What s tronic were put on the Audi. What is the transmission on the new Audi A4 generation B9. DSG - a robotic version of the Audi A4 gearbox
Increasingly popular among motorists. If abroad the concept of "variator" does not raise questions, then domestic motorists are not used to cars with this type of gearbox. Therefore, now we will tell you what the variator on the Audi A4 is - you can also evaluate the reviews of other motorists in this article.
The main advantage of a variable speed gearbox (hereinafter referred to as CVT) is the ability to efficiently use motor power, compared to other types of gearboxes. Russian and Ukrainian motorists often switch to cars with CVT, fuel economy, lack of jerks when driving and other factors provide a high level of comfort.

What type is on A4 and A6?
As mentioned above, the popularity of CVTs is growing, manufacturers Vehicle more often installed on CVT cars of their own production. So, on cars "Audi A4" "Audi A6" the manufacturer puts variators "Multitronic". This type The gearbox is a continuously variable gearbox.
CVT Multitronic consists of:
- multi-plate "wet" clutch;
- planetary box device;
- intermediate transmission component;
- directly variable speed transmission;
- main speed;
- differential;
- gearbox housing.
This type of CVT is V-belt, and we note that Audi was the first to use a metal chain in their gearboxes. This engineering solution made it possible to increase the range gear ratios. As a result of the operation of the links different sizes, in the CVT, a reduction in the noise of the operation of the gearbox as a whole has been achieved. 
According to the manufacturer, the operation of this type of gearbox allows for maximum dynamism when driving a vehicle, a high level of fuel economy by the engine. What can we say about comfort. The consumer properties of these CVTs are quite high, and they are put on the premium class cars "Audi A4" and "Audi A6". On these modes of transport, the manufacturer installs the CVT model "Miltitronic 01J".
Is this variator subject to repair and where to carry it out?
Not everything can be perfect, as we would like. As they say, "there is always a fly in the ointment in a barrel of honey." We are talking about electronic unit- its location in the CVT unit has one huge drawback. When the CVT is operating, heavy loads are placed on the block. It has to do with heat transmission fluid. Therefore, the electronics unit often fails.
In some cases, even 80 thousand kilometers for a block can be “lethal”. If you contact the manufacturer with such a problem, he will say one thing: "the electronic unit needs to be replaced." You will lose not only a lot of time, since such a device is usually out of stock and ordered from abroad, but also a lot of money. But, if the car is still under warranty, then the dealer can change the electronic unit for free.
This type of failure is the most common, it can be called a disease for Multitronic CVTs. The metal chain breaks less often. But in this case too official dealer will not carry out repairs, but will offer the owner of the car to replace.
You can contact specialized service stations that repair control units. Diagnostics on the computer shows a list of errors when the unit fails:
- 17105 P0721 or 17106 P0722 - the output speed device has failed - in this case, the block signal is incorrect or completely absent;
- 17114 P0730 incorrect block gear ratio;
- 17134 P0750 - the ABS / EDS device has failed;
- 17137 P0753 - no electrical circuit signal;
- 18201 P1793 or 18206 P1798 - the device for the number of output revolutions has failed - in the event of such a breakdown, the signal is incorrect or completely absent;
- 17090 P0706 - the controller position device has failed - the wrong signal is fixed;
- 18226 P1818 or 18221 P1813 - failures in the operation of the electrical circuit were recorded.
The above errors appear like this:
- transport moves jerkily with an increase in speed;
- during gear shifting, the car twitches;
- from time to time, the impossibility of engaging reverse gear appears;
- sometimes, especially for the Audi A6, the car cannot be removed from position P (parking mode).
If you are faced with such problems, then you have only two options - go to the dealer and pay a lot of money for CVT repairs or go to a specialized service station and also pay money, but an order of magnitude less. Self repair at home is not allowed, because for this you need to have at least the necessary knowledge and expensive equipment that is not sold in stores.
The electrical unit itself is located behind the back cover of your CVT. But keep in mind - if this device is being repaired, you will also have to spend money on gear oil. In no case is it allowed to fill in a fake or counterfeit, so you will have to purchase original products. Otherwise, forget about the normal operation of the gearbox. Fluid marked G 052 180 A2 (G052180A2) can be purchased from a dealer or ordered online.
At present, there are many kinds of expensive and quality oils, but only the original is needed. Of course, the fluid can be good, but the lubrication and viscosity characteristics must be as required by the manufacturer. Otherwise mechanical part The CVT will fail earlier and repair will not help here.
For over two years now, Russian market for sale new Audi generation A4, which has become much more interesting than its predecessor, received an upgraded line of engines, transmissions, an all-wheel drive system, as well as a new MLB Evo platform, which underlies crossover Audi Q7. The main competitors of the B9 generation A4 are still the BMW 3 Series and Mercedes-Benz C class, here you can also include the Infiniti Q50, Jaguar XE and Lexus IS. Before each model, Audi has its own advantages, as well as moments in which the car clearly loses to its competitors.
One of the main differences between the new generation and the old one is the company's complete abandonment of the CVT 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 (analogous to VW's DSG DQ500).
Audi A4 B9 with manual transmission
Let's start our acquaintance with a mechanical six-speed transmission, although this kind of car is rarely bought with mechanics, there are still motorists who prefer manual transmission because of its reliability and the ability to fully control the 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, you will have to choose the version with a robot.
- 1.4 liter petrol turbo engine with 150 hp price from 2,020,000 rubles;
- 2.0 liter petrol turbo engine with 190 hp price from 2,170,000 rubles;
Audi A4 B8 S tronic
Many have heard of poor reliability robotic transmissions, however, only the DSG 7 with a dry clutch has been awarded this glory, while the DSG-6 and in particular the S tronic with a wet clutch are considered very reliable transmissions with a long resource.
- 1.4 liter petrol turbo engine with 150 hp price from 2,100,000 rubles;
- 2.0 liter diesel turbo engine with 150 hp price from 2,240,000 rubles;
- 2.0 liter petrol turbo engine with 190 hp price from 2,250,000 rubles;
- 2.0 liter diesel turbo engine with 190 hp price from 2,360,000 rubles;
- 2.0 liter diesel turbo engine with 190 hp four-wheel drive price from 2,444,000 rubles;
- 2.0 liter petrol turbo engine with 249 hp price from 2,500,000 rubles;
- 2.0 liter petrol turbo engine with 249 hp all-wheel drive price from 2,584,000 rubles;
On the forums, you can often find the question of which box is better to buy an A4 with S tronic or with mechanics, which of them is more reliable. There is no single answer to this question, because. everyone must decide for himself what suits him more robot or still mechanics. But regarding reliability, mechanics 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, S tronic can easily pass 100,000 - 150,000 km without maintenance, then it is better to replace the mechatronics and clutch. We also recommend that you remember to timely replacement oil, and it is better to do this at 50,000 km if the car is often operated in traffic jams in gas / brake mode.
Unlike the Audi A6, in the fourth modification, the main focus was on a continuously variable variator and an automatic transmission type. Classical mechanics is used less frequently.
In general, the reviews of the owners of the Audi A4 are positive. There are no special complaints about the build quality, the duration of operation. The most frequent visits to service stations are associated with planned preventive maintenance, replacement transmission oil.

Typical Audi A4 gearbox problems, at what mileage do they occur
| Mechanism | signs |
|---|---|
| The brake band develops a resource after 180 thousand km of run | Clamps wear out, the surface of the drum. Signs: slip, 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, slipping clutch |
| Incorrect operation of the electronic control unit of the computer | Power surges, loose terminal contact, resulting in a “Check Engine” error on the tidy. |
| Deterioration of the torque converter block | The reason is an aggressive driving style, "sporty" starts at traffic lights. Vibration appears in the gearbox, knocks, shocks when shifting to higher gears |
| Cold transmission | Driving in a cold transmission will result in premature wear hydroblock |
Self-diagnosis without special equipment is not always effective. Sometimes, the defect is 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 or a variator.
| Mechanism | signs |
|---|---|
| Transmission does not engage when pushing backstage | The reason is insufficient oil level. When the lubricant does not completely wash the drive shaft. Rarely stretched cable drive during its long-term operation without intermediate prophylaxis |
| There is a smell of burning near the car | Insufficient amount of oil, increased operating temperature, as a result of which the rubbing surfaces stick. A number of European automakers install radiators - coolers similar to the automatic type to prevent overheating. However, this does not always help. |
| When driving in neutral gear, noise, rumble, vibrations are heard | The transmission needs to be dismantled, disassembled, and troubleshooted. Based on the results of the diagnostics, the master decides on the advisability of further use of the unit. Roller bearing wear - common cause appearance of noise |
| Working out on clamps - the reason for knocking out speeds | Less often they state wear of the drive gear, drive shaft |
| Jamming clutch | 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 its constituent elements. Rope stretch is also one of the causes of jamming |
| Metallic grinding, vibration | The reason is an unadjusted clutch, excessive wear of clutches, synchronizers |
| Constant noise while driving | Roller bearing failure is the most likely cause of outside noise |
| Depressurization | Leakage of transmission oil leads to a decrease in lubrication level, increase operating temperature, jamming of the working surface, rubbing parts |
| "Check Engine" | On the dashboard the "Check Engine" indicator signals. |
To check the oil level, unscrew filler plug on the gearbox housing. The level is sufficient if the grease begins to flow out. Otherwise, replenish the missing amount.
Do not ignore the dashboard signals. Malfunctions require the prompt intervention of the service station master. Use a portable diagnostic scanner to decrypt.
Audi A4 cars are equipped with digital sensors that monitor online technical condition aggregates. Current information is displayed on the dashboard display. As soon as the lamp lights up, be sure to turn off the engine, check the oil level, signs of depressurization, mechanical damage.
DSG - a robotic version of the Audi A4 gearbox
| Mechanism | signs |
|---|---|
| Wear of friction linings, clutches | Disappears periodically reverse gear, when even speeds are activated, jerks appear. Frequent transitions to emergency mode, control unit error |
| Solenoid wear | Jerks during the transition to an increased range of speeds |
| Unstable and incorrect work mechatronics, electronic control unit | At the time of a cold start, the gearbox briefly switches to emergency operation, after a few seconds we restore full operation again |
| Key flashing instead of gear indicator on dashboard | The operation of the machine is prohibited until the source of the failure is identified. |
| Wear of bearings, input shaft splines, differential | While driving, a noise is heard in the area of \u200b\u200bthe gearbox installation |
| Flywheel premature wear | Riding is accompanied by clanging and noises |
Repair or replacement of gearbox
We provide comprehensive diagnostics 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 a modular replacement, it is not advisable to restore the box in stages.
What kind of oil to fill in the Audi A4 model: synthetic-based, viscosity grade 75W - 85 (90, 95), API SL / CF classification.
Audi A4 gearbox diagnostics
| Mechanism | signs |
|---|---|
| Checking the transmission oil level | We unscrew the control plug, if the liquid flows out, then the level is sufficient. Otherwise, replenish the missing amount |
| Oil Quality Check | There should be no burning smell, cloudy sediment, dark color. The natural color scheme is light brown with a 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, filters, general inspection of the body for cracks. The presence of large metal chips is the first sign of failure of the torque converter. Copper shavings - wear of shafts, pump. Magnetic chips - clutches |
| Checking the oil pressure with a special measuring device | We connect the equipment to the threaded hole on the filler neck of the gearbox. We start the engine, it works on Idling, gradually move the selector (lever) to the position of the first and subsequent gears. At this point, the device records the minimum and maximum pressure. Based on the results, compares the results with the standards in the instruction manual |
| slip test | Press the brake pedal, then press the accelerator pedal. In good clutch condition, the motor chokes from the load, but does not develop speed. Otherwise - slipping, engine roar |

The Audi A4 has gained great popularity among car enthusiasts because this car is equally well suited for both family car enthusiasts and a single driver, for example, for daily commuting. One way or another, the car is prestigious, well-equipped, but, alas, not cheap either in the initial purchase or in further operation. But how often investments will be required after buying 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 maintain the connection of A4 with the eighties, the management of the company "" decided to keep the generation calculation that began back in 1960. So the production of the Audi 80 was discontinued on the fourth generation, and the first generation of the model received the classification "B5". The car that will be discussed today is listed as "B7" (third generation), and was produced from 2004 to 2007, is a deeply modernized predecessor. The design of the car and suspension have undergone changes, and four new engines have also appeared. The front part of the body of the Audi A4 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 Audi A4 with mileage
This model is equipped with petrol 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 type and a hydraulic valve lifter that do not require adjustment. two liter naturally aspirated engine reliable enough, and up to 150,000 km does not require special attention, and after the specified run, the motor begins to gradually eat up oil (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. Provided correct operation the turbine will live 200 - 250 thousand km.
But two-liter engine can present unpleasant surprises, so, in particular, after 100,000 km of run, carbon deposits and wear are formed on the injection pump pusher and camshaft. Closer to 150,000 km, through valve cover starts to drive oil (to fix this problem, you will have to pay about 250 USD). Usually, the cause of this phenomenon is a faulty crankcase ventilation valve, and in such cases, oil can press not only from under the gasket, but also enter the candle wells. After 100,000, the ignition coils fail one by one (the cost of one is about 50 USD). With a mileage of over 150,000 km, 99% of cars consume oil, and, unlike an atmospheric engine, the consumption here reaches one liter per 1000 km. Sometimes decarbonizing the rings helps to eliminate this drawback. The turbine, like the 1.8 engine, serves 200 - 250 thousand km, but with a run of more than 150,000, it starts to take more oil.
A two-liter turbodiesel will most likely please you with its reliability and lack of investment in 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 kilometers, the nozzles will need to be replaced, and it is worth noting that their cost is quite high. thermostat, custom modern cars, serves for a long time and requires replacement every 120 - 150 thousand km. At the same mileage, a cooling system pump will be asked for 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, the Multitronic CVT (Multitronic) and the six-speed Tiptronic automatic - 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 changes. The clutch, during normal operation, goes up to 150,000 km, closer to 200,000, you will have to replace the synchronizers. Multitronic, up to 150,000 is not satisfactory, and after that it may start to enter emergency mode, but do not be very scared, since this is most likely due to failures in the electronic control unit.
Installed on the Audi A4 automatic transmission gear from 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 USD), at the service you may be offered to repair the old one, but you should not do this, since the repaired part does not last long. The recommendation for extending the life of transmissions is simple - change a few times every 40 - 60 thousand km.
Vulnerabilities of the Audi A4 chassis
Front suspension Audi A4 (B7), four-link, rear - on trapezoidal levers. Many people think that the Audi suspension is not quite for our roads, but this is not true. During normal operation, the suspension will have to be repaired once every 100,000 km, but, in fairness, it’s worth saying that you need to invest a lot in this unit. For example, replacing rattling levers in a circle will cost 800 - 900 USD, four shock absorbers (non-original) 300 - 400 USD. On the brake system owners usually don’t have any complaints, the pads are here good quality and are capable of serving up to 60,000 km. Closer to 200,000 km, a steering rack repair will be required, which will cost 200 - 250 USD.
The all-wheel drive transmission in the quattro version is quite reliable, and all you need to do in it is to make sure that the seals do not start to leak, and if a leak forms, it must be quickly eliminated. With a run of 150,000 km or more, on many machines there is a backlash in the cardan bearing bearing, 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 cabin of the Audi A4, air flow control, as well as the recirculation system, begin to act up; in such a situation, usually the reason is the wear of the servos. If your air conditioner has stopped working, then first check the presence of refrigerant and the tightness of the system, then the operability of the air conditioning 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 freezing (try to drive into 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 than that, be sure to change the engine oil, and the timing belt every 50,000 km. These cars love fuel High Quality, and we, unfortunately, can not always offer them this. Due to the fact that with the onset of cold weather, many sensors begin to fail, owners often call the A4 “sissies”.
Advantages:
- Design
- Build quality.
- The quality of body metal and paintwork.
- Balanced suspension.
- Interior finishing materials.
- Audio system sound.
Flaws:
- High maintenance cost.
- Fuel consumption gasoline engines(12 liters per hundred)
- Increased oil consumption after 100,000 km.
- Electronics is afraid of frost
- Small ground clearance.
If you are the owner of this car model, please describe the problems that you had to face during the operation of the car. Perhaps it is your review that will help readers of our site when choosing a car.
