Engines 1.6 MPI, EA113 family
Description, modifications, characteristics, problems, resource
Motor bfq began to be produced in 2002, and it was the development of the engine AVU. It used an aluminum cylinder block with cast-iron liners, a cylinder diameter of 81 mm, a crankshaft with a piston stroke of 77.4 mm and a piston height of 29.7 mm was installed inside the block.
On top of the block is an aluminum 8-valve head with a single camshaft. The size of the inlet valves is 39.5 mm, the exhaust valves are 32.9 mm, the diameter of the valve stem is 6 mm. The camshaft rotates with the help of a timing belt, and the service life of this belt is 90 thousand km. (although according to factory recommendations, the belt is checked for the first time at 60,000 km, and then every 30,000 km until it is replaced at 120,000 km). The intake has a variable geometry manifold. This is the usual VW 1.6 MPI with multiport fuel injection and with Simos 3.3 control unit. It complies with the Euro 4 environmental class.
Fuel is supplied through injectors to a variable geometry plastic intake manifold. The amount of air required for the mixture is calculated based on the readings of the absolute pressure sensor (MAP sensor). Valve clearance adjustment is not required, as hydraulic compensators solve this problem. The neutralization of exhaust gases is carried out using a catalyst, before and after which there are lambda probes. An additional air supply pump is integrated into the exhaust system to help warm up the catalytic converter faster.
Engine versions 1.6 MPI (EA113) - BGU, BFQ, BSE, BSF, CCSA, CHGA
- In 2004, they began to produce the next version of this engine - BSE, which was distinguished by the absence of an EGR valve and a Simos 7.1 control unit;
- Together with BSE, they produced an engine BSF, which was distinguished by less stringent environmental standards (Euro-2);
- In 2007, Volkswagen launched the engine FlexFuel, which received the index CCSA, which is designed to run on E85 fuel (E85 is a mixture of 85% ethanol and 15% gasoline. One of the advantages of the E85 mixture is the reduction in exhaust emissions. But not everything is so sweet, since ethanol has a lower energy efficiency, then consumption compared to gasoline increases by 30%);
- Engine FlexFuel CCSA was taken as the basis for the creation, which runs on both gasoline and liquefied gas, but the use of ethanol is no longer allowed. The motor received an index CHGA, modified engine control unit software adapted to work on liquefied gas, the letter designation of the JHT gearbox, as on the BSE engine, and the timing, pistons and piston rings are taken from the engine FlexFuel CCSA. The engine uses a Simos 7PP control unit.
- In 2008, they began to transfer all these engines to the Euro-5 environmental class.
The engine was installed on:
- Audi A3 (8P) (2003 - 2012)
- Volkswagen Jetta 5 (1K) restyling (2005 - 2010)
- Volkswagen Golf 5 (2003 - 2008)

The main problems and disadvantages of engines 1 .6 MPI family EA113:
1) High engine oil consumption(manifested at high mileage)
Up to 150,000 km, the motor usually does not consume engine oil. Then preconditions can begin. In the worst case, you will have to disassemble the motor and check the condition as a whole, most likely due to a very high mileage (more than 250 t.km), the rings are stuck on the motor and an overhaul is needed. It will not be possible to get by with decarbonization, you need to do it well once and for a long time.
The problem may primarily be related to the quality of the oil itself (there are a lot of reviews that the oil burner is typical when using Castrol 5w-30 oil, which the dealer offers). Then, as a result, coked oil scraper rings can be obtained, and even when changing the oil to another, the oil burner can be preserved. Although it is better to use 5w-40 oil after 100 thousand kilometers.
Therefore, it is worth buying exceptionally good oil and changing it at least once every 10,000 km (and preferably once every 7,500 km), monitor its level and let the engine run throughout the entire range of speeds and loads.
2) Shaking, vibration at idle
4) Uneven spark erosion of the original three-pin plugs
On the motor 1.6 MPI EA113 interesting candles are installed from the factory - with three side electrodes. Everyone knows that the gap on the candle increases with time. This is the so-called spark erosion. When part of the metal on the electrode gradually disappears during the spark. Three side electrodes are made to increase the life of the candle. As one wears, the gap increases and the spark travels along a shorter path to the adjacent electrode. The wear of such candles turns out to be funny - the central electrode becomes triangular. It cannot be said that this is a sore of these motors. Normal spark plug wear. Simply, if a similar phenomenon is observed on a twisted candle, it is better to replace it. Because otherwise, during further operation, misfires will begin, and in the worst case, a broken ignition module will be added to the misfires. Timely replacement of candles on any engine prolongs the life of ignition coils. And if you save on candles, then you can change them together with the coil - the spark gap increases with time, the breakdown voltage increases, and the coil operates under more loaded conditions. Does she need it? The life of the coil is not sweet anyway, and then the candle throws up problems, so it goes on vacation ahead of time. And since this engine does not have individual coils, but one ignition module for 4 cylinders, you have to change it entirely, which is more expensive.
5) Oxidation of high-voltage contacts of ignition wires
Also, sores can include a common feature for all ignition modules - the oxidation of high-voltage contacts on the ignition wires. Often the same problem occurs on the motor 1.2TFSI CBZB. Skoda officially declares that nothing needs to be done with such oxidation and this does not interfere with normal operation. It may be so, but it is better to remove these oxides. It is necessary to carefully clean the oxides with a brush, sprinkle with WD and there will be no problems. Then you can still treat the connections with grease for high-voltage connections. This can only be done when taking into account that the ignition module itself is working. And if you need confidence - change the wires and coil.
6) Problems with the electronic thermostat
Electrical malfunctions include problems with the electronic thermostat, which was put on the modification of this motor with the designation BFQ. There are two options - either the thermostat control element itself burns out, or the antifreeze breaks through all the seals to the outside, and it likes to do this just through the contacts of this very element. And until you remove the connector, it is not visible. And even then, it is necessary to sag well to look into the connector on the thermostat. Although smart people use a mirror for this. And if the antifreeze still went through the contacts, not only the thermostat itself needs to be replaced, but also the pins in the return connector. You can only replace the thermocouple, but then there remains the possibility of leakage along the flange. From experience I will say that it is better to replace it together with the body.
7) Difficult start after a short stop
There is another common problem with these motors - difficult starting after a short stop. Especially noticeable in hot weather. It will stand, cool down for three or four hours - and picks up as if nothing had happened. It is fairly easy to diagnose. It is necessary to connect a pressure gauge to the fuel line. If the pressure drops after stopping the internal combustion engine, one or more fuel injectors are almost certainly leaking.
We unscrew the candles and look for a leaking nozzle with an endoscope. This or these injectors must be replaced by removing the intake manifold, fuel rail and replacing the injector. Particularly economical can wash the nozzle, but this is useless.
8) Error P0171 - lean mixture
There may be 2 options:
8.1. Usually after maintenance. When checking the condition of the throttle valve, remove the inlet pipe. And when they put it in place, they forget about the small hose from below under the crankcase pipe. They forget or do not notice, but it is not visible from above. Through this hose begins to suck air into the throttle space. The motor runs relatively normally, but after a while it gives an error P0171 - lean mixture. This is assuming the engine has a Mass Air Flow Sensor. He's a MAF sensor. Moreover, in addition to the lean mixture, misfires are also recorded, and people in a panic begin to change candles, wires, and so on, but what a business! Hose in place - problem solved.
8.2. The plastic intake manifold consists of two parts, at the junction there are rubber o-rings. Over time, the rubber dries up and cracks appear - through them, excess unaccounted for air enters the engine - appears error P0171. Also, this happens after not very competent maintenance with the disassembly of the collector - rubber rings are not always installed correctly. The problem is solved by replacing the intake manifold o-rings.
9) Compression drop in one of the cylinders
The most unpleasant cant on the mechanical side is a drop in compression in one of the cylinders. As a rule, the third or fourth cylinders are unlucky. In fact, on disassembled engines, stuck oil scraper rings are found in problematic cylinders. Most likely this is due to bad oil.
Compression should be measured if you notice increased oil consumption, which does not change even when using a more viscous 5w-40 oil, and also if the engine is frankly uneven (the usual slight twitches at idle do not count). To correct the situation with compression, it is necessary to overhaul the engine with the replacement of rings (the rest looks according to the state). But for the future, use only good motor oil with change intervals no longer than 10,000 km.
10) Torn off crankshaft position sensor
There is another interesting point that can be attributed more to features than to sores. The fact is that the crankshaft position sensor on this engine is located next to the oil filter. When at the next maintenance an inexperienced mechanic unscrews the filter with a three-legged puller, there is a chance to pull out the sensor connector. The three-arm puller is the key. If a cup or a chain - it is improbable. And with a paw, the wiring is clamped at the sensor connector and pulled out under the root. Repair will not work - only the replacement of the sensor. Moreover, the especially cunning ones manage to shift the blame on the client - we changed the oil for you, and why the check is on - we don’t know, this diagnostics is necessary. The motor is starting! It switches to emergency mode on the camshaft position sensor and somehow rides.

Engine resource
1.6 MPI EA113 (102 hp):
In general, BGU, BSE, BFQ, BSF and CCSA are low-power, but very simple and reliable motors, with normal maintenance and regular oil changes, they will travel 400-500 thousand km without any problems, and maybe even more. The experience of taxi drivers confirms this, since a lot of taxi fleets at one time used cars with these engines for their own purposes.
Engine tuning options
1.6 MPI EA113 (102 hp):
These motors were created for a leisurely ride around the city and no sport was implied when they were created. However, here you can upload another firmware (chip tuning) and get 110 or even up to 115 hp. But this is not even done for power, but to remove the excessive dullness of the motor.
It was equipped with several options for power plants, among which were both atmospheric and turbocharged engines. The modification with a 1.6-liter "aspirated" BSE with a capacity of 102 hp was very popular. This motor, which has received a lot of positive feedback, is considered one of the most reliable and trouble-free in the line of Volkswagen units.
The start of production of 1.6 MPI engines with the BSE index dates back to 2005. The engine was developed on the basis of a 1.6-liter petrol "four" BGU. In principle, both of these engines have a similar device, which is a development of an even older line of engines, which includes, for example, a unit with the ADP index. But, in general, all these power plants belong to the EA827 family, which has been leading its history since 1972.
Design features and characteristics of the 1.6 MPI BSE engine
The key to the reliability of BSE engines is a simple, time-tested design. The base is an aluminum cylinder block with cast iron liners. Cylinder diameter - 81 mm, piston stroke - 77.4 mm, compression ratio of the working mixture - 10.5: 1. Multi-point distributed injection, Simos 7 control system. Fuel is supplied through nozzles to a plastic intake manifold with variable geometry. The amount of air required for the mixture is calculated based on the readings of the absolute pressure sensor (MAP sensor). The gas distribution mechanism has eight valves, two for each cylinder. Valve clearance adjustment is not required, as hydraulic compensators solve this problem. The neutralization of exhaust gases is carried out using a catalyst, before and after which there are lambda probes. An additional air supply pump is integrated into the exhaust system to help warm up the catalytic converter faster.
The 1.6 BSE motor maintenance schedule includes a standard set of events for engines. The frequency of routine maintenance is the same as for other Skoda Octavia A5 power units. The engine oil is changed every 15,000 km (in severe operating conditions, preferably more often), the spark plugs are replaced every 60,000 km, the timing belt is replaced every 120,000 km (check every 30,000 km). It is necessary to monitor the condition of the timing belt in strict accordance with the regulations, since if it breaks, the valves bend, which threatens with expensive repairs.

Specifications Skoda Octavia A5 1.6 MPI
With all the advantages of the 102-horsepower 1.6 MPI, it is obvious that the owner of the Octavia can only count on a calm, measured ride with him. The traction characteristics of the engine are barely enough to give a more or less acceptable acceleration to a 1.3-ton car. If the model is equipped with a 5-speed manual, acceleration to 100 km / h takes 12.3 seconds, the modification with a 6-band "automatic" is even slower - 14.1 seconds. If in the urban crowd such dynamics are quite enough for successful maneuvering, then when driving on a suburban highway with one lane in each direction, the moment for overtaking must be chosen very carefully.
Chip tuning can add a little agility to the car, but it will not give a significant increase. At best, the increase in power and torque will be 5-10%, which is almost not noticeable. In addition, it is not known how manipulations with the control unit will affect the engine resource. But with factory settings and with timely maintenance, the motor is able to “walk” 250-300 thousand km.

Pros and cons
A simple internal combustion engine device provides a resource of more than 500,000 km of run. Even if the timing belt breaks, no unpleasant consequences for the user are expected, since the piston does not bend the valve when it meets them. Do-it-yourself maintenance and forcing in garage conditions is not difficult.
An exhaust manifold
An unpleasant feature of the power drive is increased vibration (almost convulsions) at the time of winding. Immediately after warming up, they disappear completely; it is impossible to get rid of this defect due to the presence of an additional compressor.
In principle, the 1.6 liter BSE engine has only two competitors - the more powerful 1.8 liter and the economical 1.2 liter. Only high-quality attachments were used.

Thus, the production volumes of the BSE motor for such a number of models from three manufacturers are very impressive. With low gasoline consumption, cars have moderate driving dynamics.
Service Schedule BSE 1.6L/102L. With.
- the timing belt and attachments after 50,000 km are subject to routine replacement;
- the manufacturer provides for crankcase ventilation cleaning every 2 years;
- after 7500 km, the manufacturer recommends replacing the oil and engine oil filters;
- it is recommended to use a new fuel filter after 40,000 runs;
- air filter according to the manufacturer, must be replaced once a year;
- antifreeze additives are not effective after 40,000 km;
- the resource of spark plugs is 20,000 mileage;
- burnouts in the intake manifold of engines appear after 60,000 km.
Flushing the crankcase ventilation
Motors leave the factory with working fluids of medium quality.
Overview of faults and how to fix them
With high mileage, the BSE motor may make a knock, the cause of which lies either in worn hydraulic lifters or the timing belt tensioner. The problem is solved by replacing the hydraulic lifters and the timing belt kit. Less commonly, other malfunctions occur:
Motor tuning options
Due to the design features, the BSE engine is specially “shrink” to meet Euro-4 standards. Moreover, the usual chip tuning, of course, will add 5 - 10 liters. s., but against the general background of 102 liters. With. the effect will be almost imperceptible. Most often, the following type of tuning is used for the BSE version:

Reliability, problems and repair of engines BSE BFQ BSF
The BFQ motor began to be produced in 2002, and it was a development of AVU. An aluminum cylinder block with cast-iron liners was used here, the cylinder diameter was 81 mm, a crankshaft with a piston stroke of 77.4 mm and a piston height of 29.7 mm was installed inside the block.
On top of the block is an aluminum 8-valve head with a single camshaft. The size of the inlet valves is 39.5 mm, the exhaust valves are 32.9 mm, the diameter of the valve stem is 6 mm. The camshaft rotates with the help of a timing belt, and the service life of this belt is 90 thousand km.
The intake has a variable geometry manifold.
This is a regular VW 1.6 MPI with multiport fuel injection and a Simos 3.3 control unit. It complies with the Euro 4 environmental class.
In 2004, they began to produce the next version of this engine - BSE, which was distinguished by the absence of an EGR valve and a Simos 7.1 control unit.
Together with BSE, they produced the BSF engine, which was distinguished by less stringent environmental standards (Euro-2).
In 2007, Volkswagen launched the CCSA engine, which is designed to run on the E85.
In 2008, they began to transfer all these engines to the Euro-5 environmental class.
These VW 1.6 MPi engines share common roots with 1.8 liter AGN, ANN, ADR and 2 liter ADY, AGG, AQY and other engines.
The release of these 8-valve engines continued until 2015, but since 2010 they have been replaced by 1.2 TSI.
Disadvantages and problems of engines EA113
1. Zhor oil. You need to disassemble the motor and check the condition as a whole, most likely you have a huge mileage, the rings are stuck and you need a major overhaul. It will not be possible to get by with decarbonization, you need to do it well once and for a long time.
2. Shaking, vibration at idle. Increasing idle speed may help. The second reason for this may be air leaks, you need to remove the intake manifold, replace the gaskets and put everything in your mind.
In general, BSE, BFQ, BSF and BGU are low-power, but very simple and reliable motors, with normal maintenance and regular oil changes, they will travel 400-500 thousand km and even more without problems.

Engine tuning BSE BFQ BSF
These motors were created for a leisurely ride around the city and no sport was implied when they were created. Nevertheless, aggressive firmware can be uploaded here and get 110 or even up to 115 hp. But this is not even done for power, but to remove the excessive dullness of the motor.
Power plants from leading German companies in the automotive industry have always been famous for their reliability and unpretentiousness. At the same time, engines from the Volkswagen concern can boast of high efficiency, solid power, which provides the car with no less attractive dynamic characteristics. All these qualities distinguished BSE, BSF, BCF motors from other competitive installations. Partly for this reason, BSE powered vehicles are common on domestic roads. The owners give preference to the "Germans" not only for the wide range of equipment, which includes many comprehensive equipment and options, but also for the high resource of components and assemblies of key systems.
You can literally meet cars with a BSE engine installed under the hood at every step: these are the Passat B6, Volkswagen Golf 6, Touran, Jetta, Skoda Octavia. All these cars, to one degree or another, have become widespread in the territory of the post-Soviet space. The Volkswagen concern, which first introduced the unit in 2005, is considered the parent of the BSE. Subsidiaries, mainly Skoda and Audi, equip their developments with the same installation. In the article we will tell you what the resource of the BSE engine is, highlight the main advantages and disadvantages of the installation, as well as all sorts of problems that the owner of a car with this engine may encounter.
The history of the emergence of BSE
In 2002, German engineers first introduced the BFQ engine, which was later upgraded several times. It was the basis of BFQ that served as the further development and production of technically advanced installations. The motor was designed on the basis of AVU, in fact, becoming a continuation and development of the already proven family of engines. If in AVU the cylinder block was completely cast iron, then the design and technological engineering solutions required a different approach at that time. Therefore, the motor was endowed with an aluminum cylinder block and cast-iron liners. On top of the block is an aluminum 8-valve head with a single camshaft.
The Germans started creating functional power plants for their subsequent installation on budget models of the VAG group in 2005. Thus, resistant to adverse operating conditions and reliable BSF and BSE motors appeared, which were equipped with models that are very popular in the countries of the former CIS. The BSE engine is also equipped with an 8-valve gas distribution mechanism. Its working volume is 1.6 liters, and peak power reaches 102 horsepower. In technical terms, it is quite simple, in some way “primitive”, but, most importantly for a domestic car owner, it is less picky about the quality of fuel being refueled, which means that it “digests” gasoline of any quality without much difficulty. The first eight-valve BSE was installed on the fifth generation VW Golf in 2005. The car, like the engine itself, exceeded all expectations. Today it is one of the most popular representatives of the golf car class not only in Russia, but throughout Europe.
Design features and characteristics
The BSE cylinder block is also all aluminum with cast iron liners. The cylinder bore is 81 mm, the piston stroke is 77.4 mm, and the compression ratio is 10.5:1. A distinctive feature of the engine is the modernized and redesigned exhaust gas recirculation system in its own way. If in the previous appearance of BSE power plants, gases contributed to the enrichment of the working mixture, returning to the engine cylinders, then in the new engine the principle of operation is built somewhat differently. At BSE, the recirculation system was thoroughly redone, but at BSF they decided to abandon it altogether. Such a decision had a positive effect on reliability, efficiency, as well as the cost of manufacturing motors.
But the reconfiguration of the principle of operation of the motor had a negative impact on the environmental performance of the engine. BSE environmental standards have fallen to Euro-4 standards, while the smoothness and softness of the power plant have also been violated. The owners of the VAG auto group note that, when starting to “cold”, the engine makes strange, frightening sounds, especially for novice drivers, resembling a rattle and clatter. The appearance of specific noise during engine operation can be attributed to the specificity of the installation. But with an increase in the temperature of the system to operating indicators, all extraneous sounds disappear.
Service Regulations and Resource BSE 1.6
According to official information from Volkswagen, a total of about 500,000 BSEs have been produced since 2005 to date. Unlike BSF, this motor still has a partial ventilation system. Due to the additionally installed fan, forcing air is supplied, the feature of which is a slight shaking of the motor at low speeds. If you notice a slight vibration in a Skoda Octavia 1.6 or VW Golf 5, there is no need to panic - this is a normal phenomenon for these cars. It is due to the fact that during operation at idle and low speeds, a lean mixture enters the cylinders of the power plant. With a full-fledged gas recirculation system, the mixture was further enriched.
According to the manuals of German automotive companies for servicing the BSE engine, the driver should:
- After every 10 thousand kilometers, completely replace the lubricant in the power plant system. For these purposes, the engine oil recommended by the manufacturer with a viscosity index of 0W-40, 5W-40, 5W-30 is best suited. For a complete and effective replacement, a container of lubricant in the amount of 4.5 liters is enough;
- After 45-60 thousand kilometers, antifreeze and gear oil change;
- Regularly inspect the condition of consumables, as well as carry out their complex replacement in time: air and oil filters, cylinder head gasket should be changed according to the deadlines specified by the manufacturers;
- Periodically carry out comprehensive diagnostics of the most important vehicle systems in order to timely detect even minor malfunctions. After passing 40-50 thousand km, be sure to inspect the spark plugs, they must work properly, supply a high-quality spark, and there should be no plaque and traces of burning on their surface.
By following simple tips and tricks, owners of cars with a BSE engine installed under the hood manage to cover impressive distances. Instances of Skoda, Volkswagen models with such an engine under the hood, and having passed over 500,000 thousand, are not rare, and are quite common. The manufacturer managed to endow the installation with reliability and a long service life due to the use of simple but effective technologies during the design of the engine. VW is in no hurry to reveal all the secrets, lifting the curtain, so the company does not talk about the actual resource indicator. But the BSE warranty resource is 200 thousand km, if you look at the practice of operating Volkswagen cars, we can safely say that the minimum BSE resource is 400,000 kilometers.
Possible engine malfunctions
This power unit can be safely listed as a real hard worker, but it is also characterized by some "chronic" diseases and typical malfunctions. The main problem is related to fuel injection at idle. The BSE engine is equipped with a fuel injection system, the system itself is durable, but the gas distribution mechanism often fails.
As a timing drive, a belt is installed, which has a resource of 80-100 thousand km. Cases when it is torn are rare and are of a single nature. With a broken valve belt, the valves bend, so it is better to replace the timing belt after 90 thousand, even if it does not show symptoms of a malfunction. The engine does not knock and is not prone to overheating, which adversely affect the resource of the aluminum cylinder block. In all other respects - a fairly reliable motor, excellent pulling on the "bottoms".
Feedback from drivers about the reliability of the motor
A lot has been said about the warming up of VAG engines, the topic of conversation has not bypassed the BSE either. According to the reviews of car owners, the engine at idle heats up well, but rather slowly. It's all about specifically built air cooling. However, in 4-5 minutes the unit fully reaches the operating temperature, which means that you can start driving a car. But it is also worth remembering that the first few kilometers should not be overloaded with the installation. VAG car owners will talk in detail about the BSE engine life and all the features of the car's "heart".
- Yuri, Tula. I have a 2006 Volkswagen Golf. Mileage today is already 240 thousand kilometers. The engine is high-quality, high-torque, I like the dynamism of the Golf, the car accelerates up to a hundred very quickly. And in general, with pressing the accelerator pedal, the speed instantly takes off and the car rushes at full speed. The only thing that I don’t like and is slightly alarming is that after starting the first minutes the engine knocks. It used to be a distant clatter, now it's a direct obsessive, sharp sound. So I'm thinking it's not the cams or the valves? In general, extraneous noise in the operation of this engine is the norm. But it is necessary to distinguish between noises and navigate according to the situation. Even in the manual for the car it is written that the engine knocks on the “cold” one. I fill the oil with EDGE 5W-30, 4.5 liters, I change it every 8 thousand. Might have to go in for diagnostics.
- Sergei, Perm. Now on the speedometer of my Skoda Octavia 225 thousand kilometers. I fill in only EDGE 0W-30, I change it about once every 12 thousand, it happens in different ways. The engine does not cause any problems, during this time it has only replaced the timing belt twice. Oil from replacement to replacement, however, has to be topped up 300 grams somewhere for every thousand runs. I didn’t change the pump, at the service the car is serviced by one person, he says, if it is working, then you can not change it yet, nothing will happen. I trust him, because, in principle, the engine works stably and without interruption. Sometimes I notice how the knocking becomes more frequent during the start of the engine, similar to when faulty hydraulic lifters knock. I went several times for diagnostics, everywhere they say that the engine and compensators are working. Therefore, I had to put up with it, I just do not pay attention to extraneous noises. A car with a BSE engine is able to “plow” 450-500 thousand kilometers calmly.
- Anatoly, Moscow. Hi all! I have a 2007 Volkswagen Caddy, BSE 1.6 engine, mileage of 220,000 kilometers. Everyone likes the car: from the spaciousness and comfort of the cabin, to acceleration and handling. For all the time I changed the cylinder head gasket twice, the radiator, after I noticed traces of antifreeze. I also changed the timing belt twice, its resource is about 100,000 km, but it is better to change it earlier, because if it breaks, it will bend the valves. I’ll write another service, it may come in handy for someone: it’s not necessary to change the air and fuel filter after 15-20 thousand km using the original repair kit, you can find high-quality analogues. Further check of the candles every 10,000 km is mandatory, it is better not to “walk” on one longer than 50,000 km. With the replacement of the belt, I recommend immediately installing new rollers and a pump - every 100 thousand mileage. Antifreeze and brake fluid in good condition, at least once a year.
- Mikhail, Saratov. I have a 2009 Volkswagen Jetta with 120,000 miles. More recently, the BSE “sore” made itself felt, I don’t even know what could be the cause, because before the engine started without extraneous noise. I talked with the masters, went to the diagnostics, which showed that the engine was like new! In the course of a conversation with owners of similar cars with the same 1.6-liter engine, I found out: nozzles can dig in, single cases, but with the replacement of nozzles, the clatter at the start disappeared. The knock is provoked by a faulty absorber valve, which should also not be ruled out. I didn’t change the oil, I always used the recommended one, they also told me at the service station that it could knock because of gasoline.
- Stanislav, Yekaterinburg. On my Skoda Octavia 1.6 I have never noticed anything like this. Today, the mileage is 220 thousand km, the engine runs confidently, I change engine oil every 8-10 thousand km. The only thing I once noticed is how the car is supported at idle about 500 rpm, probably this is due to a lean working mixture. One experienced auto mechanic advised me to adjust the idle speed by setting the VAG Com minimum rpm at around 800. It was like a shot. Now the engine runs clean and smooth. Perhaps my experience will come in handy for someone. It would be great.
- Ilya, Khabarovsk. From my own experience I can say that if all the oddities inherent in this engine appear “hot”, you should look for the cause of the malfunction. If it's "cold", then it's okay. On the "hot" when it knocks, most likely it's the injectors. It is not for nothing that the service stations sin on the quality of gasoline, this can really happen due to contamination of the nozzles with small particles. As a result, they begin to leak, as they do not completely close. In this case, there is nothing left but to change the nozzles themselves. I drive a Volkswagen Touran 1.6, the mileage today is 280 thousand kilometers. Diagnostics shows that the engine of my car is in excellent condition, and is able to pass the same amount. Therefore, I am sure that the real BSE resource is at least 550,000 kilometers.
The BSE engine has a small number of disadvantages. The manufacturer was forced to deprive him of the gas circulation system in order to reduce the cost of producing the motor. As a result, motorists have been able to acquire a European car with a reliable and resource-intensive power unit for a decade. Judging by the reviews of the owners of the VAG auto group, the BSE resource is at least 500 thousand kilometers.
