The design of mechanical and automatic transmissions is constantly being improved. Each of these constructive types transmission has both advantages and disadvantages. The main disadvantage of a classic automatic transmission is the release of power when shifting gears. That is why many automakers have developed and are developing modernized automatic transmissions that allow you to change gear without breaking power.

Audi S-Tronic gearbox

The design idea of ​​such a preselective transmission is extremely simple. The operating principle was taken mechanical box gears with two shafts. In fact, such a gearbox has two clutches that allow you to switch gears without breaking power. This allows not only to improve dynamic performance, fuel consumption is significantly reduced and improves the safety of the car when performing high-speed maneuvers and overtaking. Currently on Audi cars a seven-speed s-tronic robotic preselective gearbox is standard. This transmission has established itself as a fairly reliable and high-tech gearbox, which provides maximum comfort driving.

One of the benefits of using these preselective seven-speed s-tronic automatic transmissions is compact dimensions transmission. This makes it easy to use preselective gearboxes on compact cars that have limited engine compartment space. AT this case it is difficult to install a full-fledged six-seven-speed gearbox in such a limited engine compartment. The use of the s-tronic preselective machine in this case has become optimal solution small car problems. Now small city cars from Audi have received the possibility of using multi-speed automatic transmissions that optimally implement dynamic potential power unit and save fuel.

The design of the S-Tronik box

How does S-Tronic work?

By its design, such a preselective s-tronic gearbox is closer to mechanical transmissions that are equipped special device for fully automatic step changeover. There are special paddle shifters for manual gear changes. In this case, switching takes place in a fraction of a second, and power is not interrupted due to the presence of two clutches. It is possible to activate completely automatic operation operating mode, when the electronics independently decides on a gear change. Audi's seven-speed s-tronic gearbox has a fully computerized control that monitors the parameters of the transmission. If there are any malfunctions in the operation of the automatic transmission, a corresponding warning is displayed. This not only increases the ease of use of the transmission, but also simplifies the subsequent one. With the help of special diagnostic equipment, the service technician can easily determine the existing breakdown and eliminate it in a short time.

The box allows you to reduce the lack of understeer of the car by compressing the clutch packs in the right turn, and in the left turn there is a hydraulic lock, and as a result right wheel gets more torque

Reliability S-Tronic from Audi

At the same time, car owners need to take into account the fact that the S-tronic audi automatic transmission is not without flaws. First of all, such disadvantages include a significant complication of the design. It was possible to achieve the smoothest possible switching without breaking the power by using additional shafts and clutches. As a result, there are more moving parts inside the transmission, which, despite the use of sufficiently strong materials, are prone to breakage. In addition, car owners must take into account the fact that preselective boxes, which include s-tronic, require qualified maintenance. It is necessary to regularly change the oil in the transmission, which is carried out with a run of 40 - 50 thousand kilometers. The desire of the car owner to save on carrying out service work inevitably leads to breakdowns of the clutches and problems with the solenoids. Oil in s-tronic must be used exclusively original.

Structurally this box transmission has a slightly different design than classic automatic transmissions. For this reason, many experts in service centers simply refuse to service and repair the s-tronic automatic transmission. All of this makes it a bit more difficult to do. repair work and preselective automatic transmission service.

Many drivers know how to drive an Audi A4 automatic box. But for some, our article will serve as a small introductory lesson on the topic of studying the automatic transmission of this well-known automaker.

A bit of the history of the Audi brand.

The father and inspirer of the automotive brand Audi is Ferdinand Piech, who in 1974 took over the post of head of the department promising developments companies. Being not only a talented designer, but also a competent, perspicacious marketer, Pih managed 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 motorists around the world by presenting an all-wheel drive sports coupe at the Geneva Motor Show Audi Quattro . This model was truly revolutionary, because before that all-wheel drive was the privilege of trucks and SUVs. For Pich, it was a kind of experiment that fully justified his expectations. Continuing to develop the concept all-wheel drive in cars, he releases in 1984. Audi Models 90, which was developed only for sales in the US, and its European counterpart, the Audi 80.

Audi Quattro 1980

Released in 1990 year Audi 100 became the most expensive model of the automaker. This is the first car that Audi has made its presence known 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 similarly powerful brothers.

Audi 100

Thanks to new system fuel injection and others innovative solutions Audi engineers managed to remove 174 full-fledged horsepower from a 2.8-liter unit. Wherein new engine kept more power even at high rpm.

New representative in the lineup

Continuing to conquer the elite segment of the car market, the automaker produces in 1994 Audi sedan A8. heavy and powerful car executive class was popular due to the increased stability (and hence safety), which was provided by the same all-wheel drive.
In 1996, the company gave the world compact car Golf class - 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 ready-made VW Golf platform. However, thanks to the sporty style and high quality interior, the class of the car turned out to be a step higher, which brought it closer to competitors from Mercedes and BMW.
For a long time, Audi did not offer anything worthy to SUV lovers, while the company's competitors already offered their customers several models of cars of this class. The Q7 SUV, which appeared in 2005, made up for this delay by instantly gaining popularity among admirers of giant cars.

Model A4.

The successor to the Audi 80, which was produced from 1986 to 1994, is the A4 model, which entered the series from November 1994. The car has acquired a more rapid outline of the body, and the magnificent interior of the cabin conquers with its comfort. Along with this, the new model has a number of improvements regarding passive safety: the car holds a blow to the side pillars better, to basic configuration added two side airbags (in addition to two front)

Audi A4 1994

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, thanks to which it is completely protected from corrosion. The proof of reliability and quality is the 10-year warranty on the body, which is provided by the manufacturer.

Models with gasoline engine equipped with Tiptronic, which allowed you to shift gears and manual mode. This option allows experienced driver show your skills.

Automatic transmission for Audi A4.

Currently, the Audi A4 uses two models of automatic transmission:

• "AG-4" for a naturally aspirated four-cylinder engine developed by VW;
• "5 HP 18" for six-cylinder engine(developed by ZF).

New Audi A4 s automatic transmission gear

Both models are controlled by an electronic-hydraulic method. The inclusion of gears depends on the following parameters:

• engine speed;

In addition to input parameters, control takes into account:

• the driving style of the driver (having recognized it, the machine independently sets the gearshift points);
• terrain (shift mode on a mountain road will be different from the mode on a flat road).

How to operate this automatic transmission.

• Starting a car from a place. As soon as you start the engine, put the car on the brake, and only after that move the selector lever from position P or N to the range of motion you need. Otherwise, your vehicle will start to move at low speed.
• Under no circumstances depress the brake and accelerator pedals at the same time. Under normal conditions, the automatic transmission should be in the “D4” position all the time.
• Operate the accelerator pedal smoothly, without jerking. In this case, the automatic transmission will shift to higher gears quickly, thereby ensuring low fuel consumption. Use ranges "2" "1" only in those cases when you need to make quick engine braking or eliminate unnecessary shifts of the machine to higher gears.
• Kick-down mode. When not high speed you can go to lower rung by depressing the accelerator pedal all the way down. This will allow you to use the full power of the engine to accelerate the car.
• Vehicle stop. When the car is stopped, the selector lever may remain in one of the ranges of motion. The engine will run at idle.

Gearshift selector Audi A4

• At the moment of stopping on a slope, if one of the ranges of motion is enabled on the automatic transmission, and the car is held by the brake, do not increase the crankshaft speed. Switch off the engine during a long stop.
• Maneuvering. When maneuvering in small areas (garages, parking lots, etc.), use the mode with the accelerator pedal fully lowered. Adjust the speed by lightly pressing the brake pedal. Never press the brake and accelerator pedals at the same time.

Auto box diagnostics.

There are many methods for diagnosing an automatic transmission. Consider the main ones that allow you to assess the state of the automatic transmission.

• Oil condition and level.
• The level is checked with a dipstick with risks applied to it. The oil should be pure red with no burning smell. If the oil is drained into a separate container, then when it is mixed, whitish streaks should not remain.

Engine compartment Audi A4 with V6 engine

Ready time. Warm up the vehicle to normal idle. Standing on the brake, switch N-> D and N-> Dh and note the time before the push (the moment the machine is turned on). It should not exceed 1 second. Now switch N->R and note the time again. You should get less than 1.2 seconds. If the time intervals are higher than indicated, then this means the wear of the friction clutches.

Diagnostics on the road

1. Choose a straight section of road.
2. Check the position of the accelerator and its indication on the instrument panel.
3. With the selector in D, alternately accelerate and decelerate the car at half and full throttle. Make sure you are switching 1->2, 2->3, 3->4 and 4->3, 3->2, 2->1.
4. While driving in fourth gear, shift the selector to position 5 and check that the shift 4->3 occurs immediately.
5. Enter Dh mode. See if there is any switching on 1 and 4, and how the switching 2->3 and 3->2 is going.
6. While the car is moving in gears 2, 3, 4, listen, the automatic transmission may be buzzing.

Diagnostics by codes. There is a diagnostic connector under the hood of your car. Connect the jumper pins TAT ​​and GND and turn on the ignition. The HOLD lamp should light up once for a few seconds and go out. If after that it continues to flash in pulses (short or long), your car's automatic transmission needs to be repaired.

Planned Maintenance Audi A4

Diagnosis 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 box automatic 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 the mechanics, but to the electrician of the machine. You can talk about how much it costs to repair an automatic box only after the volume and complexity of the work has been determined.

Most common cause failure of the machine is a banal negligence in relation to timely maintenance. For example, if the oil and oil filter were not changed on 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 torque converter sleeve;
• The bushing rotates, 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 change) will be about 3,000 rubles.

Increasingly popular among motorists. If abroad the concept of "variator" does not raise questions, then domestic motorists not used to cars with this kind of gearbox. Therefore, now we will tell you what the variator is on the Audi A4 - 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 are more likely to change to cars with CVT, gasoline efficiency, lack of jerks when driving and other factors provide high level comfort.

[ Hide ]

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 CPT presents stepless box gears.

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. Such 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 an 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 is 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 even in this case, the official dealer will not carry out repairs, but will offer the car owner 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 wrong gear ratio block;
• 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 transmission 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 lubricating and viscosity characteristics must be as required by the manufacturer. Otherwise mechanical part The CVT will fail earlier and repair will not help here.

After starting the engine, before turning on one of the stages, press the pedal foot brake. Otherwise, the vehicle will begin to “creep.” Never press the accelerator and foot brake pedals at the same time.

Selecting gear D with the control lever, you have switched the gearbox to economy driving mode. You can almost always drive in the D stage.

When you gently press the accelerator pedal, early switching on transmissions from economical consumption fuel. Manual switching steps are necessary only in exceptional cases. Choose 3, 2 and 1 only when you want to avoid switching to more high gear or additional braking by the motor is required.

As soon as it allows traffic situation, select D again.

Automatic transmission

Automatic transmission control lever positions P, R and N

R= parking. The front wheels are blocked. Translation only when the vehicle is stationary and the hand brake is applied.

R = reverse. Switch on only when the vehicle is stationary.

N = neutral position or idling.

The automatic transmission control lever can only be moved out of the P position with the ignition on and the foot brake pedal depressed.

The engine can only be started in position P or N. When starting in position N, depress the foot brake pedal or engage the manual parking brake.

Do not press the accelerator pedal while shifting gears.

Stage D

D = constant position for normal driving conditions in gears 1 to 4.

After starting the engine and engaging D, the transmission always operates in economy driving mode.

Step 3

3 = position for driving conditions in gears 1, 2 and 3.

Stage 2

2 = position for driving in 1st and 2nd gears, e.g. on a mountain serpentine; there is no shifting to 3rd and 4th gears.

Stage 1

1 = load stage for maximum braking force e.g. on steep slopes; no shifting above 1st gear.

Electronic Driving Modes

Sport driving mode, the transmission shifts gears at more high frequencies motor shaft rotation:
press the S button (lit).

Economy mode, gearbox changes gears at lower engine speeds: press button S again.

Starting assistance: press the button.

Engines X 18 XE,X 20XEV.X 25 XE1: automatic neutral switch automatically shifts the gearbox to position N to reduce fuel consumption, for example, during stops at traffic lights. Automatic switching in the neutral position is carried out if:

– the automatic transmission control lever is in position D, 3, 2 or 1 and
- depress the foot brake pedal and
- the vehicle is stationary and
– there is no pressing an accelerator pedal.

As soon as the brake is released or the accelerator pedal is pressed, the vehicle starts moving normally.

After starting a cold engine, the control program operating temperature quickly brings the temperature of the catalyst to the value necessary for optimal reduction of the content of toxic substances in the exhaust gases, by delaying gear changes (at higher engine speeds).

Adaptive programs are programs that automatically adjust gear changes to traffic conditions such as when towing a trailer, when heavily loaded and on slopes.

Assistance when pulling away

With difficulties in slippery roads to start off, press the button, turns on in Р, R, N, D, 3 (switch on indicator - ). The car will move in 3rd gear.

The traction help is deactivated by pressing the button again.

In addition, it is possible to turn off by:

– manual selection of steps 2 or 1;
– turning off the ignition.

Kickdown - sharp pressing all the way down on the accelerator pedal

Pressing the accelerator pedal to the stop: at a speed below a certain value, the box switches to more low gear. Used for acceleration using full power engine.

Additional engine braking

To use the braking functions of the engine when descending, turn on 3, 2 or, if the situation requires it, 1 in a timely manner.

Particularly effective inhibitory action in gear 1. If engaged at too high a speed 1, the transmission will continue to operate in 2nd gear until the point of transition to 1st gear is reached by, for example, braking.

Stop

The enabled stage when stopped with the engine running can be saved.

When stopping on slopes, be sure to apply the hand brake or depress the foot brake pedal. To prevent overheating of the transmission, do not keep the vehicle in place in the engaged gear by increasing the engine speed.

At long parking, for example, in traffic jams or on railway crossing, stop the engine.

Before leaving the vehicle, first apply the handbrake, then shift to P and remove the ignition key.

The ignition key can only be removed from the ignition lock when the transmission control lever is in position P.

"Swinging"

In order to rock a car stuck in sand, mud, snow or a ditch for further movement, you can switch the control lever between D and R with a lightly depressed accelerator pedal. Keep the engine speed as low as possible and avoid sharp pressing the accelerator pedal.

The method described above should be used only in exceptional cases.

Precise maneuvering

For precise manoeuvres, such as when parking the car, driving into a garage, etc., you can use the "crawl" method by releasing the foot brake pedal.

Never press the accelerator and foot brake pedals at the same time.

Malfunction

The signaling device burns at the included ignition. If it does not go out after starting the engine or lights up while driving, then there is a malfunction in the automatic transmission.

If the vehicle is equipped with a Multi-info-display, the display shows the fault message "Automatik Getriebe" ("Automatic transmission").

The gearbox no longer shifts automatically.
You can keep moving. Shift gears 1, 3 and 4 manually using the gear lever:

1 = 1st gear,
2 = 3rd gear,
3 = 4th gear,
D= 4th gear,
N= neutral (idle),
R= reverse,
R= parking.

Have the cause rectified by an authorized Opel workshop. The self-diagnosis algorithm integrated in the system allows you to quickly find the cause of the malfunction.

Power failure

Power failure, e.g. due to a dead battery. In the event of a power failure, it is impossible to withdraw the automatic transmission control lever from position P.

Unblocking:

1. Apply the hand brake.
2. Raise the cover on the raised part of the floor between the front seats and turn it 90° to the right.
3. Press the pawl forward with a screwdriver and remove the automatic transmission control lever from position P.
4. Replace the cover on the protruding part of the floor between the front seats and fix it.

Retransfer to position P again will lock the lever. The cause of the power failure must be repaired by an authorized Opel workshop.

The love of our motorists for representative German sedans is truly boundless. And if someone does not have enough funds for new car, then he will certainly postpone and sooner or later, but the "German". But does it make sense? After all, not only are executive cars expensive in themselves, but they also do not provide for their own repairs and maintenance. Or is it not so scary? Let's try to understand this using the example of the Audi A6 in the body of the C6, which, without any exaggeration, can be called one of the most popular cars in this class.

Appearance of the Audi 6 in the back of the C6

In our review, we will focus not on the advantages of the Audi A6 C6, which abound, but on the description possible problems that may arise from the owner of a used German car.

Problems with the body and interior of the Audi A6 C6

To Audi body A6 C6 no complaints. Cars of this brand have long been famous for the fact that. But in the cabin, which is quite unexpected, "crickets" can live. And let not so many elements create extra sounds(most often it is the lining of the central pillars and the armrest between the front seats), but for a car of this class, even this seems like overkill. Although there are no complaints about the quality of finishing materials. Even on the oldest cars, you won't see worn leather trim.

Be sure to check the condition of the headlights and rear lights. The headlights themselves can fog up due to moisture getting into them, but this problem fades against the backdrop of problems with LEDs on the restyled Audi A6 C6. LEDs look very nice, but they do not differ in durability. And if at least one LED burns out in the headlight, then the entire “eyelash”, which has long become a signature element of this particular model, stops burning. Also check the operation of the headlight washers. If the previous owner rarely used it, then it is possible that the washer nozzles have already turned sour.

Engine problems

Audi A6 C6 gasoline engine

Audi A6 C6 engine

There were a lot of engines for the Audi A6 C6, but gasoline units with direct injection FSI fuel (2.4; 3.2; 4.2 liters) is better to bypass. aluminum block these engines has special coating, which over time under the action high temperatures begins to collapse, which leads to scuffing on the walls of the cylinders. As a result, oil consumption increases, the engine starts to work more noisily and with increased vibrations. The power is thus reduced. At the same time, focus on some kind of mileage when buying a car with FSI engine will not work.

Some owners encountered the first problems only after 200 thousand kilometers, but if you look at the statistics, it turns out that on average these nursed about 120-150 thousand kilometers. And besides the short-lived coverage, there are enough problems. The same unit with a volume of 3.2 liters is notorious for the fact that the chain in its gas distribution mechanism, after 100-120 thousand kilometers, began to stretch, which required its immediate replacement. And this, due to its not the best availability, is quite expensive.

So it’s better to look at cars with a 2.8-liter gasoline unit that develops 190 Horse power. This unit is also very technologically advanced, but there are fewer problems with it. Although he also loves quality and timely service. Without it, for trouble-free long work don't even count.

Video: Resale project: review of the Audi A6 3.2 quattro

But it is even better to find a car with a simple and reliable atmospheric three-liter gasoline engine. But keep in mind that this unit was no longer installed on cars that were produced after 2008. In it, every 100 thousand kilometers will have to change the belt in the gas distribution mechanism. And this is quite difficult to do, because to replace it you have to disassemble almost half of the front of the car.

Also on this engine every 90 thousand kilometers you will have to change the coils, and after 150 thousand kilometers you will have to deal with leaking oil seals and antifreeze leaks from under the head gasket. Around the same mileage, the engine begins to consume oil. So don't forget to keep an eye on it. But in any case, it is this engine that seems the best choice for used Audi A6 C6.

Audi A6 C6 diesel engine

Diesel engines on the background gasoline units look even more interesting, but hardly anyone can guarantee that our diesel fuel they will work flawlessly. Probably very expensive fuel injectors for you will turn into consumable. Yes, and run diesel vehicles from Europe are very large. So be prepared that immediately after buying an Audi A6 with turbodiesel engine you will have to change an expensive turbine, which usually fails by the mark of 250-300 thousand kilometers. By the same time, the chain in the gas distribution mechanism will require replacement. So in the case of a used Audi A6 with a diesel engine, saving on fuel will not work. All savings at once will be crossed out by one serious breakdown.

Audi A6 C6 gearbox problems

Tiptronic Audi A6 C6
Among the gearboxes offered for the Audi A6 C6, preference should be given to automatic transmission tiptronic. It is quite reliable, although some owners complain that the transition from first to second gear is a little jerky. But this is not a malfunction. Official dealers claim that this is a feature of the operation of this gearbox. But if the jerks during switching are too large, then say goodbye to this instance without regret, since everything goes to the point that it will need to replace the valve body. Usually such a replacement is required after a run of 100 thousand kilometers. Also, in the "automatic" every 80 thousand kilometers, you will have to change the oil, although the manufacturer claims that it is designed for the entire life of the car.

Multitronic Audi A6 C6

The Multitronic CVT is slightly less reliable. He is afraid of sluggish congestion, because in such conditions the clutch discs are very hot, which clearly does not extend their life. Also, be prepared to change the oil in the variator every 40-60 thousand kilometers, and if the car spends most of the time in urban traffic jams, then the variator itself may require repair by a run of 100 thousand kilometers. Although in more benign conditions, it can withstand 250 thousand kilometers without problems.

The manual gearbox on the Audi A6 C6 is also quite good, but it is hardly appropriate at all in a car of this class. So with all its pluses, you can say goodbye to it without regret.

Video: 2007 Audi A6 C6 / Choosing a used car

Suspension Audi A6 C6

The suspension of the Audi A6 in the body of the C6 is reliable. upper arms and steering tips can withstand 100 thousand kilometers without problems. 20 thousand kilometers more withstand wheel bearings and stabilizer bars. After another 40 thousand kilometers, you will have to change the shock absorbers. The rest of the "consumables" will require replacement only when the mileage exceeds 200 thousand kilometers.

About small claims and steering. On some cars, the steering force regulator failed, but this problem cannot be called widespread.

Brake system and electrical problems

But the braking system could be more reliable. If an electromechanical brake is installed on your car, then be prepared that after 100 thousand kilometers it will fail. The same service brake system no different from that on cars of other brands. Every 30-40 thousand kilometers it is necessary to change the front brake pads. Rear brake pads last twice as long.

And finally, it is worth talking about problems with the electrician. There is a lot of it in the Audi A6 C6, so from time to time you will have to mess with it. Even a banal battery replacement will require qualified intervention. And all because of the huge number of electrical units, all information from which is transmitted to the head on-board computer, which provides correct work all systems.

Still want to become the owner of a used, but still prestigious German sedan or station wagon? If yes, then be prepared to pay a lot of money for its maintenance. And the more high-tech components in your car, the higher your cost of maintaining the car. But the pleasure of Audi ownership A6 C6 is great.

Conclusion:

So, if the desire to own a "six" is still great, look for an instance with a three-liter gasoline engine and a Tiptronic "automatic". It is this option that can be considered optimal.
