Increasingly popular among motorists. If abroad the concept of “variator” does not raise questions, then domestic motorists are not accustomed to cars with this type of gearbox. Therefore, now we will tell you what a CVT is on an Audi A4 - you can also evaluate the reviews of other motorists in this article.

The main advantage of a variable speed transmission (hereinafter referred to as CVT) is the ability to efficiently use engine power compared to other types of gearboxes. Russian and Ukrainian car enthusiasts more often switch to cars with CVT; gasoline efficiency, lack of jerks when driving and other factors provide a high level of comfort.

What type is on A4 and A6?

As stated above, the popularity of CVTs is growing, manufacturers vehicles They are often installed on self-produced CVT cars. Thus, the manufacturer installs Multitronic CVTs on Audi A4 and Audi A6 cars. This type The gearbox is a continuously variable transmission.

CVT Multitronic consists of:

• multi-disc wet clutch;
• planetary box device;
• intermediate transmission component;
• direct 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 its gearboxes. This engineering solution made it possible to increase the range of gear ratios. As a result of the operation of the links different sizes, in CVT, a reduction in the noise of the gearbox as a whole has been achieved.


According to the manufacturer, the operation of this type of gearbox allows for maximum driving dynamics and a high level of engine fuel economy. What can we say about comfort? The consumer properties of these CVTs are quite high; they are installed on premium cars “Audi A4” and “Audi A6”. On these types of transport, the manufacturer installs the CVT model “Miltitronic 01J”.

Is this variator subject to repair and where should it be repaired?

Not everything can be perfect as we would like. As they say, “there is always a fly in the ointment.” We are talking about the electronic unit - its location in the CVT unit has one huge drawback. When the CVT operates, heavy loads are placed on the block. This is due to heat transmission fluid. Therefore, the electronics unit fails more often.

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 not only lose a lot of time, since such a device is usually not in stock and is ordered from abroad, but also a lot of money. But, if the car is still under warranty, the dealer can change electronic unit for free.

This type of breakdown is the most common; it can be called a disease for Multitronic CVTs. The metal chain breaks less often. But even in this case official dealer will not carry out repairs, but will offer the car owner to replace it.

You can contact specialized service stations that repair control units. Diagnostics on the computer shows a list of errors when the unit malfunctions:

• 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 gear ratio of the block;
• 17134 P0750 – the ABS/EDS device has failed;
• 17137 P0753 – no electrical circuit signal;
• 18201 P1793 or 18206 P1798 - the output speed device has failed - in the event of such a breakdown, the signal is incorrect or completely absent;
• 17090 P0706 - the controller position device has failed - an incorrect signal is recorded;
• 18226 P1818 or 18221 P1813 – malfunctions in the electrical circuit have been detected.

The above errors appear like this:

• the vehicle moves jerkily when the speed increases;
• the car jerks when changing gears;
• from time to time it becomes impossible to engage reverse gear;
• sometimes, especially for the Audi A6, the car cannot be removed from position P (parking mode).

If you encounter 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. DIY repair at home is not allowed, since this requires at least the necessary knowledge and expensive equipment that is not sold in stores.

The electrical box itself is located behind the rear cover of your CVT. But keep in mind that if this device is being repaired, you will also have to spend money on gear oil. Filling with fake or counterfeit products is under no circumstances allowed, so you will have to purchase original products. Otherwise, forget about the normal operation of the gearbox. Liquid marked G 052 180 A2 (G052180A2) can be purchased from a dealer or ordered online.

Nowadays there are many types of expensive and quality oils, but you only need the original. Of course, the fluid may be good, but the lubricating and viscosity characteristics must be as required by the manufacturer. Otherwise mechanical part The CVT will fail sooner and repairs will not help here.

The car is equipped with a 5-speed automatic transmission with electronic control. Switching to higher and lower gears is carried out automatically.

For reasons of fuel consumption and security environment, on some modifications the transmission is designed so that the maximum speed of the car is achieved only in the “S” position.

The gearbox is also equipped with a tiptronic system. This system gives the driver, if desired, the ability to manually change gears.

Switching to higher and lower forward gears is carried out automatically.

Pulling away

• While holding down the lock button (on the control lever), move the control lever to the desired position, for example, position D, and release the lock button.
• Wait until the automation switches on, creating a forceful connection between the gearbox and the drive wheels (at the moment of switching on, you will feel a slight push).
• Release the brake pedal and press the accelerator pedal.

Short stops

• Hold the car with the brake pedal, for example, at traffic lights.
• Do not press the accelerator pedal while doing this.

Parking

• Press and hold the brake pedal.
• Fully apply the handbrake.
• While holding down the lock button, move the control lever to the “P” position and release the lock button.

The engine can only be started when the control lever is in the “P” or “N” position.

When parking on level ground, it is enough to set the control lever to the “P” position. If the road is sloping, first tighten the parking brake all the way and only then move the control lever to the “P” position. This reduces the load on the locking mechanism and makes it easier to release the control lever from the “P” position.

Attention.

• When shifting before moving off, do not press the accelerator pedal - there is a danger of an accident!

Control lever positions

This section describes each control lever position.

The actual position of the control lever is indicated accordingly on the displays of the instrument cluster.

P - parking lock

In this position, the drive wheels are mechanically blocked. The parking lock may only be activated when the vehicle is stationary.

To set the control lever to the “P” position and release it from this position, press the lock button (on the control lever) and at the same time the brake pedal.

R - gear reverse

When the control lever is placed in this position, reverse gear is engaged.

Reverse gear may only be engaged when the vehicle is stationary and when the engine is running in idle speed.

To set the control lever to the “R” position, press the lock button and the brake pedal at the same time. When the ignition is turned on and the control lever is in the “R” position, the reverse lights come on.

N - neutral position (idle position)

This position is the idle position.

D - main position when moving forward

In this position, shifting to higher and lower forward gears is carried out automatically, depending on engine load, speed and dynamic shift program (DSP). To move the control lever from position "N" to position "D" when the speed is less than 5 km/h or the vehicle is stationary, you must press the brake pedal.

To enable manual adjustment gear ratio Under certain driving conditions, under certain circumstances (for example, when driving in the mountains or with a trailer), it may be preferable to temporarily switch to the manual shift program.

S - sport position

Set the control lever to the "S" position when driving in sport mode. Later switching to higher stages allows full use of engine power reserves.

To move the control lever from the “N” position to the “S” position when the speed is less than 5 km/h or the vehicle is stationary, press the brake pedal.

Attention

• While driving, never set the control lever to the "R" or "P" position - risk of accident!
• Regardless of the selected driving mode (except for “P” and “N”), when the engine is running, hold the car with the foot brake, since even in idling mode the kinematic connection of the engine with the wheels does not completely disappear - the car “crawls.” When the car is stationary with the mode turned on movement, do not inadvertently add gas (for example, by hand in engine compartment). Otherwise, the car will immediately begin to move, possibly even with the parking brake- danger of accident!
• Before opening the hood and starting work with the engine running, move the control lever to the “P” position and apply the parking brake until it stops.

Note

• If you inadvertently move the control lever to the “N” position while moving, before returning to “D” or “S” mode, release the gas and wait until the speed drops to idle.
• For reasons of fuel consumption and environmental protection, on some versions the transmission is designed so that the vehicle's maximum speed is achieved only in the "S" position.

Control lever lock

Locking the control lever prevents the vehicle from inadvertently engaging the range of motion and thereby preventing the vehicle from moving unintentionally.

Cancellation of blocking is carried out as follows:

• Turn on the ignition.
• Press the brake pedal and hold down the lock button at the same time.

Automatic control lever lock

When the ignition is turned on, the control lever is locked in the “P” and “N” positions. To release it from these positions, press the brake pedal. As a reminder to the driver, when the control lever is in the “P” and “N” positions, the following indication appears on the display:

"BIEM EINLEGEN EINER FAHRSTUFE IM STAND FUSSBREMSE BETATIGEN" (when selecting the driving mode of a stationary vehicle, press the brake pedal).

In addition, the automatic control lever locking symbol gj lights up on the control lever flap.

At a speed of approximately 5 km/h and above, the locking of the control lever in the "N" position is automatically canceled.

When the control lever is quickly moved through the "N" position (for example, from the "R" position to the "D" position), the control lever is not locked. This will give, for example, the ability to “rock” a stuck car. If the control lever is in the “N” position for more than 1 second when the brake pedal is released, it is blocked.

Lock button

The control lever lock button prevents the control lever from being inadvertently moved to certain positions. When this button is pressed, the control lever is released. The figure highlights the positions at which it is necessary to press the lock button.

Locking the key in the ignition switch

After turning off the ignition, the key can be removed from the lock only when the control lever is in position “P” (parking lock). After removing the key from the lock, the lever is locked in the “P” position.

Kick-down device

The Kick-down device allows for maximum acceleration.

When you sharply press the accelerator pedal and pass the point of resistance, the automatic switches, depending on the revolutions and speed, to a lower level. Switching to the next higher stage occurs immediately after reaching the maximum engine speed corresponding to this stage.

Attention. Remember that on slippery road the drive wheels may slip when the kick-down device is activated - danger of skidding!

Dynamic Shift Program (DSP)

The automatic transmission is controlled electronically.

The automatic transmission is controlled electronically. Switching to higher and lower levels is carried out according to the movement programs stored in memory.

If you drive with restraint, the automatic system selects an economical switching program.

With a temperamental driving style with sudden acceleration and frequent changes in speed, using maximum speed or after sharp pressing on the accelerator pedal (Kick-down), the automatic system operates in a range of sports programs. A late transition to higher stages allows you to fully utilize the engine power reserve. Switch to low gears carried out at more high speed engine.

Selecting the optimal driving program for specific conditions is a continuous process. However, regardless of this, you can switch to a sportier program by sharply pressing the accelerator pedal. In this case, the transmission switches to a lower gear corresponding to the actual speed of movement, providing the possibility of dynamic acceleration (for example, when overtaking) without the need to sharply press the accelerator pedal all the way. After switching back to a higher gear and in the appropriate driving mode, operation according to the original program is restored.

The mountain program controls gear selection on uphill and downhill slopes. Thanks to this, there is no need to shift when driving uphill. Pressing the brake pedal when driving downhill switches to a lower gear. As a result, you can brake with the engine without resorting to manual shifting.

Tiptronic mode

The tiptronic system also gives the driver the option of manual gear shifting.

Switching to manual mode

• Push the control lever out of position "D" to the right. When manual mode is engaged, “5 4 3 21” appears on the display, highlighting the currently engaged gear.

Upshifting

• When the control lever is moved forward (in the tiptronic position), a shift into higher gears (+) occurs.

Downshifting

• When the control lever is moved back (in the tiptronic position), a shift to lower gears (-) occurs.

You can switch to manual mode both while driving and while parked.

When accelerating at 1, 2, 3 and 4 stages, the box will automatically switch to the next higher stage shortly before reaching maximum engine speed.

When switching from a higher gear to a lower gear, the automatic system will switch only after it becomes impossible to increase the engine speed at different intervals.

When the kick-down device is operating, the transmission switches to the next lower gear depending on the speed and engine speed.

Emergency program

In the event of a system malfunction, the automation switches to the emergency program.

If the system malfunctions, the automation switches to the emergency program. This is signaled by the lighting up or extinguishing of all segments on the indicator panel at once.

In this case, the control lever can be moved to all positions. However, in positions "D" and "S" the 4th stage will be activated.

It is also possible to engage reverse gear "R". However, the electronic reverse gear lock is disabled when operating in emergency mode.

In emergency mode, the manual shift program (tiptronic) is switched off.

When shifting the gearbox to emergency mode Contact Audi as soon as possible to have the fault rectified.

Tiptronic steering wheel

The buttons located on the steering wheel also give the driver the opportunity to manually change gears.

Upshifting

• Press the top side of one of the keys (+).

Downshifting

• Press the underside of one of the keys (-).

The gear shift keys on the steering wheel are in operating mode when the control lever is in position "D", "S" or in the manual shift program (tiptronic).

Of course, manual gear shifting is also possible using the center console control lever.

Audi A6 gearbox repair

Audi A6 – new sedan fifth generation of German production, introduced in 2018. By design new model most resembles the Audi A7 Sportback, the car is built on the same modular platform MLB Evo. The car is equipped with the latest electronic systems: special radars, video cameras, infrared sensors provide almost complete automatic control. The car received a wide range diesels and motors on gasoline with wide power range: maximum power gasoline engine is 340 hp, diesel – 204 hp. The updated machine has excellent driving performance and fast acceleration.

Features of gearboxes

Latest version sports sedan from Audi received several versions of the transmission: paired with gasoline engines an 8-speed hydromechanical gearbox is installed machine, diesel versions The engines work with a seven-speed dual-clutch automatic transmission. Classical mechanics without electronic control for the latest generation of cars was not available, although it was provided to buyers in previous generations.

In the previous restyled version of 2014, the car, in addition to robotic gearbox, a 6-speed gearbox was installed manual transmission transmission In Russia, manual transmissions are always in high demand, since this type of gearbox provides full control of the car and at the same time is the cheapest. Installing mechanics allows you to reduce fuel costs and not depend on capricious electronics - the car becomes more reliable and economical.

A prerequisite for long-term trouble-free operation of a manual transmission is proper maintenance, but it is cheaper than for automatic and robotic transmissions Oil change it is enough to carry out once every 70 thousand km, and it is enough to small quantity transmission fluid.

Possible causes of gearbox problems

The mechanics are characterized by maximum reliability; the duration of its use can reach 300 thousand kilometers and even more. This allows you to use the gearbox throughout the entire service life of the vehicle without major repairs. However, this is only possible with the right regular maintenance and following recommended oil change intervals. Flushing allows you to free the gearbox from contaminants and prevent possible malfunctions.

The following signs will indicate problems with such a gearbox:

• Notable extraneous noise. Crackling, grinding, crunching occurs when there is insufficient amount of transmission fluid in the gearbox, as well as when parts are severely worn due to high friction. During diagnostics in the workshop, it is necessary to find the cause and quickly eliminate it.
• Problems with enabling the required speed limit. It becomes difficult to move the lever to the desired position, the problem arises due to wear and tear on the components of the shift mechanism.
• Grinding or cracking sound when trying to change gear. Often it indicates a clutch malfunction; wear of the mechanism is possible within the first 100 thousand kilometers.

Professional repairs in a workshop can completely restore the functionality of the gearbox and return it to operation. Take advantage of the services of our professionals service center V Moscow.
