Audi A7 4G

Fashion for sports sedans, the silhouette of which resembles a coupe, imposed Mercedes with the help of the CLS model. Audi didn’t want to be left behind and in 2010 introduced the A7. Most of the car enthusiasts were delighted with what they saw. No one will deny him elegance and chicness. The Audi A7 is massive and stocky due to its proportions. The length is 4.97 m and the width is 1.91 m. With a relatively long and wide silhouette, the height is only 1.41 m. All this is complemented by a dynamic design and a small glass area. There is plenty of room for people sitting in front. Tall passengers on the back sofa will complain about the lack of space over their heads due to the low line of the sloping roof. The sporty character of the Audi A7 is emphasized by the rear spoiler, which automatically retracts when speeding 130 km/h and retracts when speeds fall below 80 km/h. The spoiler can also be controlled manually using the buttons on the front panel. There is no shortage of space in the trunk. It's 535 litres. Most family cars do not have this result. With the rear seats folded, a flat floor is formed, and the volume increases to 1390 liters. Interior decoration materials are a sample of quality. The front panel is made in accordance with the basic principles of ergonomics. At the top of the center console there is a retractable 8-inch screen of the MMI system, which can be used, among other things, to change the characteristics of the suspension, transmission and steering. The A7 can also be equipped with a system for displaying important information on the windshield. In May 2014, a restyled version was presented. It features narrower headlights, a wider grille and modified bumpers. The rear lights were modified and the exhaust pipes were rectangular.

Engines

For the drive of the Audi A7 used three petrol and two diesel engines:

2.0 TFSI – R4 2.0 l / 252 hp (since 2014)

3.0 TFSI – V6 3.0 l / 299 hp and 333 hp (since 2014)

All engines have a chain-type timing system drive, which, unfortunately, sometimes requires attention after 100-150 thousand km. In all units, the chain is located on the side of the gearbox, so you have to remove the engine to access it. This significantly increases the cost of replacement, which reach 100-150 thousand rubles. 2. 0 TFSI, which appeared after restyling, has not been widely distributed, and the runs are not yet large. At least, cases of oil and gas, as in weaker analogues, in this version of the engine are not recorded. 2. 8 FSI in the past (as in the Audi A6 C6) often suffered from bullies. After it was finalized, but unpleasant episodes still surfaced. In 2012, Audi stopped offering the engine. But after a series of trials and improvements, the engine returned to the list of available in late 2012. One of the disadvantages of 2.8 FSI - clogged channels of secondary air, designed for blowing catalysts (after 150-200 thousand km). 3.0 TFSI - has become the most common. For the engine boost, not a turbocharger is used, but a mechanical supercharger of the Roots type, located in the collapse of the block. The main problem 3.0 TSFI - bullies on the walls of the cylinders. The disease affected cars assembled before the end of 2013. At the end of 2013, modified engines with more durable spraying on the cylinder walls appeared. But annoying troubles still happened.

Transmission

The Audi A7 came with front-wheel drive or all-wheel drive Quattro. In all-wheel drive versions, the usual Torsen is no longer used. The new center differential is able to distribute the torque between the front and rear wheels in a wider range - up to 85% back and up to 70% forward. In normal mode, 60 percent of the thrust is transmitted to the rear wheels. As an option, an active rear differential was offered, twisting the external wheel in a turn. The front-wheel drive variant was equipped with a Multitronic continuously variable wedge-chain variator, and with all-wheel drive a 7-speed robotic transmission with a dual clutch of the “wet type” S-tronic. With the most powerful bi-turbodiesel worked 8-band automatic transmission Tiptronic company ZF. It was also widely used in the A7, intended for the American market. Almost all Audi A7s on the secondary market are equipped with the S-Tronic robot. Most often, automated boxes of pre-restyling versions were brought down - mechatronics failed. It should be changed in the collection with a clutch, for which you will have to pay more than 120 000 rubles. Some services have learned to repair mechatronics (about 30 000 rubles). In addition to the mechatronics itself, its connector (8,000 rubles) could also fail. In addition, sometimes the oil filter body leaked, or the sealing ring of the filter body squeezed out. After restyling, the mechatronics were refined, and unpleasant cases at early runs began to occur much less often. There are many S-Tronic, which have passed over 150-200 thousand km, without repairing the mechatronics and clutch.

Walking

Multi-link suspension is used on the front and rear axles. As an option, air suspension and a clamped spring S-Line were offered.

Usually, attention should be paid to the front suspension. After 50-100 thousand km can sound hub bearings (4 000 rubles for an analogue), or knock the lower levers (5 000 rubles for a lever).

The steering uses an electromechanical amplifier built into the steering rack. Unfortunately, Reika sometimes fails. In some cases, it was possible to revive it after flashing the control unit. If the update did not help, the dealers resorted to replacing the rake - 200-300 thousand rubles.

Few people can repair the rail so far, but even after repair it will not last long. Used or restored rake will cost 70 000 rubles. A new rail can be found for 150 000 rubles, and the replacement work will require another 6 000 rubles.

Body and salon

A number of body parts are made of aluminum - the hood, front wings and doors. With large runs in individual copies, chips are formed on the rear wheel arches.

From time to time, the lock of the gas opening locks. Over time, water enters the castle, which finishes the motor. The first symptoms are an unopening hatch in the cold. It then stops opening at any temperature. The cost of a new motor is about 2 000 rubles.

Moisture over time kills and not sufficiently sealed sensors (4,000 rubles per piece) in the handles of the keyless access system Keyless. If one sensor fails, the others stop working.

In winter, mirrors sometimes turn outward when unfolding. The only way out is to turn off the automatic folding of mirrors during frosts.

Sometimes there are problems with the air conditioning system. As a rule, it is all about an inexpensive refrigerant pressure sensor (2,000 rubles), located behind the radiator grille.

On the A7 of the first years of release could crunch gears drive mechanism monitor. Dealers changed the block for a new one under guarantee.

The Audi A7, like any modern high-tech car, is literally stuffed with electronics that start to fail from time to time. Almost always bring the equipment to life after turning off the ignition or rebooting the MMI.

Engines

• The main problem 3.0 TSFI - bullies on the walls of the cylinders.
• The catalyst begins to gradually collapse, which will lead to the ceramic crumb getting into the cylinders, which in turn will provoke the appearance of bullies and subsequent overhaul of the engine.
• Replacing faulty catalysts with universal analogues will require about 23,000 rubles.
• In addition, owners of 3-liter versions met with malfunctions of the thermostat (4 000 rubles) – antifreeze disappeared without a trace.
• The leak arises from under the upper pallet, the bolts of which are pulled out over time.
• To eliminate the leak, it is necessary to remove the engine, so the price tag will be about 70,000 rubles.

• In addition, sometimes the oil filter body leaked, or the sealing ring of the filter body squeezed out.
• km, without repair of mechatronics and clutch.
• Despite complaints of tremors, kicks and lapses in traction, no real cases of repairs have been noted.
• You do not have to look too early in the service for repairing the box and owners of the A7 with a CVT.
• For this, two types of oil are needed – 6 liters for mechatronics (7 200 rubles) and 5 liters for mechanical parts (6 500 rubles).
