Major problems and weaknesses. Are TSI engines reliable? Main problems and weaknesses Passat 1.4 TSI 122 liters with problems

Of course, such recommendations should be not only for tSI motorsBut in general for all ICA. However, the TSI engine does not like short-term driving in cold conditions. This type of motor requires a good heating, and if you ride a short distance, and even in a strong frost, it leads to the rapid wear of the details of the cylinder-piston group. But, if you still have to ride for minor distances in harsh climatic conditions, then you need to often change the spark plugs.

Weak places of such engines

• FURS of modern cars require a careful relationship and timely passage of car maintenance.
• TSI engines are eating a lot of engine oil. Even new such engines consume 1 liter of oil per 1000 km of run. Therefore, it often happens that the spark plugs splashes with oil.
• In the design of the car with the engine TSI chain drive of the gas distribution mechanism (timing). Weak link in the chain drive of such engines is not a reliable chain tensioner. In addition, the chain is extended earlier than the development of its resource. The links of the stretched chain are jumping through the tooth and provide a set of valves with pistons. The exact mileage on the chain on the regulations does not give manufacturers. The chain may fail by 50 thousand km, and it can regularly work up to 150 thousand km.
• It happens that oil workers or valves are clogged. This is especially true of such cars whose drivers chase on maximum speed. With high engine speed, ventilation in the crankcase cannot be properly carried out. Cocking the oil worker is obtained due to the use of low-quality engine oil or simply not a suitable brand. Therefore, it is necessary to check periodic and, if instead of a clear oil on the dipstick already dirty oil, then forward to replace.

To increase the engine frequency period, it is recommended to listen to how the motor works that knocks. If the operation of the chain is heard, then you need to diagnose, perhaps the chain has already stretched. Also, while the car has a new and little "ran", it is recommended to pour specialists. We have already considered that better, eco or euros.
Specialists in repair and maintenance modern cars Recommend not to leave the car at speed without raised manual brakes. They explain this by the fact that if the car rolling back back being activated on any transmission of the box, then the chain links can occur on one tooth.

Turbines from TSI engines easily pass to 150 thousand km of run. From this point of view, the DVS TSI 1.4 122 and 150 hp Reliable. New such engines can be safely acquired, and used used well to examine well, to diagnose as it should, otherwise you can buy a cat in a bag.

Question from the reader:

« Dear Blog author, now sold his car and select a new one, very much, but she has two engines, one without a turbine (I don't really want, because weak) and the TSI engine (powerful, but with a turbine). There are many different opinions. Tell me, and reliable tSI engines And is it worth taking it? Thanks in advance, Gaidar»

Good day, the question is interesting, I already wrote. However, today is locally about this model ...

Reliability common atmospheric engine It will be higher than the turbocharged is an axiom. Therefore, if you want to ride a long time and not to look at "additional" problems, take normal option. However, you will drive like a "vegetable" (locally about Skoda Rapid), all because the power of the usual unit - 102 hp Little! If we consider that classmates, such as, for example, Hyundai Solaris. - Power of about 120 hp. (if you do not consider AVEO), and the difference in 20 hp Significant! That wants our people not to be "outcast" in the stream and looks at TSI.

About turbine

It should be noted that the engines that are supplied to this version of the car have a volume of 1.4 liters (power of 90 kW, which corresponds to about 122 hp, well, can a little more). However, this motor has variations in 140, and in 180 hp, it seems to be the same, but the power is much more. If you calculate the variations of such an engine, their already - 10! You can distinguish them by power, the simplest 122 hp, the average - 140, the most powerful 180 hp

So what I want to tell - not all turbines are the same, they differ very critical. If you extend:

1) on weak models (up to 122) is one turbocharger, model - TD02

2) On powerful models (more than 122) - Eaton TVs turbocharger Superior KKK K03, that is, double supervising, which avoids the turbo pit!

How it becomes clear - powerful models are harder, so they have more to break. But the "weak" models, "simpler", so reliability is slightly higher.

If you take a simple option (as in our case), then the reliability of its turbine on high level - when complying with all operational norms (oil replacement, fuel, etc.), this turbine runs 150-200,000 kilometers. And even poor-quality fuel immediately will not "kill" it, 70 - 90,000 leaving. If you live in a small town, then the mileage will have about 15 - 20,000 per year, it means even with the worst combination of events (poor fuel), ride 3 to 4 years, freely. I have a friend who has been driving with such an aggregate for 7 years and everything is fine. Wow, with a turbine dealt with, go on.

Building and inside

What to say the reliability of the block itself and internal parts is no doubt at a high level, with the exception of one node. Let's in order.

Consists (simplified scheme) :

1) cast iron cylinder block

2) and "rods"

3) Aluminum, 16 valve head block with two shafts and hydraulic system system with phase inspection on the inlet shaft.

4) direct injection system.

5) Systems distribution system - chain.

As you see the TSI itself, a standard reliable unit. But it has one "weak link", which spoils the whole picture, especially in powerful versions (from 140 and higher) is a timing chain.

Here it is "unemployed" and is designed for the entire service life. However, as practice has shown, it is pulled out after 50 - 70,000 on "powerful" versions, and after 100 - 120,000 on weaker. After it happened - noise in the engine appears, a strong crackle seems to be a diesel (it is impossible to confuse it with anything), it can also jump on one thing - two levels, then you will not start the engine at all.

Now Volkswagen engineers are "fighting" over solving the problem, the resource has slightly increased. Cars since 2014 even powerful versions Go to 150,000, but the fact remains a fact - the chain is now stretched. Again, you will be enough for a long time if you drive 15,000 per year, then almost 10 years old.

About oil and fuel

What to say reliability TSI directly depends on what you have in it! Do not save on oil, buy only engine desired synthetic oils. Also these aggregates, have a small "appetite", spend gradually oil - this is normal, per 10000 km, consumption can reach 0.5 - 1 liter (tribute for the turbine). Gasoline is required not less than 95, it is not necessary to buy on 92, then the consumption will decrease and the resource will increase a little. Place on proven gas stations (do not leave "Surogat") - although it concerns all cars.

About vibration and warming

Many owners are 1,4 TSI in the cold period of time, notice - "Trojections" or vibration. But after everything is warming up. Guys are not a breakdown, it is such a principle of work. It is worth noting that these aggregates are warming up longer than ordinary "atmospheric" it is also normal, all turbocharged units have "cold blood".

Finally

Despite all the few sores of this model, it is one of the most reliable turbocharged engines, as the manufacturer itself assures, with proper and calm operation, you can ride 150,000 km, without looking into it, then change the chain, we look at it (repair - change the turbine) and still At least 150,000.

The old EA111 model gathered a lot of awards and recognition, since 2014, the release of the EA211 model was launched, according to the manufacturer, the engine resource was much increased.

So if you thought to take new Rapid With TSI, then there is most likely "second generation", take not be afraid.

Finally, my favorite motor. This is a 1.4 liter engine, turbocharged and direct injection. Meet Caxa. Personally, for me, the most reliable from the penultimate Vagovsky motors. Yes, there are some shoals, but everything is treated and the motor feels normally. Power is enough - 122 horses quite grabs and Octavia, and Yeti, and for Rapid it is generally a top motor. Not to mention a good opportunity for chip tuning. Of the features of the motor, in addition to the turbine and fuel system high pressure:

• unworthy chain GRM
• phase inspector inlet tree
• liquid intercooler, which is installed in the intake manifold, as 1.2 CBZB
• accordingly, the two-circuit cooling system

• Turbocharger. The turbine itself is reliable and feels great and large runs for normal oil. Problems arise with excess gases bypasic valve. Wastegate is called. Whether the designers did not calculate the diameter of the hole under the axis of this valve in the turbine ... and maybe the wrong material was picked up. The essence is one - to one hundred thousand mileage, or even before the valve axis in the turbine case begins to eat. Bite. Walk badly. Engine block lights error P0234 on Advance Pressure Regulation, Motor goes into emergency mode And the car does not go. Diagnosed quite simple. It is good that the adduction regulator actuator is an old type here - vacuum. Therefore, I apply a small air pressure on this actuator. I use a vacuum pistol for this. With a pressure of 0.8 - 1 bar, the rod without jams should be moved to the stop.

But the replacement is good when she is guaranteed ...

In the post-warranty car, the owner, of course, does not particularly want to part with his blood. The turbine is never cheap. Therefore, alternative methods are used. It is worth a little divorced hinged equipment The engine - and the rod of the regulator is available for influences.

Impact usually with a wire crochet. But just so there is no meaning there is no meaning there. Therefore, for a start, I spray it and the axis in the turbine solvent Rust Rost Off (or WD will also come true).

When the rod agreed well, fix the result of high temperature copper lubricant - Do not take care, I process all moving parts. Checking - the rod smoothly walks in both directions. This repair helps for half a year. All cheaper than turbine replacement.

• On this motor, the fuel is poured directly into the cylinders. Therefore, we have in addition to the usual fuel pump in the tank, the additional high pressure fuel pump. It is installed on the head of the cylinder block and drives the camshaft cam. At one time I suffered from one octavia for several months. The owner complained about the poor morning launch and a mistake on a rich mixture. The problem arose more and more often. I was able to solve this rebus only when the oil in the engine was much more than necessary, and it strongly gave gasoline. Even this was hard to call it - it hurts liquid. It turned out, gasoline through a leaky fuel pump seal straightforwards in the crankcase and rigged the mixture. Two years have not passed, as Skoda still released an revocation that on motors 1.4 TFSI CAXA and 1.2 TFSI CBZB high-pressure fuel pumps sometimes give to flow. To check this in addition to checking the level and quality of oil, it is also proposed to unscrew the pump from the engine and holding the rod, turn on the ignition. With this earns the pump low pressure In the tank. The rod on a good pump rod will remain dry, if there is a flow - the pump is changing, the repair has not mastered until.

• An innovative charge air cooling system is an intercooler, is in the intake manifold. The cooling fluid passes through it, which is driven through an additional cooling radiator with an electrical pump. TOTAL three radiator on the car - One for the air conditioner, one for the engine and the third for the intercooler and the turbine.

To be honest, in the latter is not strong, there are specialists with argon welding. This is to them. Although "to remove - put" then another adventure!

The intercooler does not particularly intend and rests on the pipes into the engine shield.

I make a correction: In previous articles, when describing the CBZB motor with the same cooling system: there it is removed perfectly, and in the case of CAXA will have to sweat.

Well, what else ... talking about suddenly dying ignition coils I will not be a trifle and happens on other motors.

Engine 1.4 TSI / TFSI EA11 series debuted in the spring of 2006. The 140-strong option fell under the hood Volkswagen Golf V. Modern motor With direct injection and four valves on the cylinder quickly conquered the hearts of the jury of the "Engine" contest. Since force aggregate Every year collected leading awards in various nominations. But no prestigious titles guarantee reliability, as unexpectedly for themselves, with sprinkle and annoyance, tens of thousands of customers around the world have learned.

2010 brought long-awaited modernization. The timing tensioner was improved, and instead of the chain, the timing belt was installed. In 2013, a motor version equipped with a COD system (Cylinder-on-Demand) system was released, which during the movement without load disconnects two cylinders, which reduces fuel consumption.

Engine 1.4 TSI / TFSI has 8 modifications with a capacity from 122 to 185 hp. Weak versions (122 and 125 hp) were equipped with a turbocharger, and strong (from 140 hp) also a mechanical compressor. The last combination allowed to solve the problem of "turbump" (failure and lack of thrust on low revolutions). In everyday operation, the advantages of motors 1.4 TSI / TFSI rated not only drivers who prefer good dynamics. Engines demonstrated good fuel efficiency (about 7-8 l / 100 km). This motor is very widely used in model row concern Volkswagen.: Volkswagen Polo., Skoda Fabia., Tiguan, Octavia and Seat Alhambra.

Problems and malfunctions

As the infamous 2.0 TDI with pump-nozzles, and 1.4 TSI / TFSI did not differ in exemplary reliability. Unfortunately, "children's diseases" strongly spoiled a brand reputation and undermined customer confidence. The most numerous charges received a defective tensioner chain chain and a premature Tensive Timing Chain. Mostly suffered from 140 and 170 hp engines. The cost of repair is about 300 dollars. Also refused the system of changing the phases of gas distribution (300-500 dollars) - a characteristic "diesel" noise appeared.

Nevertheless, this is nothing compared to the destructive rings and pistons. The cost of such a repair is already colossal. Mechanics believe that problems with piston are associated with poor-quality fuels causing devastating detonation.

Among other defects are worth noting frequent problems With Pompey (about 300 dollars) and with an injection system (a set of about 300 dollars). In the first case, the electromagnetic pulley coupling is slipped during overclocking between 2500 and 3500 rpm. In the second case, there are problems with the launch, and error messages appear.

The least problematic turned out to be modifications without a compressor - with a capacity of 122-125 hp.

Should I buy cars with 1.4 TSI / TFSI?

Cars with 1.4 TSI / TFSI, collected until 2010, may turn out to be a risky choice. But not all of them must bring problems. It all depends on the previous owner and operating conditions. Engine inspection is desirable to entrust an experienced specialist. Chances of encountering serious malfunctions in younger cars (since 2010) are small. Therefore, it is necessary to focus on searching specimens with modernized engines. Although they are more expensive, but in the future they will overcome your money, time and nerves.

TSI series motors are turbocharged gasoline engines with a direct fuel injection system.

History and design

TSI is decrypted as Turbo Stratified Injection - "Turbo Layered Injection". Company Audi. The same engines denotes TFSI, F - FUEL (fuel).

Since 2012, the concern Vag goes to new ruler TSI motors.

The old ruler also remains popular on secondary market. Consider one of its representatives - Engine 1.4 TSI of the first generation, EA11 series.

This 4-cylinder (4 valves per cylinder) injector with a turbine was produced from November 2005 and was intended for compact and medium-sized concern models. It was supposed to replace 2.0- and 1.8-liter motors of the T. series

The design of the motor is as follows: this is a cast iron block of cylinders with wrought steel crankshaft, the intake manifold is made of plastic. GBC is made of aluminum alloy.

The timing chain is designed for the entire service life.

1.4 TSI debut took place on the "charged" VW Golf GT.

Due to consistent supervision (mechanical compressor + turbine), the motor developed 170 hp. After half a year, a 140-strong version appeared, a decoded to 122 hp was published later on the market. Modification without a mechanical compressor.

The release of 1.4 TSI continued until February 2012, when it was changed by the EA211 series. But EA111 continued to mount in the models that were presented before the appearance of the EA211.

Installed 1.4 TSI on

• Audi A1 - C 2010
• Audi A3 - 2010-2012
• SEAT Ibiza - C 2009
• SEAT LEON - Since 2007
• Skoda Superb - since 2008
• Skoda Yeti - from 2010
• VW Passat B6 - 2007-2010
• VW Golf - 2005-2012
• VW Jetta - 2006-2011
• VW Scirocco - since 2008
• VW Touran - 2006-2010
• VW Tiguan - since 2007.

Since its debut 1.4 TSI, it was honored for excellent dynamics and a relatively small fuel consumption.

Particularly impressed by the owners of the version with a consistent superior. The consumption of gasoline at the same time was 7.5 - 8 liters per 100 km of way.

Modifications:

• Caxa. - 122 hp, 200 nm

• Cave / CThe - 180 hp, 250 nm

Typical faults 1.4 TSI

destruction of pistons

This defect is the characteristic problem of the first 160- and 170-strong versions of 1.4 TSI. Due to the intensive load and the depleted mixture, the pistons were overheated, they were deformed - and went under the replacement. In weaker versions, return 122 and 125 hp, there were no problems.

tensile chain TRM.

Most of the owners of 1.4 TSI faced with this problem. The material of the chain is considered not too reliable, as a result she was quickly stretched, and the hydraulic tensioner began to live his life.

If the owner ignores the crackle in the open space, it jumps - and then there is already a meeting of the valves with pistons not far.

The GRM chain is declared by the manufacturer as non-servant, but on the fact the chain or its tensioner has to change every 60 -120 thousand km of run.

failure of the System Systems Systems distribution

When the circuit on the engine is stretched and its inspector does not work, as necessary, the gas distribution phases begin to "jump" - the owner feels it for the unstable operation of the motor and the characteristic "diesel" sound of work. Solving the problem - on the service, but you won't call it budget.

circular oil and valves

The burned oil forms coke colors on the valves and the oil worker. This is especially characteristic of those engines that operate in high gears and in aggressive mode.

Hence the need to ensure that the tachometer shooter does not get into the red zone, and carefully operate the motor.

When the oil worker is clogged with coking particles, its bandwidth falls, and the engine threatens oil starvation. Therefore, even the calibrated low pressure lamp in the motor lubrication system cannot be ignored: you may have to remove the crankcase, change the oil and the filter, clean the lower part of the motor.

other problems

The first signs of dying the air conditioner compressor starts to serve already to 100 thousand km. To 130-150 thousand km fails water pump And the hinged equipment - the pulley of the wedge belt, for example.

Operation 1.4 TSI

The most important thing is that the owner of this motor should be performed - his quality service with good consumables. In this case, the engine will not deliver serious problems.

• Experts and experts who work closely with this engine, mark the importance of compliance with the service regulations.
• Like all turbocharged motors, this engine does not tolerate bad gasoline And doubtful motor oil - It is impossible to save on the quality of that and other!
• Menuing oil is recommended every 10 thousand km run. Use only recommended by the manufacturer.

Consumption of oil on the era, provided by the manufacturer, is a liter for 10 thousand km. Over time, it can increase due to the load on the turbine. During normal maintenance, the owners use a maximum of 500 ml of oil on top of the topics.

The turbine itself is quite reliable and can pass 120-200 thousand km without serious interventions.

The fuel injection system in 1.4 TSI also does not cause the owners's complaints. If water does not fall into the fuel, nozzles threaten anything.

TSI engines do not tolerate short trips to the cold. They go to operating temperatureand just do not have time to breathe completely. If you fail to avoid trips to the cold for short distances, at least change the cutting candles once in 20-30 thousand km - to their quality and regulations of the replacement these motors are especially whims.

You can not put cars with 1.4 TSI to transfer without a manual brake - If the car moves back, standing on the gear, it will be a very big risk of a slip of the chain.

A constructively unreliable timing chain should pay attention to the owners - at the very first extraneous sounds from the boost space, you need to go to a hundred. Original cost GBC this engine It is about 3 thousand cu, therefore it is not worth the replacement of the chain. She can stretch after 50 thousand km run.

It is important to listen carefully to outside sounds under the hood, especially after a long parking and after launching "on the cold". If a crash appeared in the engine, try to start a starter machine or "from the Tolkucha" - this will lead to irreversible damage to the CPG.

Motor resource Experts are estimated at 300-400 thousand km - but subject to high-quality service and a certain front of work for 200 thousand km.

TOTAL

1.4 TSI - enough tracked motor with good fuel flow, productive and cultural in work.

But the owner should be carefully related to service, do not save on liquids and consumables and contact the servicemen on the first "call".

Given the problems with the CPG of the powerful first versions of the motor, it is not recommended to select versions with double supervision, 160 and 170 hp

Special attention when choosing 1.4 TSI is worth paying service history and run.
