Determination of turbine overflow by logs, TDI engines, etc. (rus.) Photo report
The most pressing problem in turbocharged engines is the occurrence of an overflow. This is especially true for diesel engines. the formation of soot in the exhaust gases leads to its rapid accumulation inside the turbine and wedging of the geometry. First, let's try to figure out how the inflation pressure is regulated, and then let's look at what the blowout looks like in the logs.

The fourth generation Audi A4 was presented at the end of 2007, and in 2008 its mass production began. In 2012, the model underwent restyling, and in 2015, there was a generational change.

The Quartet has a wide range of various engines: 1.8 TFSI (120 and 160 HP), 2.0 TFSI (211 HP), 3.2 FSI (265 HP), 2.0 TDI (120, 143 and 170 hp), 2.7 TDI (190 hp) and 3.0 TDI (240 hp).

The most widespread are the 1.8 TSI and 2.0 TSI turbo engines, and with them the problems that undermine the reputation of VAG engines. The most common trouble with "inflated" motors is the increased oil consumption, sometimes reaching 1-1.5 liters per 1000 km. Unhealthy appetite grew by 20-40 thousand km. The reason for the "maslozhor": unsuccessful design of pistons and rings. Authorized services recognized the problem after a control measurement if the oil consumption exceeded 0.5-0.6 liters per 1000 km. In this case, the piston group was replaced. As a rule, after the repair, the appetite of the motor returned to normal. Those who have not looked into the service, eventually have to change defective parts at their own expense - from 40,000 rubles.

Engines with a modified piston group began to roll off the assembly line from the 22nd week of 2011 (i.e. from May 2011). But they, no, no, and they begin to eat up oil after 100,000 km. In June 2013, they began to install modernized gen.3 turbo engines, in particular the CJEB and CNCD. They no longer suffer from maslorezor.

The oil separator can also contribute to increased oil consumption - due to a ruptured diaphragm or a seized valve (cleaning briefly revives the oil separator). The cost of a new unit at dealerships is about 8,000 rubles, in ordinary auto parts stores - about 4,000 rubles.

In modernized gen.3 turbo engines, the thermostat often fails.VAG prescribes to replace the entire unit at a cost of 15,000 rubles, but you can get off by replacing a cheaper emergency thermostat - only 600 rubles. Most often, it is he who becomes the source of problems - a wedge or opens early.

Another serious, but less common malfunction is the timing chain jump to one or more links. Typical for engines assembled before 2011. Symptoms: crackling, clatter, rattling when starting a cold engine, or the engine simply won't start. Causes: chain stretching, failure of the chain tensioner and phase shifter shut-off valve. To prevent possible problems, the manufacturer held a campaign # 15D6 to replace defective units.

2-liter turbodiesel Audi A4 is reputed to be quite reliable.

With high mileage, a loss of traction is possible due to a clogged particulate filter. The filter has a regeneration function, which is activated by a command from the sensors when the clogging is more than 40%. Due to sensor failure, the self-cleaning program does not start and the filter becomes clogged. Its restoration is impossible. A way out of the situation: removing the particulate filter and flashing the engine ECU. The cost of such work is about 9,000 rubles.

The turbodiesel uses a timing belt drive with a replacement interval of 180 thousand km. In Russian operating conditions, it is better to reduce this period to 120 thousand km. The cost of the timing kit is about 7 thousand rubles, and the replacement work: about 25-30 thousand rubles from official dealers and 8-10 thousand rubles in ordinary services.

After 250-300 thousand km, the hexagon of the oil pump drive may wear out. The pump performance drops, which leads to accelerated wear of the turbocharger and the engine itself. A new balancing shaft module with an oil pump costs over 90,000 rubles. Many services have learned to restore the assembly by replacing the re-machined hexagon.

The rest of the engines are rare, but do not have any serious problems.

There are two more "weak points" in all Audi A4 engines. This is the current pump. The problem usually comes out after 60-90 thousand km. The cost of a new pump of the cooling system at the "officials" is about 8-10 thousand rubles, and work on its replacement from 2 to 6 thousand rubles - depending on the engine. A more budgetary option is to replace only the pump impeller at a cost of 2,000 rubles. Another equally common malfunction is the failure of the engine hydraulic support when the mileage is more than 40-60 thousand km. The cost of a new support from dealers is about 10 thousand rubles.

Transmission

The engines were paired with a 6-speed "mechanics", a continuously variable variator Multitronic, a classic "automatic" Tiptronic (all-wheel drive versions with 3.0 TDI and 3.2 FSI) and a 7-speed S-tronic robot (all-wheel drive with 2.0 TFSI).

Manual and automatic transmissions are the most reliable on the list. The variator is considered more reliable than on its predecessor, but sometimes there are calls to the service with a mileage of more than 80-100 thousand km. Most often, you have to complain about tremors, which are almost impossible to eliminate.

The most capricious was the robotic gearbox. Common Complaints: Twitching and hard shifting. The problem worsened to 40-60 thousand km. Dealers re-flashed the box's ECU and changed the clutch, and in case of repeated calls, they changed the mechatronics (about 30 thousand rubles). At the end of 2013, the problematic node was finalized.

The all-wheel drive versions feature a reliable transmission. There were no systematic complaints about the work of the all-wheel drive.

After 200-250 thousand km, it may be necessary to replace the two-mass flywheel (it starts rattling or knocking), the cost of which is about 30,000 rubles, and the replacement work - about 6,000 rubles. The clutch serves more than 200-250 thousand km (from 15,000 rubles per set).

With the advent of cold weather, when driving through irregularities behind, knocks begin to be heard from time to time. The source is depreciation struts, which often begin to leak even after the mileage is more than 30 thousand km.The suspension arms are capable of overcoming the milestone of 100-120 thousand km. But it was not without a black sheep: the front lower levers have to be sentenced to be replaced after 50-80 thousand km due to wear of the ball joint.

Front wheel bearings often give up after a mileage of 50-80 thousand km. Original bearings in official services are available for 6 thousand rubles, on the side - for 3-4 thousand rubles. The cost of work on their replacement is about 1.5-2 thousand rubles. After 60-80 thousand km, a rupture of the anthers of the external "grenades" of the CV joint is often found. The cost of the boot is about 700 rubles, and the replacement work is about 1-1.5 thousand rubles.

Sometimes there are steering rack leaks. There are frequent cases of knocking on the slats after hitting a deep pothole at high speed. The cost of a new rail is about 60-70 thousand rubles.

After restyling, they began to install rails with a built-in electric amplifier. The amplifier often failed after 20-60 thousand km - more often in cold weather. In rare cases, the owners managed to get off with a software update. VAG ordered to change the steering rack assembly. The cost of such a procedure from official dealers is 200,000 rubles! A restored rail can be purchased for 30,000 rudders, but it sometimes fails after six months. The original site on the side is available for 120,000 rubles. Unfortunately, few people still know how to bring the rail to life.

Body and interior

Some Audi A4 owners were puzzled by paint peeling on the front fenders along the edge of the arches on cars from 2008-2010. There are few such cases - perhaps there was a manufacturing defect (marriage in painting).

Most surprising are the front optics, which work like a vacuum cleaner: the presence of dust and dirt inside is a common occurrence. It penetrates there through the ventilation ducts, the filters of which do not cope with their task. Folk remedy: a piece of foam rubber in a tube. There is also clouding of optics and fog lights. With a run of more than 40-80 thousand km, the motor of the gas tank flap lock may stop functioning.

Squeaks in the Audi cabin are rare. Troublers can dwell in the rear parcel shelf or door trim.

On the Audi A4 2008-2009, over time, the MMI display starts to glow dimly. Cause: CCFL backlight burnout. With a mileage of more than 100,000 km, there are problems with the heater motor (about 10 thousand rubles). Sometimes the driver's door lock fails, and in winter the Keyless keyless entry system is often "buggy".

Let's summarize briefly. The Audi A4 B8, like most VAG models, played a knockout game. The reputation was significantly tarnished by the TSI series engines, the S-tronic robotic box and weak suspension elements.

A month ago, we completed a very interesting project Audi A4 B8 quattro, and the car was successfully run-in!

2009 car was purchased in America and brought to Russia in March of this year.
With a mileage of 62,000 km, there were many problems with the engine:
- Jumps in revolutions at low speeds
- Oil splashes under the hood
- Black smoke
- Huge oil consumption (about 5-6 liters per 1,000 km)

We have carried out a full car diagnostics.
Verdict - engine bulkhead.
However, we did not limit ourselves to standard work - we assembled a sports engine for everyday driving:
- Forged pistons, forged connecting rods, sport liners
- Editing cylinder head planes, new valve seals and guides
- New pallet for internal combustion engines
- New standard turbine
- Complete re-sealing of the motor
- Replacing the timing mechanism
- Catalyst removal
- Installation of a more efficient intercooler in a regular place

The second generation A4 appeared on the market in November 2000 as a Sedan. A year later, the AVANT and Cabrio models appeared on the market. The sports version was introduced in 2002.

The body of the second generation A4 has increased compared to its predecessor: in length by 69 mm (4547 mm), in width by 33 mm (1766 mm), and in height by 13 mm.

Gasoline engines - in-line four-cylinder or V-shaped six-cylinder (eight-cylinder on S4 models) with electronic control.

Diesel engines are in-line four-cylinder or V-shaped six-cylinder.

All engines are water-cooled and located in the engine compartment along the vehicle.

Available in front-wheel drive or all-wheel drive "Quattro" models. All-wheel drive models are equipped with a Torsen center differential with automatic locking.

Depending on the configuration, a fully synchronized 5 or 6-speed manual transmission is installed, or AT (Tiptronic with a dynamic DSP switching program or Multitronic with a dynamic DPR control program).

Front suspension - independent, four-link McPherson with coil springs, telescopic gas shock absorbers and a tubular stabilizer bar. The bridge beam is attached to the body on rubber-metal supports.

The car is equipped with an electronic anti-skid system (stability stabilization - ESP), which combines the anti-lock brakes (ABS), traction control (ASR), electronic differential lock (EDS) and brake force distributor (EBV) into a single network. Installed emergency brake booster (BAS).

The basic braking system is hydraulic, dual-circuit with diagonal split and dual booster. Anti-lock braking system (ABS) with electronic brake force distribution (EBV) with vacuum booster.

Brakes - disc, ventilated on the front wheels.

Everyone knows the reliability of a car brand like Audi, regardless of the model. But no matter how reliable the car is, during operation you have to change certain parts either at the service or on your own. There are many such car owners who repairing Audi A4 with their own hands... Someone may just like to do something on their own, but for someone the services of the service seem too expensive. Basically, attention has to be paid to the car's suspension, the fuel system, and other little things. Some even after an accident restore cars on their own.

The main thing to remember when repairing an Audi A4 with your own hands is that all actions are performed correctly, and then you do not have to contact the service and pay money. Below we will consider some of the car malfunctions, in particular, the repair of the ABS unit and the headlight auto-corrector sensor.

The ABS unit may not work for various reasons. It can fail completely and it will need to be replaced, someone buys a car with a no longer working unit and has to be repaired. For those who have no experience in working with trace elements, it is better not to go into the block, because you can make it even worse. If the ABS indication on the panel is off, we start looking for the problem. You need to short-circuit two wires - yellow / red and brown and unsolder them. After that, the light starts to burn. But even after that, it’s impossible to go in like a lump. The unit itself needs to be repaired.

To do this, you need to remove the front left wheel and wheel arch liner. Next, the washer reservoir and hydraulic fluid are removed. Two connectors are removed - from the block itself and from below. It is necessary with the help of T-20 to unscrew 6 bolts and remove the ABS block. As a result, we have the electronic part of the unit in our hands. Next, you need to open it with a construction knife. Inside, you need to find two thin silver wires. Usually there is poor or no contact in this place. Possible oxidation must be removed from the contact points of these wires. To restore contact, a thin copper wire is taken and soldered to the pad from the connector side. Silver wires are tinned.

Next, you need to move the copper wire to the silver one and solder them together. The remainder is bite off in pieces. Then the block must be sealed back, you can use hot melt glue. After that, it is installed in the reverse order and checked by a vag-lump.If it is clear with the ABS unit, then sometimes the headlight auto-corrector sensors on the Audi A4 can cause trouble. In most cases, these sensors fail due to condensation.

Although Hella is one of the best, if not the best manufacturer of optics, it still doesn't take very good care of moisture protection. This means that the board is not varnished. Although all the joints are dense, moisture, nevertheless, is formed there. There is only a small hole in the housing to equalize pressure with temperature changes. Perhaps moisture gradually penetrates through this hole. As a result, after opening the case, moisture is observed inside.

All car owners of Audi cars and in particular the Audi A4 Good day. Today I will try to tell you as clearly as possible about the operation and repair of the Audi A4 car. Everyone knows the high quality of German cars, but still, regardless of the brand, from time to time you have to think about buying certain parts, replacing consumables, etc. So that your car does not cause trouble, keep an eye on it, take the necessary maintenance measures on time and your “iron horse” will continue to delight you for a long time.

In order not to beat around the bush, I'll get straight to the point. Those who are in the subject know that the Audi ay4 has been refined, changed, improved from generation to generation. All new systems appeared in the equipment that endowed the car with safety, ease of control, etc. To date, many electronic systems have been implemented in the Audi A4 and it is really comfortable and convenient to operate this car, although I have no doubt that there will be those who will have something to complain about. So, about the exploitation.

Power unit... The engine, without exaggeration, is the heart of any car and if it works intermittently, then there is no need to talk about any comfortable handling. In gasoline engines of the Audi A4, oil must be changed every 15 thousand km. The procedure is carried out together with the replacement of the oil filter. In diesel engines, the oil must be changed every 7 thousand km. So that there are no troubles and any questions in the future engine oil should be used only that recommended by the manufacturer. It is clear that not everyone adheres to this. However, this should not be forgotten.

In addition to oil, it is important to remember about the timing belt, which must be replaced every 60 thousand km. Yes, Audi recommends changing the belt after 120 thousand km, however, there are cases when it broke off at 70 thousand km. I think that changing the belt will still be cheaper than repairing the engine later if it breaks. An important point if you have become or want to become the owner of such a car as Audi, and not only Audi, is the availability of quality service. Now there are a huge number of services, but finding a decent one is a problem. Why am I talking about services? The fact is that you can meet many owners of the Audi A4, who, during the operation of this car, are simply unhappy with them because of the problems that arise. So before buy a used car find normal service and diagnose the machine. And pay more attention to cars with diesel engines. In the event of problems, the repair of such a unit will not be cheap, and besides this, again, there will be a problem with finding a quality service.

Gear boxes... On the topic of repair and maintenance of the Audi A4, of course, it is worth mentioning the checkpoint. If we recall the first generation of the Audi A4, then these cars were equipped with an automatic machine, mechanics and tiptronic. Already in the next generations, a multitronic variator was offered. As you know, initially, he did not particularly please the owners with his reliability, but gradually the design was being finalized and becoming more reliable. As for the automatic and manual transmissions, in principle, they do not cause any special problems. What you should pay attention to is changing the oil every 50-60 thousand km.and those who have come across this procedure know that the cost of oil is quite high. In addition, on machines equipped with mechanics, it is likely that the clutch will need to be replaced when the mileage is over 120 thousand km.

Quattro all-wheel drive... In principle, there is nothing negative to say about the all-wheel drive system. It is quite reliable, but, nevertheless, after 200 thousand runs, you may have to think about repairs.

Suspension... Since we are talking about the operation of the Audi A4 in Russian conditions, then with a mileage of about 30 thousand km. you can observe the backlash of the hinges of the lower arms. The upper levers take longer to take care of and you have to think about replacing them at 50-60 thousand km. mileage. The weak elements of the suspension include the old-style anti-roll bar struts. They should be changed every 15-20 thousand km. Old-style racks are meant before 1997. After that, this suspension element has become much more reliable. For shock absorbers - they have to be changed every three to four years. You can assess their condition by visiting the service. In general, the suspension of the Audi A4 should be devoted to a separate article, which I will try to do in the near future.

With regard to the suspension, I would like to note that on all-wheel drive audi a4 the design is somewhat more complicated than on a front-wheel drive car. However, this does not diminish the number of fans of the Audi A4 quattro. All the same, all-wheel drive has significant advantages. But telling that one thing is important to try. Perhaps this is the main thing that I wanted to describe about the operation and repair of the Audi A4 car. I hope you find this article useful and you will at least generally know when and where to look for timely service. Good luck on the road!

The first generation of Audi A4 vehicles are very comfortable and reliable vehicles. Unlike its “ancestors” - the Audi 80 - this model range is more sporty and more stable on the road. The cars are beautiful, despite their relatively old age, they have a modern appearance. Of course, the Audi A4 is not without its drawbacks. Consider the most vulnerable and weak points of these cars.

What is the problem? Rots. The presence of a large number of mechanical defects. The Audi A4 of the first generation, as in subsequent models, has a low seating position. A large number of dents on the bottom are common. In addition, the underbody rots much faster than the rest of the body. Why? Most likely, the manufacturer either used insufficient quality metal for this part of the machine, or used ineffective chemicals in its preparation.
Before buying a car, be sure to drive into the overpass. A mere visual inspection is not enough. You need to lightly knock with a hammer on bends and flat areas of the bottom. The most rusty and rotten places will show themselves. At the same time, you can see if the shields are too deplorable.

The turbine is disease Audi A4 B5... What is the problem? On average, the service life of a turbine on an Audi A4 is about 100 thousand km. The price of a spare part is at least $ 200. Plus work. A malfunctioning turbine will reduce the power of the vehicle. This is especially noticeable during overclocking. Fuel consumption increases. The machine may draw up a large amount of oil. The motor, especially at high revs, emits side sounds - a slight whistle, grinding, uncharacteristic noises. Depending on the type of breakdown, the color of the exhaust gases changes. If the turbine is defective, the smoke from the exhaust pipe can be blue, black or milky white. Proceeding from the fact that Audi A4 B5 is cars with age, then there will be problems with turbines.

How to check it yourself? It is necessary to remove the branch pipe coming out of the turbine. If it contains oil, the turbine needs to be changed.

• Ball joints of the front axle

The "weakest link" in the suspension. Statistics say that the Audi A4 suspension serves an average of 250 thousand km without repair. Most often, the ball joints of the front axle fail. The main symptom of a malfunction: third-party sounds when the vehicle is moving, especially on poor road surfaces. The maneuverability of the machine is impaired.

Visually assess the condition of the supports. Rubber boots must be intact, securely fixed. The main symptom of a malfunction is a "chomping" sound in the front suspension when driving.

When using low-quality candles or improper car care, the coil quickly fails or works intermittently. The part is expensive. The vehicle will not start well or will not start at all. Poor cravings. The control lamp on the panel is on.
To check, it is necessary to remove the cover from the engine, make a visual inspection of the ignition system. A serviceable coil has no cracks, no rust, all wires are securely fastened. An ohmmeter is needed to fully check the coil.

And this is not surprising. If you buy a car with an engine that has not been repaired or changed on this car, then expect problems. First of all, when buying, you need to check the compression at a car service. Then draw a conclusion and continue to diagnose. Observe the operation of the engine and monitor the rpm. Pay attention to the absence of errors. Sensors are a first-generation disease of the four.

Manual for repair, maintenance and operation of Audi A4 since 1994 release. Hundreds of illustrations show controls and individual stages of work. Quick and easy troubleshooting sections to help you troubleshoot. The wiring diagrams help locate electrical faults and facilitate the installation of additional equipment.

Tell me how to properly adapt the Multitronic box on the Audi A4 B8. The fact is that vibration periodically occurs when accelerating to a certain speed. Some people advise adapting.

Answer:
Hello, Multitronic adaptation is only carried out after repairs (replacement of the input shaft, hydraulics, control unit, etc.). In your case, most likely there is another problem; in any case, you need to perform a comprehensive diagnosis of the suspension and transmission. For a general understanding, here's an instruction on how to adapt the Multitronic box to the Audi A4 B8.

1. We start the engine and warm it up to a temperature of about 80 degrees. At the same time, it is advisable to carry out control through the diagnostic connector of the scanning equipment (VAG COM - block 02 - new type of measurements - channel 38)
2. We move the gear selector lever to position P, without turning off the engine, go to VAG COM in block 02
3. Select 04 -Basic settings and select Resetting of all adaptation values.
4. After a few seconds, a message about the correct completion of the operation should appear.

• remove lighting devices and all electrical wiring from the place to be repaired
• after pulling the spar itself. This is where you need a winch. Fasten the grips exclusively in the areas of horizontal seams (factory welding). Pinpoint the correct direction and pull out the damaged link.
• use the same method to stretch the wing
• trim the floor in the trunk if it is also damaged

When a strong blow has hit the rear of the car, a complete replacement of body panels and power elements may be necessary. When folds appear on the side member, it must be replaced, since it will no longer be able to give the body the nominal stiffness.
