Unlike the Audi A6, in the fourth modification, the main bias was made for a continuously variable variator and an automatic transmission type. Classic mechanics are used less frequently.
In general, the owners' reviews about the Audi A4 are positive. There are no particular complaints about the build quality and the operating time. The most frequent calls to the service station are associated with planned prevention, replacement transmission oil.

Typical problems of the Audi A4 gearbox, at what mileage occur
| Mechanism | Signs |
|---|---|
| The brake band develops a resource after 180 thousand km of run | Retainers wear out, drum surface. Signs: slipping, unstable work, power reduction, periodic transition of the box to emergency mode |
| Friction disc wear | Signs: "knocking out" gears in motion, bumps when shifting to low speeds, clutch slippage |
| Incorrect operation of the electronic control unit ECU | Voltage surges, weakened contact of the terminals, as a result of which there is a "Check Engine" error on the tidy. |
| Torque converter block wear | The reason for the aggressive driving style, "sporty" starts at traffic lights. Vibration appears in the checkpoint, knocks, jolts when shifting to higher gears |
| Cold transmission | Driving on a cold transmission leads to premature valve body wear |
Self-diagnosis without special equipment is not always effective. Sometimes, the defect is located inside the box body, contact the service station specialists for help. The nature of mechanics malfunctions is not as destructive and costly as that of an automatic machine, a variator.
| Mechanism | Signs |
|---|---|
| The transmission does not turn on when you press the wings | The reason is insufficient oil level. When the grease does not wash the drive shaft completely. Stretching of the cable drive is less common during its long-term operation without intermediate prophylaxis. |
| A burning smell is heard near the car | Insufficient amount of oil, increased operating temperature, as a result of which rubbing surfaces stick together. A number of European car manufacturers use radiators - coolers similar to the automatic type to prevent overheating. However, this does not always help. |
| When driving in neutral gear, noise, hum, vibrations are heard | The transmission needs dismantling, disassembly, troubleshooting. Based on the diagnostic results, the master decides on the advisability of further use of the unit. Roller bearing wear is a common cause of noise |
| Working out on the clamps is the reason for knocking out speeds | Less often, wear of the drive gear, drive shaft |
| Clutch jammed | The clutch disc does not disengage from the flywheel when the brake pedal is depressed. To give a final conclusion, it is necessary to carry out diagnostics, disassemble into constituent elements... Stretching the cable is also one of the reasons for jamming. |
| Metal grinding, vibration | The reason is not adjusted clutch, excessive wear of clutches, synchronizers |
| Constant hum when driving | Roller bearing failure is the most likely cause of side noise |
| Depressurization | Leakage of transmission oil leads to a decrease in the lubricant level, an increase in the operating temperature, seizure of the working surface, rubbing parts |
| Check Engine | On dashboard is signaled by the "Check Engine" indicator. |
To check the oil level, unscrew filler plug on the checkpoint housing. The level is sufficient if the grease starts to run out. Otherwise, fill up the missing amount.
You do not need to ignore the dashboard signals. Malfunctions require prompt intervention of the workshop master. Use a portable diagnostic scanner for decryption.
Audi A4 vehicles are equipped with digital sensors that monitor online technical condition aggregates. Current information is displayed on the dashboard display. As soon as the lamp comes on, be sure to turn off the engine, check the oil level, traces of depressurization, mechanical damage.
DSG - robotic version of the Audi A4 gearbox
| Mechanism | Signs |
|---|---|
| Wear of friction pads, clutches | Disappears periodically reverse gear, when even speeds are activated, jerks appear. Frequent transitions to emergency mode, control unit error |
| Solenoid wear | Jerks when switching to an increased range of speeds |
| Unstable and incorrect operation of mechatronics, electronic control unit | At the moment of cold start, the gearbox briefly switches to emergency operation mode, after a few seconds we restore full-fledged operation again |
| The key flashes instead of the gear indicator on the dashboard | Do not operate the machine until the source of the damage is identified. |
| Wear of bearings, splines input shaft, differential | When driving a car, noise is heard in the area of \ u200b \ u200bthe checkpoint installation |
| Premature flywheel wear | Riding is accompanied by clanking and noises |
Repair or replacement of gearboxes
We carry out comprehensive diagnostics in a technical center using digital equipment. We analyze the data obtained, evaluate the general condition of the unit, the nature of system errors, and the presence of defects. The master draws conclusions about the suitability of the checkpoint for further use.
In case of mechanical damage to the case, defects, depressurization, we carry out the replacement modularly, it is inexpedient to restore the box in stages.
What kind of oil to fill in the Audi A4 model: on a synthetic basis, viscosity class 75W - 85 (90, 95), classification according to API SL / CF.
Diagnostics of the Audi A4 gearbox
| Mechanism | Signs |
|---|---|
| Checking the transmission oil level | We unscrew the check plug, if the liquid flows out, then the level is sufficient. Otherwise, fill up the missing amount |
| Oil quality check | There should be no burning smell, cloudy sediment, dark color. Natural color range is light brown with slight darkening. The shade depends on the amount of chemical components added to the composition. Oil change as needed |
| Pallet integrity check | Dismantling, cleaning of separating magnets, filter, general inspection of the case for cracks. The presence of large metal shavings is the first sign of failure of the torque converter. Copper shavings - wear of shafts, pump. Magnetic shavings - clutches |
| Checking the oil pressure with a special measuring device | We connect the equipment to the threaded hole on the gearbox filler neck. We start the engine, idle, step by step move the selector (lever) to the position of the first and subsequent gears. At this moment, the device records the minimum and maximum pressure. As a result, compares the results with the standards in the instruction manual |
| Slip test | Press the brake pedal and then press the accelerator pedal. In good condition of the clutch, the motor chokes from the load, but does not develop speed. Otherwise - slipping, engine roar |

1. DSG with "dry" clutches, as a rule, are installed on less powerful engines, because are able to "digest" a smaller moment.
2. If you have four-wheel drive then you have a "wet" clutch.
3. If you have a DSG and a motor "along", then you have an Audi :-)
4. Apparently, the century of the legendary full drive Audi Quattro with the famous Torsen differential coming to an end.
Question 002:
Q: How do I know which box is installed on my car?
A: Option 1: Connect the diagnostic device to the vehicle, enter block 02 - Gearbox electronics and read the identification data. The first three characters of the box ID and mechatronics designate your box.
For example: 0AM 300049H is a seven-speed DSG with dry clutches of the 0AM type. Or 02E 300051R - six-speed DSG with wet clutches type 02E, etc.
Option 2: Look by the VIN-code of the car in the electronic spare parts catalog ETKA.
Option 3: Send the VIN-code of the car to our address, we will check and send you an answer.
Question 003:
Q: How is the S-tronic for Audi different from the DSG for VW / Skoda / Seat?
A:Nothing. Except for boxes 0B5, 0CK / 0CL and 0CJ which are installed only on audi.
Question 004:
Q:What kind of oil is used in DSG?
A:For convenience, we have formulated the answer in the form of a table:

Q:What is mechatronics?
A:Mechatronic (mechatronic, mechatron, valve body, brain) - electronic-hydraulic gearbox control unit. Perhaps the most important, but at the same time, the most unreliable component in the entire transmission.
Question 006:
Q:What is the difference between mechatronics?
A:Each type of DSG has its own type of mechatronics. Mechatronics from different DSG types are not interchangeable. Moreover, for some types of DSG, there are several generations of mechatronics that also differ from each other. And for each type and generation of mechatronics, there are many versions of the software, designed for different engines and different gear ratios in the gearbox. In some cases, mechatronics of the same type can be reprogrammed (reflash) to be installed on different cars... You can read more about the firmware.
Question 007:
Q:Which DSG is better / more reliable?
A:There is no definite answer to this question. Each type of DSG has its own advantages and disadvantages. And the duration of the "life" of any DSG largely depends on the conditions of its operation, such as:
- Ambient temperature. All DSGs do not like overheating, especially DSGs with "dry" clutches, in which the mechatronics has a separate oil circuit and there is no cooling;
- Driving mode. Those who spend several hours every day in traffic jams have more chances to come to replace mechatronics than those who mainly travel long distances along the highway;
- Driving style. Those who like to "give a corner" and "light up at a traffic light" have a much higher probability of getting a replacement clutch and differential than those who prefer a quiet ride.
Question 008:
Q: I have DSG7 0AM.Do I need to switch the selector to neutral when standing at a traffic light or in a traffic jam?
A: No need.Unlike conventional manual gearboxes, the clutch on the DSG7 0AM is normally open. And it closes only when the mechatronic begins to extend the clutch release rods. When you (or autohold) hold the car in place by pressing the brake, the mechatronics clutch rods are retracted and the clutches are open. Accordingly, no load is transferred to the gearbox or clutch. In what position the selector knob is in this case - it does not matter.
Question 009:
Q: Over time, there were jerks when changing gears. Previously, the car drove fine, shifting was smooth, but recentlyjerks and shocks appeared when shifting gears. Can this be fixed by reprogramming the box ECU (software update)?
A: No, you can't. The software cannot "deteriorate" over time and cause the CP to malfunction. If the car previously drove correctly, and then stopped, then the problem lies in the hardware, and not in the software.
Reprogramming the mechatronics can only help if the mechatronics was changed and the unit was installed with the wrong software. You can read more about reprogramming.
Question 010:
Q:How to find out the software version in mechatronics?
Question 011:
Q: DSG7 shift knob is locked in position P, how to unlock it in order to shiftbox to neutral?
A: Brief instructions for unlocking the DSG7 0AM selector.
Question 012:
Q: Will changing the oil in mechatronics DSG7 0AM (0CW) help to remove the "kicks" on gear changes?
A: No, it won't help. Such malfunctions are eliminated by repairing the hydraulic part of the mechatronics. In the initial stages, adaptation (basic setting) can help, but rather as an exception than a rule.
Question 014:
Q: After replacing the DSG7 0AM mechatronics, the errors "06247 P1867 - Drive data bus no messages from the steering column electronics - J527" and "06227 P1853 Drive data bus implausible message from the ABS control unit" are displayed in the event logger. How do I remove them?
A:It is necessary to reset the information about the installed components (steering column switches, electric parking brake, etc.). To do this, you need to make a basic installation on channel 69. After performing the basic installation, errors will change from the "permanent" state to the "sporadically" state and you can delete them.
When using VCDS software (VAG-COM, Vasya-Diagnostic, etc.):
"02-Gearbox electronics" -> "Basic parameters - 04" -> In the "Group" field enter the value 69 -> Press "Read".
When using softwareVAS-PC:
"Self-diagnosis" ->"02-Gearbox electronics" -> "006-Basic setting"-> In the "Group" field enter the value 69 -> Press "Q".
When using softwareODIS:
"Self-diagnosis" ->"02-Electronics KP" ->"Basic Installation" ->Enter value 69 -> Press "Channel selection".
After the basic installation, the event recorder must be cleaned.
Question 015:
Q:Structurally, DSG7 0AM and DSG7 0CW are practically the same transmissions (DQ200 family), is there any difference between the mechatronics installed on them?
A:The main difference is the physical and software changes to the electronic control board. In particular, 0CW boards are tied to the vehicle immobilizer system. You can read more about the differences in mechatronics 0AM and 0CW.
Many drivers know how to drive an Audi A4 automatic transmission. But for some, our article will serve as a small introductory lesson on the topic of studying automatic transmissions of this well-known automaker.
A bit of history of the Audi brand.
Father and mastermind car brand Audi is Ferdinand Piech, who took over in 1974 as head of the company's advanced development department. Being not only a talented designer, but also a competent, perspicacious marketer, Pich was able to convince the company's management of the need to radically change the company's position in the market.
He began developing a four-wheel drive passenger car, experimenting with aluminum, and in 1980. Audi company surprised car enthusiasts all over the world by presenting an all-wheel drive sports coupe at the Geneva Motor Show Audi quattro ... This model was truly revolutionary, since before that all-wheel drive was the privilege of trucks and SUVs. For Pih, it was a kind of experiment that fully met his expectations. Continuing to develop the all-wheel drive concept in passenger cars, it releases in 1984. Audi models 90, which was developed only for US sales, and its European counterpart, the Audi 80.
Audi Quattro 1980
The Audi 100, which was released in 1990, became the most expensive model of the automaker. This is the first car to be used by Audi in the premium class. Wealthy customers could purchase a model with a new six-cylinder V-type engine, which was the lightest and most compact among its counterparts of similar power.
Audi 100 Thanks to the new fuel injection system and other innovative solutions, Audi engineers managed to remove 174 full-fledged horsepower... At the same time, the new engine retained great power even at high revs.
New representative in the lineup
Continuing to conquer the elite segment of the car market, the automaker produces in 1994 Audi sedan A8. The heavy and powerful executive car was popular due to the increased stability (and therefore safety), which was provided by the same four-wheel drive.
In 1996, the company presented the world with a compact Golf class car - the Audi A3.
Audi A8 The development costs of the model turned out to be minimal, since the production of this car was based on the already finished VW Golf platform. However, thanks to the sporty style and high quality of the interior, the class of the car was one step higher, which brought it closer to competitors from Mercedes and BMW.
For a long time, Audi did not offer anything worthy of SUV enthusiasts, while the company's competitors offered their customers several models of cars of this class. The Q7 SUV, which appeared in 2005, made up for this delay, instantly gaining popularity among fans of giant cars.
Model A4.
The successor of the Audi 80, which was produced from 1986 to 1994, is the A4 model, which entered the series since November 1994. The car has acquired a more impetuous outline of the body, and the magnificent interior of the cabin conquers with its comfort. Along with this, the new model has implemented a number of improvements related to passive safety: the car is better able to withstand a blow to the side pillars, to basic configuration added two side airbags (in addition to the two front ones)
1994 Audi A4 Car enthusiasts can order this model in one of several variations:
- 1.6 or 1.8-liter petrol engine with 4 cylinders (101 and 125 hp respectively),
- 2.6 and 2.8 liter V-shaped six-cylinder engine (174 hp),
- and a 1.9-liter turbodiesel (110 hp).
The car body is made of galvanized steel, so it is completely protected from corrosion. The proof of reliability and quality is the 10-year body warranty provided by the manufacturer.
Models with gasoline engine equipped with Tiptronic, which made it possible to change gears in manual mode. This option allows an experienced driver to show their skills.
Automatic transmission for Audi A4.
There are now two models of automatic transmission used in the Audi A4:
- "AG-4" for a naturally aspirated four-cylinder engine developed by VW;
- "5 HP 18" for a six-cylinder engine (developed by ZF).
New Audi A4 with automatic transmission Both models are controlled electronically and hydraulically. The inclusion of gears depends on the following parameters:
- engine speed;
In addition to the input parameters, the control takes into account:
- the driver's driving style (recognizing it, the automatic machine independently sets the gear shift points);
- terrain (the shift mode on a mountain road will differ from the mode on a flat road).
How to operate this automatic box.
- Driving off the car. As soon as you start the engine, put the car on the brake, and only then move the selector lever from position P or N to the desired range of motion. Otherwise, your car will start moving at a low speed.
- Do not under any circumstances press the brake and accelerator pedals at the same time. Under normal conditions, the automatic transmission should be in the "D4" position constantly.
- Operate the accelerator pedal smoothly without jerking. In this case, switching of the automatic transmission to higher gears will occur quickly, thereby ensuring low fuel consumption. Use the ranges "2" "1" only in those cases when you need to perform quick engine braking or exclude unnecessary switching of the machine to higher gears.
- Kick-down mode. At low speeds, you can go down to a lower gear by pressing the accelerator pedal all the way down. This will allow you to use the full power of the engine to accelerate the vehicle.
- Stopping the car. When the car stops, the selector lever can remain in one of the driving ranges. The engine will idle.
Gearbox selector lever Audi A4 - At the moment of stopping on a slope, if one of the driving ranges is switched on on the automatic transmission, and the car is held by the brake, do not increase the crankshaft speed. Turn off the engine when stopping for a long time.
- Maneuvering. When maneuvering in small areas (garages, parking lots, etc.), use the mode with the accelerator pedal fully depressed. Adjust the speed by lightly pressing the brake pedal. Never press the brake and accelerator pedals at the same time.
Automatic transmission diagnostics.
There are many diagnostic methods for an automatic transmission. Consider the main ones that allow you to assess the condition of the automatic transmission.
- Oil condition and level.
- The level is checked with a dipstick with risks marked on it. The oil should be pure red with no burning smell. If the oil is drained into a separate container, then whitish streaks should not remain when it is stirred.
Engine compartment of the Audi A4 with V6 engine Ready time. Warm up the car to normal rpm idle move... Standing on the brake, switch N-> D and N-> Dh and note the time before the jolt (the moment the machine is turned on). It should not exceed 1 second. Now switch N -> R and time again. You should have less than 1.2 seconds. If the time intervals are higher than indicated, then this means wear of the clutches.
Diagnostics on the road
- Select a straight section of road.
- Check the position of the accelerator and its indication on the instrument panel.
- With the selector shifted to D, accelerate and decelerate alternately at half and full throttle. Make sure to switch 1—> 2, 2—> 3, 3—> 4 and 4—> 3, 3—> 2, 2—> 1.
- While driving in fourth gear, shift the selector to position 5 and make sure that the shift from 4 to 3 occurs immediately.
- Enter Dh mode. See if there is any inclusion 1 and 4, and how the switching is going on 2-> 3 and 3-> 2.
- While the car is moving in gears 2, 3, 4, listen, perhaps the automatic transmission is humming.
Diagnostics by codes... There is a diagnostic connector located under the hood of your vehicle. Connect a jumper between the TAT and GND contacts and turn on the ignition. The HOLD light should light up once for a few seconds and then go out. If after that it continues to flash with impulses (short or long), the automatic transmission of your car needs to be repaired.
Planned Maintenance Audi A4 Diagnostics of the mechanical part of the automatic transmission. It is carried out without disassembly by checking the pressure (linear) in all modes. But this procedure cannot be carried out without special equipment.
Repair of the automatic box Audi A4
Automatic transmission repair always begins with diagnostics (often computer). Sometimes it happens that, as a result of diagnostics, a cause is revealed that is not related to mechanics, but to the electrician of the machine. How much it costs to repair an automatic gearbox can only be said after the volume and complexity of the work has been determined.
The most common reason for the failure of the machine is banal negligence in relation to timely maintenance. For example, if the oil and oil filter were not changed in time, and the box was allowed to overheat (slipped, towed a trailer, your car has a clogged radiator, etc.), then the following will happen:
- There is a shortage of oil on the slip sleeve of the torque converter;
- The bushing turns, the rest of the oil flows out of the box;
- Clutches burn out without oil.
For example, the cost of repairs in this case (oil and filter replacement) will be about 3,000 rubles.
For more than two years now Russian market a new generation of Audi A4 is being sold, which has become much more interesting than its predecessor, has received an upgraded line of engines, transmissions, an all-wheel drive system, and new platform MLB Evo, which is at the heart of the Audi Q7 crossover. The main competitors of the A4 generation B9 are still the BMW 3 Series and Mercedes-Benz C-class, this also includes the Infiniti Q50, Jaguar XE and Lexus IS. Before each of the models, Audi has both its own advantages and moments in which the car clearly loses to its competitors.
One of the main differences between the new generation and the old is the company's complete abandonment of the variator in favor of a robot with two clutches, which was recognized as much more reliable and practical. Now potential owners can choose between a 6-speed manual and a 7-speed S tronic robot (analogue of VW's DSG DQ500).
Audi A4 B9 with manual transmission
Let's start our acquaintance with a mechanical six-speed transmission, although cars of this kind are rarely bought with mechanics, there are still motorists who prefer manual transmissions because of its reliability and the ability to fully drive a car.
Unfortunately, in the new generation with mechanics, you can only choose front-wheel drive, so forget about the legendary combination of all-wheel drive and mechanics, you need a quattro to have to choose a version with a robot.

On the forums, you can often come across the question of which box is better to buy A4 with S tronic or mechanics, which of them is more reliable. There is no unambiguous answer to this question, tk. everyone must decide for himself that a robot is more suitable for him or still a mechanic. But regarding reliability, the mechanic will definitely be more reliable and cheaper to maintain, but this does not mean that a robot with two wet clutches is not reliable, just mechanics are mechanics. As practice shows, the S tronic can easily pass 100,000 - 150,000 km without maintenance, then it is better to replace the mechatronics and the clutch. We also recommend not to forget about a timely oil change, and it is better to do this at 50,000 km, if the car is often operated in traffic jams in the gas / brake mode.

The Audi A4 has gained great popularity among car enthusiasts because this car is equally well suited for both family car enthusiasts and a lone driver, for example, for daily trips to the robot. One way or another - the car is prestigious, well-equipped, but, alas, not cheap, neither in the initial purchase, nor in further operation. But how often investments will be required after purchasing this model on secondary market, now let's try to figure it out.
A bit of history:
This model replaced the morally and technologically obsolete Audi 80 in 1994. In order to keep the A4's connection with the 80s, the management of the company decided to keep the calculation of generations that began in the distant 1960. So the production of the Audi 80 was discontinued in the fourth generation, and the first generation of the model received the classification "B5". The car, which will be discussed today, is listed as "B7" (third generation), and was produced from 2004 to 2007, is a deeply modernized predecessor. Changes have been made to the car's design and suspension, as well as four new engines. The front part of the Audi A4 body has completely changed, a single radiator grille in the form of a trapezoid has appeared, the headlights have become slightly curved towards the bottom. The changes also affected the trunk lid, rear lights, rear bumper and chassis; the interior of the car began to be sheathed with expensive fabric, velor or leather.
Weaknesses of the used Audi A4
This model is equipped with gasoline and diesel engines... Most often, in the secondary market, there are cars with gasoline with a two-liter aspirated, or with turbocharged engines of 1.8 and 2.0 liters. All engines are equipped with a timing belt and hydraulic valve lifters that do not require adjustment. Two-liter atmospheric engine quite reliable, and up to 150,000 km does not require special attention to itself, and after the specified mileage, the engine begins to eat up oil a little (up to 300 grams per 1000 km). Of the turbocharged engines, the most reliable unit with a volume of 1.8 liters, but very demanding on quality lubricants... On condition correct operation the turbine will live 200-250 thousand km.
And here two-liter motor can bring unpleasant surprises, so, in particular, after 100,000 km of run, carbon deposits and depletion form on the pusher of the injection pump and the camshaft. Closer to 150,000 km, oil begins to drive through the valve cover (to eliminate this problem, you will have to pay about 250 USD). Usually, the cause of this phenomenon is a faulty crankcase ventilation valve, and the oil in such cases can press not only from under the gasket, but also fall into the candle wells. After 100,000, the ignition coils alternately fail (the cost of one is about $ 50). With a mileage of over 150,000 km, the engine eats oil on 99% of cars, and, unlike an atmospheric engine, the consumption here reaches one liter per 1000 km. Sometimes de-carbonization of the rings helps to eliminate this deficiency. The turbine, like that of the 1.8 engine, serves 200-250 thousand km, but with a mileage of more than 150,000, it begins to take more oil.
A two-liter turbodiesel will most likely delight you with its reliability and lack of investments for repairs up to 200,000 km, provided that the previous owner serviced the car on time and refueled with high-quality fuel. After 200 thousand km of run, the injectors will need to be replaced, and it is worth noting that their cost is quite high. Thermostat, by the standards modern cars, lasts long enough and requires replacement every 120 - 150 thousand km. With the same mileage, a pump of the cooling system will be asked for a replacement, but fuel pump lives longer - about 200,000 km.
Transmission
On the Audi A4 (B7), you can find five- and six-speed manual gearboxes, a "Multitronic" variator and a six-speed automatic "Tiptronic" - only on all-wheel drive versions. Mechanical transmission, in general, not killed, but some owners of cars with a mileage of more than 100,000 km, complain about fuzzy gear shifting. The clutch, during normal operation, goes up to 150,000 km, closer to 200,000, the synchronizers will have to be replaced. Multitronic, up to 150,000 does not cause any complaints, and after that it may start to enter emergency mode, but you should not be very scared, since this is most likely due to failures in the electronic control unit.
The Audi A4 is equipped with automatic transmission gears from the well-known manufacturer "ZF". If, during acceleration, you feel small jolts, then most likely the problem is in the torque converters. Buying a new torque converter is not a cheap pleasure (about $ 800), at the service you may be offered to repair the old one, but this is not worth doing, since the repaired part does not last long. The recommendation for extending the life of transmissions is simple - change it a few times every 40-60 thousand km.
Vulnerabilities of the chassis of the Audi A4
Front suspension Audi A4 (B7), four-link, rear - on trapezoidal levers. Many people think that the Audi suspension is not really for our roads, but this is not true. Under normal operation, the suspension will have to be repaired once, every 100,000 km, but, in fairness, it's worth saying that a lot needs to be invested in this unit. For example, replacing knocked levers in a circle will cost 800 - 900 cu, four shock absorbers (non-original) 300 - 400 cu. On brake system the owners usually do not have any complaints, the pads are here good quality and are capable of serving up to 60,000 km. Closer to 200,000 km, the steering rack will need to be repaired, which will cost 200 - 250 USD.
The all-wheel drive transmission of the quattro version is quite reliable, and all you need to do in it is to make sure that the oil seals do not start leaking, and if a leak occurs, it must be quickly repaired. With a mileage of 150,000 km or more, on many cars a play appears in the bearing of the cardan support, and in order not to have more serious problems, it must be eliminated in time by replacing the bearing.
Electrical equipment
Over time, in the interior of the Audi A4, the air flow control, as well as the recirculation system, begin to flounder; in such a situation, usually the reason is the wear of the servos. If your air conditioner stops working, then first check the presence of refrigerant and the tightness of the system, then - the operability of the air conditioner control sensor. If the airbag indicator does not go out during the cold season, then the cause of this failure may be the airbag sensor hanging (try to enter a heated parking lot, and most likely the problem will be solved by itself).
Outcome:
When buying a used Audi A4, you should understand that the guarantee of your long and joint life with this car, first of all, depends on regular visits to a car service. Once every 15,000 and no less often, be sure to change the oil in the engine, and the timing belt - every 50,000 km. These cars love fuel High Quality, and we, unfortunately, are not always able to offer them this. Due to the fact that with the onset of cold weather, many sensors begin to malfunction, owners often call A4 “sissies”.
