Technical characteristics of the engine SAKH 1.4 TSI turbo. Are TSI engines reliable? Major problems and weaknesses. Failure of the System Systems Systems distribution

25.09.2017

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. From 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.

VW Golf Highline Bluemotion 1.4 TSI. Price: 1 767 600 r. For sale (with a new engine): Since February 2016

The result of this test for me consists of two well-pronounced components - technical and operational with a philosophical color. I'll start with the first. Engine 1.4 TSI with a capacity of 125 liters. With. who, at first glance, differs from its predecessor only marking and nothing special is in reality absolutely new. Aluminum cylinder block, not cast iron. Lose weight and all drowsing of the turbomotor. As a result, the engine dropped more than 20 kg. Forgive me for the details, but as a motorist was difficult to pass by the "delicious" design solutions. The exhaust manifold, for example, and the head of the cylinder block is a monoblock with a personal cooling circuit. With a cold start, firstly, speeds up the output of the neutralizer to the working mode (which, frankly, does not care much), and secondly, and this is the main thing - the time of heating the cabin during the cold season (!). And further. In mode full power Such a layout allows you to reduce the temperature of the exhaust gases, increasing the resource of the turbocharger. According to the cooling association, the turbine has remembered that during the test of the VW Golf Bluemotion test, when the temperature beyond the board (let's call it), the car has become the mark of 30 degrees, the car began to cool the salon with such a diligence that no tricks could save me from the dwarf stream of ice air. As a result, a marked shoulder and all subsequent pleasures for a month and a half. I do not know, perhaps, out of a thousand versions of the slope of the salon and was safe, but my qualifications did not have enough for its discovery.

But let's go from the theory to practice and from the general to the private. Let's start by S. real expenditure. On the site of the route from Moscow to the border with Belarus (about 500 km), under the fear of the dismissal chamber (average speed of 89 km / h), the consumption of VW Golf 1.4 TSI - 5.7 l / 100 km. In Belarus on an ideal track with a constant (real) speed of 115 km / h -6.6 l / 100 km. In Poland on the autobahn at a speed of 150 km / h (actually 140 restriction, but everyone rushes 150 or more) - 7.6 l / 100 km. In Germany (a lot of repaired sections) - 6.8 l / 100 km. In France, by paid highways (a limitation of 130 km / h) - 6.6 l / 100 km. 3200 km drive through European towns - about 7.0 l / 100 km. If you calculate the average value of the flow rate of VW Golf 1.4 TSI throughout the test for 10 thousand with kilometers gas, then it turns out 7.4 l / 100 km. The earned educated reader will look at all previous numbers and says that somehow it does not work. I agree. But I have not yet indicated consumption in Moscow. And he is 9.3 l / 100 km, and believe me, no disconnected cylinders will help here! After all, if an early early morning (hours in 5), I easily get from the house to work for 35-40 minutes, then the day and three hours may not be enough. And here is how you guess, not in the car.

Geography navigation can be boldly to put the top five, but for the pronunciation of the name in French - solid count!

Finally, my surprise. The first time I was surprised, seeing the price VW Golf Bluemotion - 1,767,600 rubles. Much will be too much, I thought. The second time mentally uttered this phrase, seeing the complete set. There was everything and a little more, except the already described system of disconnecting two cylinders, and this is also with a plus sign! At first, I decided that it was just the so-called democar, where everything is, including absolutely useless systems for us. For example, a car holding system in a busy row or automatic switching of light from a long-distance closeness and vice versa. And then I realized: no one is a democar, but an ordinary alien who accidentally brought to us from the future (perhaps far). Therefore, by the time such cars with their capabilities will become a real need for Russians, the ruble strengthens two times and the price will become very real and massively affordable. But for this we must become Europe.

Driving On the roads of normal quality (even by our standards) gives pleasure Salon With proper ergonomics for urban ride Comfort For four (2 + 2) in the city - "Eight", for two - "dozen". I do not rate on distant distilts, therefore, in the habitat, the total "nine" Safety Everything is in full program. With a tough estimate, you can find fault with highlights on lobby glass With a bright oncoming sun Price Adequate for this configuration, where everything is, and even more necessary Middle score

• The car is functionally solid, well balanced by controllability, with an adequate response in the entire speed range
• Uncomfortable with long distillation (over 500 km). By russian roads especially

1.4 TSI engines, EA111 families
Description, modifications, characteristics, problems, resource

Turbated family engines EA111 (1.2 TSI, 1.4 TSI)the VAG concern was submitted to the public at the Frankfurt Motor Show in the distance. Engine data internal combustion Have a wide range of various modifications, and replaced by four-cylinder atmospheric atmospheric 2.0 FSI.

The new design allowed fuel savings in 5% with an increase in power by 14% compared to two-liter FSI.

The manufacturer describes the main design features of the Motors of the EA111 family of the following list:

• Having versions of 1.4 TSI engine versions with a double supercharge system with a turbocharger and a mechanical compressor that works on low revs (up to 2400 rpm), increasing torque. At the engine speed slightly above idle move The supercharger with belt drive provides pressure of 1.2 bar. The maximum efficiency of the turbocharger is achieved on medium turnover. Applied on engine modifications with a capacity of more than 138 hp;
• The cylinder block is made of gray cast iron, the crankshaft is a wrought steel conical shape, and the intake manifold is from plastic and cools the air of the superior. The distance between the cylinders is 82 mm;
• Head cylinder head aluminum alloy;
• Engine fingers with automatic gap compensation in hydroclap;
• Homogeneous composition of the fuel and air mixture. During the engine launch, high pressure is created on the injection, the formation of the mixture occurs with layers, and the catalyst is heated;
• Chain of the gas distribution mechanism;
• The camshaft phases are adjusted by a stepless mechanism, smoothly;
• The cooling system is a double-circuit, also adjusts the air temperature. In versions of 122 hp and less - intercooler of liquid cooling;
• The fuel system is equipped with a high pressure pump with the possibility of limiting up to 150 bar and adjusting the volume of gasoline supply;
• Oil pump with drive, rollers and protective valve (DUO-CENTRIC).

Based on power aggregate Lies a cast iron cylinder block, covered with aluminum 16 valve head with two distributive treals, with hydraulic components, with a phase inspector on an inlet shaft and with direct injection.

The GDM drive uses a chain with a service life calculated for the entire period of operation of the motor, but in reality the replacement of the timing chain is required after 50-60 thousand km of mileage on dorestayling chains (until 2010 release) and after 90-100 thousand km. on a modified GRM mechanism (after the 2010 issue).

Engines 1.4 TSI families EA111 varies with two degrees of forsing. Weak versions are equipped with a regular turbocharger MHI TURBO TD025 M2 (122 - 131 hp), more powerful 1.4 TSI Twincharger, work according to the compressor scheme Eaton TVS. + Turbocharddv KKK K03.(140 - 185 hp), which practically eliminates the effect of the turboyama and provides substantially more power. In order to understand the main differences between these engines, it is enough to look at schemes their devices:

The main problems and disadvantages of the 1.4 TSI engines of the EA111 family:

1) Tensile timing chain and problems with its tensioner

The most common deficiency of 1.4 TSI, which may appear already during runs from 40 thousand km. The crack in the engine is a typical symptom, when there is such audio support, it is worth going to replace the timing chain. In order to avoid repetition, you should not leave the car on a gear slope.

Drive motor Motors 1.4 TSI EA111 is carried out with a chain. The chain was very short-lived. It must be changed with an interval of no more than 80,000 km. Replacing the timing chain is made with the installation of Remkomplekt. If you need to replace the crankshaft asterisk and the phase management. Why do you have to change the chain? She simply stretches with time. The concern VW vinyl in this supplier of chains - they say, they did it not well enough.

The tension of the timing chain is fraught with its crossroads, which ultimately leads to the death of the motor: the valve strikes the pistons. However, this trouble can be predicted. The fact is that when the chain is unnecessarily stretching, the 1.4 TSI motor immediately after launch rattles and shifts. If a suspicious sound appeared immediately after starting the motor, you should sign up for the replacement of the chain.

However, the chain in the Motor 1.4 TSI can jump and without it stretching. The fact is that the tensioner chain is very unsuccessfully constructed in this engine. The tensioner plunger performs its function - puts forward the tensioner bar - only in the presence of working oil pressure. When the engine is stopped, the oil pressure is absent, and the tensioner plunger does not interfere with the emphasis. Moreover, in the engine 1.4 TSI, the mechanism of blocking the plunger's antihodes is not provided. Therefore, each car owner with a 1.4-liter motor from the VAG concern knows that it is impossible to leave it on the transmission in the parking lot. In this case, the chain will stretch, pushes the bar and the plunger and will literally hang on the architects of the timing. When the motor starts, the circuit will easily jump on 1-2 teeth, which will be enough for the piston to hit the valve.

Schedule Motor Motor 1.4 TSI chain also occurs when trying to start a car on a tow or during clutch replacement. There were cases that after installing a new clutch (both on the MCP and on the DSG), it was necessary to resort to the replacement of the motor, which "died" on the same hundred immediately after turning on the starter. Due to the negligence or ignorance of such a motion feature of 1.4 TSI, people faced problems and when running literally at 10,000 km or through a short time after replacing the timing chain repair kit. If the 1.4-liter motor failed due to stretching the timing chain, it is more profitable to buy a contract unit and replace it.

About how to independently replace the timing chain on the 1.4 TSI motor of the EA111 family.

2) The engine does not pull, the machine does not go, the engine does not spin above 4000 rpm (front turbine)

In this case, the problem is most likely lies in the bypass valve of the tube compressor.

It happens that 1.4 TSI ceases to produce maximum power. What happens this is quite unexpected: the driver accelerates the car, squeezing the gas to the floor on all transmissions, and when the maximum traction is achieved sharply disappears and no longer returns. Also possible symptoms as uneven thrust during acceleration (acceleration of jerks) or the drop in the power of the motor when driving under the hill is also possible. True, if you drown out the motor and start it again, the forces to the motor can return (and may not return).

The reason for such behavior lies in the hitch of the camping valve "Westgate", which is installed in the graduate manifold after the turbine. When engine turnover, and accordingly pressure exhaust gases And the turnover of the turbine wheel, the bypass valve increases, through which the gases go past the turbine wheel. If this valve will open unevenly, eat or will be loosened, then problems arise with the control of the turbine performance (it simply does not create sufficient pressure pressure), which leads to the symptoms described above.

In fact, the turbine itself has nothing to do with it, but it is necessary to replace the bypass valve and its rod. And they come assembled with the hull (both "snails") of the turbine. This is what the flap looks like in the jamble position from the inside:

To make sure that the damper is twisted, it is necessary to open and let it go. She must go back. If she gets stuck in the extreme position, then it is simply clinically there. That's how it should work:

Some put the limiters so that the actuator rod does not reach the extreme position in which the damper clins. But as a rule, even using high temperature lubricantsThe problem is still returned. As a temporary solution for the accumulation of funds to a new turbine - quite, but in one way or another, the turbocharger will have to be changed in this situation. Remkomplekt in the form of a graduate manifold 03C 198 722. It costs as much as all non-original turbocharger BorgWarner.Therefore, it makes no sense to change only a collector not particularly. That's how he looks like a repair kit Turbs 03C 198 722. (gaskets and wrenches are ordered separately):

But it looks like one of the examples of the opening limiter wicket of Westgate:

3) Troit engine and vibrates on cold

Indoor 1.4 TSI EA111 engines When cold start, start the engine and work with diesel terrain. In fact, this is their support mode of work, during which an increased portion of fuel is injected into the cylinders. It is necessary for accelerated warming up the catalyst hotter exhaust gases. "Trojection" disappears as the engine warms.

4) MACHINE

Motor 1.4 TSI EA111 consumes engine oil in much more modest volumes than its older brother 1.8 TSI or 2.0 TSI. However, this does not cancel the need to monitor the oil level. It is recommended to get the probe weekly and control the level.

It is also recommended to turn off the Motor 1.4 TSI to work for about a minute to idling. During this time there will be a cooling of the exhaust manifold and the parts of the turbocharger. After stopping the engine, a recycling pump will work for a while, built into the engine cooling system. It can work some time after turning off the ignition, running the cooling fluid over the entire circuit of the cooling system. Therefore, do not be afraid when, stopping the motor, you leave the car, and noise comes from under the hood.

5) demanding quality of fuel

Of course, any motors prefer high-quality fuel, but the story is special. Due to poor-quality fuel, a nagar on fuel nozzles occurs, which at the motor 1.4 TSI EA111 are located in the combustion chamber - the injection is immediately. Nagar on the nozzles changes the flow of spraying of fuel, which can lead, with the most unsuccessful coating of circumstances, to the trough of the piston.

In general, the 1.4 TSI EA111 motor pistons, which for VW produced MAHLE, rather fragile. And the gasoline injection pressure is very high. And if in the chamber of the combustion of this engine will fall poor-quality fuel, the inevitable detonation will very quickly break small, light and thin-walled pistons. The 1.4 TSI motor refueling with poor-quality fuels quickly leads to the burnout of the pistons and the destruction of the walls of the cylinders. In addition, nozzles and even fuel pump come from low-quality fuel.

Also on poor-quality gasoline, the intake valve of the 1.4 TSI motor valve is covered by Nagar. The case is in a direct injection that is not capable of cleaning the inlet valves by the flow of fuel. On engines with distributed injection passing in composition fuel mixes on the leg of the valve and its work surfaces, most Nagara washes off and he burns in the chamber. But on Motors 1.4 TSI with their immediate injection, the Nagar is constantly accumulated on the "cold" intake valves. The critical amount of Nagar accumulates to a run of 100,000 - 150,000 km. As a result, the valve cease to feel tightly to their saddles, compression is reduced, and the motor begins to work unevenly, loses power and spend more fuel. Therefore, a rather common procedure for Motors 1.4 TSI is the removal of the head of the block, its complete disassembly and cleaning of paths and valves.

6) leaks antifreeze (coolant leakage)

Usually the leakage of antifreeze on motors 1.4 TSI EA111 is developing gradually: first to attach once a month (approximately "from an almost empty tank to a max level"), then the problem becomes more annoying, and the topping is already required "once every 2-3 weeks". At the same time, visual herds are not visible anywhere (running forward, I will say that this is due to the fact that the runaway antifreeze immediately evaporates from contact with the hot parts of the issue).

To diagnose, you need to remove the thermoe screen from the turbine, which will allow you to make the primary visual inspection. Usually in this situation on the connection of the hot part of the release and downpapp there are traces of "scale".

At the same time, in the very turbine of traces of antifreeze, there is no, since it has time to evaporate from contact with a very hot supercharger body. Therefore, to search for leaks should be moved above in the inlet, where there is an intercooler with liquid cooling. That is, it uses antifreeze for cooling upward air, which means there may be a refrigeration fluid leakage. There is this wonder-cooler behind the intake manifold, between the motor shield and the engine.

At an early stage, you can do a simple replacement of the cooler itself, which has given a flow, but if you do everything in mind, and if the case is already running, it is necessary to remove the CCC, to produce its cleaning and complete defects, as antifreeze in the combustion chamber leads to incorrect burning Mixtures and related consequences.

7) The turbine drives the oil in the intake manifold (while the turbine is proper)

It happens so that increased flow Oils are not connected with fuzzy through a piston group, but due to the fact that the turbine drives the oil in the intake manifold. At the same time, the diagnosis of the turbo-compressor itself does not identify problems. As a result - throttle valve And the intake tract is covered with oil, and the air filter is clean.

See how the oil from the turbine will fall, you can remove the suitable air and the box air filter. On the speed of idling most likely everything will look normally, but with an increase in turnover over 2000 from under the cold impeller, oil will begin.

In this case, most likely, the ventilation system of crankcase gases is incorrectly operating, or the oil separator is clogged, which is under the cover of the timing mechanism. There are others possible reasons This behavior of the turbine, which are described in a separate topic.

8) inlets of the bell part of the turbocharger has traces of oil fogging

Seeing the traces of oil fogging on the inlet from the air nozzle, which brings the air from the air filter to the cold part of the turbine, do not get enough for his head - everything is in order with the turbine, but the sealing ring that is on the junction of the nozzle and the turbine must be replaced. At the same time, the pipe itself needs to be finalized and remove traces from the injection mold on plastic - sowing, through which oil pairs run away (shown by arrows).

9) Appeals antifreeze through seals in the turbine cooling system

The problem is though a kopeck, but still the smell of burner antifreeze in the cabin can slightly scare the owners of motors 1.4 TSI EA111. The thing is that from high temperaturesThe seals in the cooling system of the turbocharger TD025 M2 come into disrepair and begin to pass the cooling fluid to the outside of the turbine. Antifreeze is burning, and in the process of its evaporation there appears specific nasty smellwhich enters the salon through the air conditioning system. It is necessary to look at the presence of antifreeze on the turbines, greenish divorce from the coolant on the tubes.

To eliminate this unpleasant jamb, you just need to replace the VAG sealing rings WHT 003 366. (2 pcs). And the replacement technique is described in the appropriate topic.

Engine resource
1.4 TSI EA111 (122 - 125 hp, 140 - 185 hp):

With timely service, the use of high-quality 98th gasoline, calm operation and normal attitude towards the turbine (after the movement to work for 1-2 minutes), the motor departures for quite a long time, resource engine Volkswagen. 1.4 TSI EA111 is about 300,000 km, thanks to a strong cast-iron cylinder block and reliable GBC.

At the same time, it is impossible to forget that the oil should be high quality and vary at least than 10,000 km of run.

1.4 TSI EA111 (140 - 185 hp):

On the twincharge engines, the situation is more interesting, here the stage 1 firmware can be raised power up to 200-210 hp, while the torque increases to 300 nm.

You can not dwell on the achieved and go further by making the standard Stage 2: Chip + Downpipe. Such a kit will give you about 230 hp. And 320 Nm of the moment, it will be relatively reliable and riding forces. Further climb does not make sense - reliability will significantly seek, and it's easier to buy 2.0 TSI, which will give 300 hp

The first thing that the potential car owner is watching when buying is the optimal combination of engine and transmission. Not all drivers seek to get the most powerful motors, and automakers understand this by offering various variations of engines to purchase. One of the European Engine Variations in Russia car brands It is 1.4 TSI motor. Such an engine is installed on cars Skoda., Audi and Volkswagen. As part of this article, we consider what advantages and disadvantages of the 1.4 TSI engine, as well as its resource.

Based on the block of motors with a volume of up to 1.4 liters, a new series of 1.2 and 1.4 liters of EA11 series presented (do not look for simple logic in numbering). Motor power was 105-180 hp The base for new engines was atmospheric models of AUA / AUB with a volume of 1.4 liters, made using a new modular layout of attachments of attachments and with chain drive timing. Motors received the designation of TFSI / TSI, as they were equipped with a direct fuel injection and superimposed. Especially note that there is no difference between fuel systems TFSI and TSI No, these are just two marketing names of the same for Audi and Volkswagen models. Motors 1.2 liters of this line are very different from 1.4 L. engines. They have another eight-glove GBC and a slightly different block, another piston group, and there are no high-known options.

Characteristics 1.4 TSI

Engine reliability 1.4 TSI

A series of low-volume Turbomotors EA111 (1.2 TSI, 1.4 TSI) gained widespread in 2005, thanks to the popular Golf 5 and the Jetta sedan. The main and initially the only engine was 1.4 TSI in various modifications, which was called to replace atmospheric 2.0 fours and 1.6 FSI. The power unit is based on a cast-iron cylinder block, covered with an aluminum 16 valve head with two camshafts, with hydrocompensators, with a phase inspector on the inlet shaft and with direct injection. The GDM drive uses a chain with a service life designed for the entire period of operation of the engine, but in reality the replacement of the timing chain is required after 50-100 thousand km. Let us turn to the most important thing, and most importantly in TSI engines it is, of course, reducing. Weak versions are equipped with a regular turbocharger TD025, more powerful 1.4 TSI Twincharger and operate according to the EATON TVS + turbocharger compressor KKK K03, which practically eliminates the turboyama effect and provides significantly more power. Despite all the manufacturability and advanced EA11 series (Motor 1.4 TSI, the repeated winner of the "Engine" contest), in 2015 it was replaced by an even more advanced series of EA211 with a new, seriously changed, 1.4 TSI engine.

Problems and disadvantages of 1.4 TSI engines

Progress in place is not worth it, and in the 10th of the XXI century, the turbo engine with the immediate injection will not surprise anyone, the technologies are gradually being worked out, the mistakes are corrected ... And the motors of the next line of the EA211 came to replace the EA111 - most of them are equipped with most modern machines concern Volkswagen.. Judging by the first reports of "Stroy and" two-anniversary "from among the owners, as well as by the reviews of the masters, the series turned out to be more successful. And about it Next.

Volkswagen engine resource and what differs from the predecessor 1.4 TSI EA211

1.4 TSI new Series EA211 (1.0 TSI, 1.2 TSI) came to replace the Popular 1.4 TSI EA111 series and is a seriously finalized practically new Motorlocated at an angle of 12gr. Back. In the power unit, the bottom was completely replaced: the cylinder block is now aluminum with cast-iron sleeves, the diameter of the cylinders decreased by 2 mm, now it is 74.5 mm, the crankshaft is replaced with a lighter and long-point (80 mm stroke, there was 75.6 mm), light connecting rods are used. This is the entire 16-valve head with two camshafts, but unlike the past generation, the CFC is deployed 180g. And now the exhaust manifold is located behind, the reservoir itself is now integrated into the head. Motor 1.4 TSI is equipped with hydrocompensators, the direct fuel injection system is applied. At the 122-strong version, a phase storage was installed on an inlet shaft, a modification with a capacity of 140 hp, equipped with phase beams and inlet and on the release. Changes have also occurred in the TRM drive, now instead of the chain, the timing belt is used, which must be checked every 60,000 km. Here is a new two-king cooling system, and at a modification of 140 hp. A system for disconnecting two ACT cylinders is available. In addition to everything, this motor is equipped with a turbochargedwood system, with an intercooler built-in inlet collector. On the different modifications Turbines are distinguished by: a capacity of 122 hp Uses the turbine slightly smaller (with a pressure of 0.8 bar), 140-strong modifications, respectively, more and the pressure here is 1.2 bar. Motor control lies on the Bosch Motronic MED ECU 17.5.21. This engine is released today, but since 2016 it is changed to a new 1.5 TSI.

Problems and disadvantages of engines VW 1.4 TSI

Important: When buying a supported car with an engine 1.4 TSI, it is necessary to determine how often the owner has changed the oil in the motor. If he did it less often than 1 time in 10-12 thousand kilometers of run, and the total mileage of the engine exceeds 60-70 thousand, it is better to give up the purchase of such a car.

It is also worth noting that the 1.4 TSI engine is not very quickly warming up. Therefore, by car with such an engine, it is better to eliminate short trips during the cold season. If such trips are performed on a regular basis, the motor is constantly subjected to temperature drops that negatively affect its operation. In the case when the short-term operation of the vehicle with an engine 1.4 TSI cannot be excluded, it is recommended to change the candles more often.

In 2007, the Engineers of the German automotive company Volkswagen on the basis of the Hatchback Volkswagen Golf was designed fundamentally new car - VW Tiguan. Thanks to the impeccable reputation of the progenitor, the SUV in a short period of time won universal recognition. True, according to the results of 2014, Tiguan lost two first positions on the pedestal of popularity to their competitors Honda CR-V And Toyota RAV4. Already in 2015, the manufacturer announces the start of the production of the second generation of the SUV. The exclusive novelty was able to breed the market segment.

Today the car is collected not only in Germany, but also in Russia, in the city of Kaluga. The German company has increased its power potential on the domestic car market, thereby heated additional interest in the SUV from the Russian buyer. Before purchasing an expensive car, it is advisable to get acquainted not only with his operational properties, but also the indicators of reliability and durability. Next, we define what is the actual engine resource on Volkswagen Tiguan 1.4, 2.0.

A variety of motor line

Volkswagen Tiguan motor gamma represents turbocharged power units with a working volume of 1.4 and 2.0 liters. Engine 1.4 TSI with a capacity of 122 and 150 hp Also installed on. Gasoline engines are excellent beautiful technical characteristics and a large enough resource. As practice shows, power plants from the VW Tiguan line are capable of passing 300 or more than thousands of km. Motor 2.0 TSI is made of a cast iron block of cylinders and an aluminum head.

There are several of its modifications that differ in their rated power - 170 and 200 horse power. Also the buyer is available to choose a diesel equivalent. Cardinal structural differences between engines do not detect. The difference lies in the fact that the 170-strong version is functioning due to the BorgWarner KO3 turbine, and KO4 is installed on a more powerful analogue.

Some construction features Motors VW Tiguan:

• Degree of compression 10.5;
• Number of valves - 16;
• The presence of a DOHC / belt;
• Ecological class corresponding to the norms of Euro-5.

The first generation of "Tiguan" was equipped with a 6-speed hydromechanical machine, and the subsequent generation had acquired a 7-speed DSG robot. The transmission of the SUV is known not only to high-quality assembly, but also silent work. At the stage of overclocking the car, engine operation is muted, and on the cruise velocity only noise published by tires.

How many "walks" the engine on Volkswagen Tiguan

In order to understand what the actual motor resource on Volkswagen Tiguan, it is necessary to figure out more in more detail. constructive features. The bulk of the owners of modification with a 1.4-liter engine complains about the designs of the designers in the strength piston group. In particular, the piston itself, which due to excessive loads and high temperatures fails prematurely. The first problems with this structural element of the power unit may occur at the turn of 100 thousand km. Also at this stage, it is advisable to follow the state of the timing chain. Turbodiesel 2.0 TDI instead of the chain has a belt. Over the state of the TRV drive must be monitored in the most thorough way. The break of this element leads to unpleasant consequences - The valve is bent. As you know, repair and maintenance of German SUVs - the pleasure is not cheap.

When passing the first 150,000 km, an increased oil consumption is observed - oil rings or valves should be replaced. Diesel 2.0-liter engines won in terms of actual resource from gasoline analogs. But it is worth saying that problems with the pump in some cases cannot be avoided. The reason for this becomes low-quality fuel. Professionals are recommended to constantly monitor the status of the pusher of the fuel pump, it is best to carry out a comprehensive diagnosis after every 20-30 thousand km.

Total Next: 1.4-liter petrol motor It is capable of passing about 300 thousand kilometers of the path, subject to proper and regular service. Diesel analogue up to the first overhaul undergoing over 350,000 km.

Review of owners about the resource of the power unit

Both turbomotors are qualitative and reliable, differ in high speed characteristics, but extremely demanding on the quality of fuel refilling and motor oilSensitive to the coolant. For all three components, it is necessary to closely, otherwise they will have to be invested in expensive repair of the car. We now turn directly to the reviews. vOLKSWAGEN Owners Tiguan, experienced by determining the duration of the freight work of the main power unit of the car.

Engine 1.4.

1. Mikhail, Voronezh. It remained unhappy with the acquisition of a representative of the German car industry with a 1.4-liter engine. The motor does not cope at all with his tasks, Volkswagen Golf with the same engine was several times in beyrea. Plus to everything dubious build quality and a very funny resource. I have Tiguan 2010 and for all this time in repair invested the amount of the equivalent cost of the car. From constant detonations on the pistons break the edges under the rings. Very demanding on the quality of the fuel car.
2. Maxim, Yalta. The SUV as a whole was satisfied, but there is one big but. 1.4 TSI engine frankly speaking too weak and unreliable. For such a Mahina, a minimum is needed 1.6 liters and not 150 hp In the morning the car has to start as our AvtoVAZ. I refuel at LUKOIL AI-95, as recommended by the manufacturer. The chain is simply terrible, flew, without passing 80 thousand km. The engine is constantly gluch on traffic lights, at any time he could start tall. In general, I sold this car and began to sleep well.
3. Stanislav, Vladivostok. I go to Volkswagen Tiguan since 2009. When 110 thousand miles came up to the mark, problems with chain began. I quickly replaced, no longer had no breakdown. For the year behind the wheel of an SUV - only positive impressions. Those who love to put pressure on the gay from the start, this car is definitely not suitable. With such a mass and power, the circuit flies at times.
4. Egor, Moscow. Driving from 2015. Screw during this time 70 thousand km. The warranty changed the thermostat, and the crack was formed in the intake manifold. With the launch during the frost there are no problems, the suspension of the highest level. Motor resource 1.4 TSI is too dependent on the quality of gasoline. Any unsuccessful refueling can turn into trouble. Too late I was opened by the mystery - the aluminum unit and the plasma spraying "live" with our combustible 100 thousand km.

Power unit volume of 1.4 liters of good in its characteristics. However, it is too dependent on the quality of fuel refilling, maintenance of maintenance and many other external factors. Not the most successful development of German engineers, which is confirmed by the reviews of the former and current owners of Volkswagen Tiguan 1.4.

Engine 2.0

1. Nikolai. Urengoy. Since 2008, we exploit the German SUV with a diesel engine. When passed, 170,000 km decided to replace the timing belt with rollers and pomp. Now the car starts even better even at -30. On the notes of drivers: diesel win in terms of resource at a gasoline analogue under the same operating conditions and equal working volume.
2. Sergey. Moscow. During the choice of VW Tiguan, paid great attention to the quality of the engine. After reviewing a large amount of information, it came to the conclusion that the 2.0-liter motor resource is significantly higher, which is less voluminous analogs. In practice, everything was confirmed - the chain for the first 200 thousand km does not submit any signals. The main thing is to refuel on proven gas stations and use certified oil.
3. Alexey, St. Petersburg. I have a car 2017, diesel 2.0. Before buying, communicated with competent people on the reliability of Tiguan's motors. People said the chain resource is about 300 thousand km, that is, almost to the first capitals. The turbine passes even more, made everything on high level. Much depends on the quality of the consumables themselves and planned service Auto.
4. Matvey. Cheboksary. Ask the experienced owner of VW Tiguan, which modification of reliable, it will answer you - two-liter. I myself personally saw the car past more than 300 thousand. The resource depends on the driving style, the first 200 thousand km in general pass without any problems with adequate driving.

Many car owners agreed in a single opinion that the 2-liter power point It is more reliable and resistant to unfavorable operating conditions. Numerous studies also confirm the fact that in practice the Volkswagen Tiguan 2.0 engine resource is more than 300 thousand kilometers.
