that Tuareg owners operated their car in the most difficult conditions.

The volume of this engine is 4.9 liters, which gives a maximum power of 351 hp, which is quite enough for reliable and confident movement on the most serious off-road conditions.

The presence of a high-quality load distribution system allows you to effectively transfer torque not only to the gearbox, but also to auxiliary units, including the winch.

The engine uses diesel fuel, consuming 11-12 liters per hundred kilometers. The fuel system uses original common-rail direct injection, which significantly increases the power of the unit with equal fuel consumption.

The engine is V-shaped, has 10 cylinders. Despite the impressive size of the engine, the design allows for optimal torque distribution, with 2 valves per cylinder.

The engine is very reliable and does not give the owner any trouble for 300-350 thousand km without major repairs, not counting scheduled maintenance. With proper use, according to the owners, it can last much longer.

A minor drawback is that it is demanding on fuel quality. When using contaminated diesel fuel, regular filter changes may be required, and problems with the injection pump may also arise. Although in practice such cases are rare.

According to drivers who regularly use a car with this engine, this is an excellent option, ideal for off-road use.

Every driver knows that old Volkswagen engines were distinguished by their longevity, which is why they were nicknamed “millionaires”. We are talking about engines that can operate for more than a million kilometers without major repairs.

The HZ power unit also falls into this category, although in fact its service life is 500-600 thousand km, sometimes more. But even this is twice as much as most modern cars, and if you take some budget models, then 5-6 times. Therefore, this particular motor is considered one of the best and most reliable.

This power unit was installed on the second generation Volkswagen Polo. Officially used from 1981 to 1994, after which it gave way to more modern models. But due to its popularity, it was produced at some factories under contract even in the “zero” years. Therefore, even now you can find relatively new contract HZ engines.

The engine capacity is only one liter, which is very small even by the standards of that time, and the power is only 45 hp. But, since it was used on small city cars, this was quite enough for normal use. An important factor was the endurance of this engine, which worked well at low speeds, as well as when long-term load was required.

The unit was completely unpretentious to fuel, running freely on AI-92 gasoline. Moreover, throughout the long history of this power unit, there are practically no known cases of its failure due to low-quality fuel.

The engine was powered by a carburetor, which consumed 8-9 liters of fuel per 100 km in mixed mode.

The design had 4 cylinders, each with two valves, but despite the rather old gas distribution scheme, this engine was both economical and efficient.

At the moment, you can find working engines that have been in operation for more than 30 years. This is probably the most important sign of quality, making this motor truly legendary.

One of the iconic models is the Volkswagen Transporter, which has become famous as a simple and reliable commercial vehicle. Despite the fact that it has been produced for a long time and has survived several generations, it is still popular. Thanks in no small part to its luxurious engines.

Over the entire period of its existence, the model has “tried” many different engines. But the best of the entire line of power units was recognized as CAAA, which can now be found on the following cars:

Volkswagen Caravelle;
Volkswagen Multivan;
Volkswagen Transporter.

This universal engine was produced from 2009 to 2015 and became so widespread that it is still manufactured under contract at a number of factories.

The main difference from the rest of the Volkswagen line of engines for commercial vehicles is the use of diesel fuel. Thus, it was possible to significantly reduce fuel consumption, which is very important for commercial transportation.

A volume of 2 liters makes it possible to obtain a power of 84 hp, which, with correctly selected torque, is quite enough for the stable functioning of the car. The transporter is a workhorse, and the resulting engine lives up to that title better than anyone.

The design has a turbine, which makes it possible not to lose speed on long climbs with a heavy load. Direct fuel injection makes the engine economical, consuming only 7.5-8 liters/100 km.

This engine is very reliable. Despite active use, no problems with increased wear or premature failure are observed.

Nowadays, Volkswagen has a variety of different configurations in its range of engines – from compact in-line threes to 6-liter V12s. Over all the many years of sales practice, the 4-cylinder options, naturally aspirated or with FSI direct injection, have proven to be the most popular.

Gradually, the company began to introduce turbocharged units, as well as those with a turbo with a compressor - TSI/TFSI, which provide impressive power with a small displacement. The most impressive is the 8-liter W16 engine installed in the Bugatti Veyron.

The only drawback of these powerful, reliable, popular motors is their complex design, which entails equally complex and expensive repairs, which can only be carried out by specialized services.

Video about VW hybrid engines:

In the CIS, the Volkswagen Polo Sedan is a well-known and quite popular model. The modern design and thoughtful solutions of the German concern Volkswagen allowed the budget sedan model to quickly get onto the list of real bestsellers. As you know, this car is assembled in Kaluga and for quite a long time it was produced with two reliable engines with a power of 85 and 105 hp.

However, after restyling, fans of the model were in for a real surprise, since in addition to new bumpers, a radiator grille, a trunk lid, improved sound insulation, a Golf steering wheel, LED headlights and a number of other improvements, the changes also affected the engine. Let's look at this in more detail.

Russian Polo Sedan engine

So, the new Volkswagen Polo Sedan, as before, is a model assembled in Kaluga, which has received improvements, including the engine. We are talking about the CFN motor of the E211 series. Let us immediately note that the new power unit has become even more powerful and more economical. It is also noteworthy that the affordable sedan will receive units produced at the plant in Kaluga.

As before, the engine with a displacement of 1.6 liters has two stages. Only now it is no longer 85 and 105 “horses”, but 90 and 110 hp. In the first case, it is 155 Nm, maximum speed is 178 km/h, acceleration to hundreds is 11.2 seconds. Fuel consumption in mixed mode is 5.7 liters. The more powerful 110-horsepower version also has similar torque, while the top speed is already 191 km/h. Acceleration to hundreds on the version with a manual transmission is 10.4 seconds.

As for the automatic Polo sedan, with the new engine the car accelerates more slowly than the previous modification. Acceleration takes 11.7 seconds. The consumption is also slightly higher, amounting to 5.9 liters, but this is quite expected for an automatic transmission.

We also note that the Germans also offer a sports version of the Polo. We are talking about the Polo GT, which will receive a 1.4-liter engine with 125 hp. Also, this car will be equipped with a 6-speed robotic gearbox.

Let's return to the engine. The new Polo engine, or rather its 90 and 110 hp MPI versions, have become more modern and environmentally friendly. The main feature of the modernized versions of CFN is aluminum. Improvements have made it possible to speed up the warm-up of the engine, and the stove also starts working faster and more efficiently.

The sedan also received an expanded package, which provides improved preparation for winter conditions, which allows for confident and stable driving down to -30 and below.

Other parts and components did not receive any major changes. Actually plastic, it can easily withstand high temperatures. The ignition system is non-contact, the oil pump has a pressure sensor, and the ability to configure it is implemented.

As for the resource, dealers voice a figure of 500,000 km. However, it should be understood that running-in, the quality of fuel, engine oil and maintenance, as well as operating features are factors that can greatly affect the service life, both for the better and for the worse.

You also need to pay attention to the issue and other parameters if the owner, for one reason or another, does not want to use the product offered by the official dealer as part of vehicle servicing.

Naturally, as in any other case, the service life of any engine will greatly depend on the first kilometers. We are talking about compliance with all recommendations and regulations. In this case, the Polo sedan is no exception. And you shouldn't rely on the stated 2 or 3 year warranty.

Let's go further, for the accurate and correct selection of “consumables” the engine number and its markings will greatly help. On a sedan from Kaluga, the serial number is located on the cylinder block under the body. Since the internal combustion engine is new, such information greatly facilitates the selection of engine oil, original spare parts or replacements from catalogs.

By the way, when choosing oils for this model, it is important to pay attention to the viscosity, which should be 5W30 or 5W40, as well as the tolerances. The oil must have approval VW 501 01, VW 502 00, VW 503 00, VW 504 00. ACEA A2 or A3 standard.

As for the manufacturer itself, some sources contain information that Castrol oil is poured into the Polo sedan engine during production. To change the oil, you need to buy about 4 liters; the manufacturer himself recommends pouring 3.6 liters into the engine, and the rest can be stored for topping up. This also needs to be monitored, as it can cause certain problems.

There is also information that power units undergo a so-called “cold run-in” of the engine right at the factory. Managers at car dealerships emphasize that it is for this reason that engines do not need additional running-in. However, in practice, experts pay attention to the fact that the engine, even the most modern one, still needs to be broken in.

The rules are quite simple: you must avoid driving without warming up, sudden starts, active braking, driving at a constant speed and at the same speed, driving in high gears, too high and too low speeds, driving uphill in high gear, engine braking, towing a trailer. etc.

In other words, during break-in there is no need to “load” the engine for at least the first thousand km. Also, after the first thousand, the oil and oil filter need to be changed, and always use high-quality gasoline not lower than AI-95. Then the next oil change is expected at 3 thousand km, and the 10 thousand km mark can be considered the complete completion of the break-in. After this, the oil is changed again, and the engine can continue to be gradually loaded.

What's the result?

As you can see, if we talk about the Volkswagen Polo Sedan model, the engine after restyling has become more powerful and lighter. Thanks to the modernized cylinder head, which is cast from aluminum, as well as a number of other improvements, this engine is a real technological breakthrough for the plant in Kaluga and can quite rightly be considered an internal combustion engine made in the Russian Federation.

In practice, the pre-restyling version has proven itself to be a worthy competitor to other brands and models on the market, which also promises success and increased demand for the updated version of the Polo.

Finally, we note that like any other car, the Polo sedan has its pros and cons. As for previous versions of the CFN engine, frequent knocking of the pistons when cold was noted. Drivers also experienced that the throttle sensor wires chafed, cracked, problems appeared with crankcase ventilation, and the valve of this system “stuck.”

Another common complaint is problems with the power supply system. At the same time, malfunctions in the operation of the injector and the appearance, as well as knocking of hydraulic compensators, cannot always be considered a drawback of the engine, since the main reason is the quality of the fuel and oil, as well as unscrupulous maintenance.

It is also important to understand that other competing models, to a greater or lesser extent, have certain and often similar problems. However, Volkswagen in many cases takes into account certain shortcomings when modifying its engines. This means that the new CFN E211 engine in the Polo Sedan may well turn out to be a successful and reliable engine, which is devoid of many of the shortcomings and “illnesses” of its predecessor. However, the strengths and weaknesses of this internal combustion engine will only be revealed by practical operation.

Jetta engine VW Jetta 1.6 liters

One of the four options is a non-turbocharged German engine with a working chamber volume of 1.6 liters, presented in the Volkswagen Jetta trim levels in two modifications.

The first of them has a power of 85 hp. and a recorded figure of 145 Nm of torque at 3.8 thousand revolutions of the Volkswagen Jetta engine.

When the speed reaches 5.2 thousand per minute, the power unit reaches the upper limit of its power. You can accelerate a Volkswagen Jetta to the notorious 100 km/h in 13 seconds.

When choosing this Volkswagen Jetta power unit, the owner will receive it in combination with a manual transmission, i.e. with mechanics.

The second modification (exactly the same volume) boasts 105 hp, and even additional distributed injection.

At 5.25 thousand revolutions, the maximum power indicator of the Volkswagen Jetta power plant is reached.

Although this engine option also does not have an additionally installed turbocharger. When equipped with a manual transmission engine, the Volkswagen Jetta can be accelerated to 100 km/h in 11.5 seconds; when equipped with an automatic transmission, this speed is achieved in 12.5 seconds, and the maximum is fixed at 180 km/h.

Engine VW Jetta Jetta 1.4 liters

Typically, Jetta engines, including the Jetta 1.4 engine, are gasoline. Just like the motors described above, The engine, with a displacement of 1.4 liters, is available in two options:

1. Turbocharged, 122-horsepower engine with cam injection, using TSI technology.

At 5.0 thousand revolutions, the engine power parameters reach their maximum value. At 1.5-4.0 thousand revolutions, a torque of 200 Nm is achieved.

The engine can be equipped with a mechanical or robotic gearbox. This Volkswagen Jetta configuration will reach 100 km/h significantly faster than the previous two, requiring only 9.8 seconds. The travel speed provided by this configuration is 202 km/h.

2. The engine, which also has a volume of 1.4 liters, has the greatest power, 150 hp. but it is equipped with a direct injection system into the combustion chamber, and also has an additional turbine installed.

This power unit operates using TSI technology, in which the engine has intermediate air cooling. This configuration option has the best dynamics of all the options presented above.

Power 150 hp will be achieved at 5.8 thousand revolutions, and the torque indicator of 240 Nm is achieved at 1.5-4.0 thousand revolutions. It comes with a Volkswagen Jetta engine and a robotic gearbox. Despite the rather modest engine size, the Jetta starts from 0 to 100 km/h in 8.6 seconds, and its maximum speed is 215 km/h.

Why is there such a difference in power between the two Jetta 1.4 engine options?

The fact is that the 122-horsepower engine has only one turbocharger, and the 150-horsepower engine has Twincharger double supercharging. This provides different motor power, but otherwise they are almost the same.

In any case, regardless of the engine size chosen for the Volkswagen Jetta model, it turns out to be a fairly economical unit, the power of which will delight even the most sophisticated car enthusiast.

Additional equipment in the form of crankcase protection is also considered one of the important points, since this is the basis for the safety of car equipment. Below we will look at how you can install protection on your Volkswagen car yourself.

VW Jetta engine number

Each power unit with which the car is equipped has its own identification number. It consists of an original letter combination and a digital part, which is the engine serial number. This engine number is located on the left at the junction of the engine compartment and the Volkswagen Jetta gearbox. Once again, this identification number and letter designation is duplicated on the cylinder head.

On Volkswagen cars you can often find a VIN - a number on the timing belt housing. In this case, the number is applied in the form of a sticker. It also contains a letter designation and VIN number. The letter part that the number contains is additionally on the information plate.

As a rule, this number consists of 9 characters - this is an original combination of letters and numbers. The first part is the letter designation of the power unit, and the second part, consisting of six characters, is the serial number. After the number of engines produced exceeds 999,999 units with the same designation in the letter component, each number now has another letter instead of the first digit. As a result, it turns out that each power unit has its own unique number, by which you can determine where and when it was produced.

Jetta engine protection and installation

In order for the Volkswagen Jetta to serve a long and faithful service, it is necessary to take care of the integrity and safety of its main operating components and assemblies. Most car owners consider installed engine protection to be a necessary condition for the safe operation of a vehicle. It will allow you to avoid mechanical damage or ordinary impacts, which are not uncommon on the roads.

Today, the road surface that exists in average cities is far from perfect, so the engine protection installed on the Volkswagen Jetta will reliably protect the most important parts of power equipment from serious damage and, as a result, expensive repairs.

It is no secret that most manufacturers, in order to save money, do not worry about installing protection on the engine. Therefore, car owners have to deal with this issue on their own.

To independently install crankcase protection on a Volkswagen Jetta, you will need a minimum of tools and time, but the result will provide maximum safety to the technical components of the car. So, to replace or install protection on a Volkswagen car, you will need a key with heads, the protection itself, purchased from official dealers or at any auto store.

The main thing to pay attention to is that the protection for the Volkswagen Jetta model must be made of steel, titanium or aluminum. From this list, the steel version is considered the most safe and reliable. In this case, the car owner receives a 2 mm plate made of high-grade metal with a total weight of 8-12 kg. For a Volkswagen Jetta that is not particularly tall, such protection is an ideal option, since it is quite rigid, but at the same time easily lends itself to any modifications or straightening.

According to the existing work regulations, engine protection requires scheduled replacement every 3-4 years. To do this job yourself, you need to perform a few simple steps:

if there is factory protection, it must be removed by unscrewing the bolts;
the new protection is attached in place of the standard one;
The same bolts are screwed in around the perimeter.

Thus, the entire self-installation process took approximately 15-20 minutes. Now the Volkswagen Jetta is not afraid of impacts with the bottom, since there is reliable crankcase protection.
