Audi A4 B6/B7

The second-generation Audi A4 debuted in 2000, and mass production of the model began in 2001.The Four shared the platform with the Volkswagen Passat B5. In total, more than a million copies of the Audi A4 B6 were produced in the world. Even though they are relatively old, there are no serious problems.

Engines

The Audi A4 B6 was offered with a large number of engines with a working volume from 1.6 liters (100 hp) to 3 liters (220 hp) of the “charged” S-version. The most widespread were three units: gasoline 2.0 liters ALT (130 hp), gasoline with a turbocharged 1.8 liters (150 hp - avj, 163 hp - bfb, 170 hp - amb (USA) and 190 hp - bex) and diesel 1.9 TDI (100 and 130 hp). 2 liters ALT is famous for its excessive oil appetite, coming after 100 thousand km. Only one thing calms down - the increased oil consumption, as a rule, no longer grows and averages 2-3 liters per 10 thousand km. Diesel 1.9 TDI is a reliable unit. With a run of more than 200 thousand km, most likely, you will have to pay attention to the state of fuel injectors. The supercharged 1.8T requires more attention. Interruptions in operation may occur due to loss of tightness and air sucking in the pipe connecting the air filter with the turbocharger compressor. Often, the pipe is wiped with a clamping at the turbine itself, while a whistle appears, and the engine does not hold idle turns. The turbine nurses at least 200 – 250 thousand km, and with careful operation survives up to 300 thousand km. The new turbine will cost 20-25,000 rubles, its repair will require about 10,000-15,000 rubles. The restored turbine is capable of running another 50 – 60 thousand km. Plastic tee coolant behind the engine under the influence of temperature and time warps and begins to "etat" antifreeze. The new one costs about 600 rubles, but to replace it, you will have to work hard. With a run of more than 160 – 200 thousand ## Transmission

The Audi A4 B6 was equipped with a fully synchronized 5 or 6-speed manual transmission, a 5-speed hydrotransformer automatic transmission "Tiptronic" with a dynamic DSP switching program or a Multitronic continuously variable variator with a dynamic DPR control program. "Mechanics" is very reliable and unpretentious. Clutch on cars with a 1.8T engine serves more than 160 – 180 thousand km. The new clutch set is available for 12-15 thousand rubles. Work on its replacement will require about 8-9 thousand rubles. If there is a need to replace the flywheel, then you will have to pay another 17-20 thousand rubles. Tiptronic automatic transmission is generally reliable, but when running more than 200-220 thousand km, tremors may appear during switching and slipping. The reason is friction wear. Repair will require about 40-60 thousand rubles. Multitronic was installed only on front-wheel drive versions of the Audi A4 B6. The most common ones were used before 2004. The variator requires regular oil change, otherwise the wear of the chain and cones is accelerated, which leads to "clogging" with wear products of the filters and valves of the pump box. This, in turn, causes tremors, jerks and jerks - more often when starting and stopping the car. Repair in this case will require about 70 – 90 thousand rubles. Vibration at the time of energetic acceleration is a common phenomenon when running more than 160 – 200 thousand km. The reason is the wear of the internal SRUS (tripod). Original costs about 10 thousand rubles, non-original - 4-4.5 thousand rubles. # #

The multi-link suspension of the Audi A4 is made of aluminum alloy. Native levers often live up to 150 – 200 thousand km before they start knocking. A set of new 8 levers for the front suspension will pull 20 – 25 thousand rubles for the original, and 7-15 thousand rubles for analogues. After replacement, cheap analogues serve an average of 30 – 50 thousand km, the originals step beyond the threshold of 60-80 thousand km. Brake hoses begin to give up when running more than 180 - 220 thousand km. When running more than 200-220 thousand km may require replacement of the pump brake system. When self-replacement of rear brake pads, you need to be careful, sinking the piston. It is better to do this using a special device that simultaneously presses and rotates the piston. Otherwise, it can be broken, and a new caliper is not cheap. Due to a malfunction of the stop light switch ("frogs"), the ESP icon constantly lights up, and periodically ABS. The new switch is inexpensive - only 600 rubles. On the diesel “four” there were problems with the fitting of the vacuum pump. The new pump will require 12-14 thousand rubles. But you can get rid of and a little expensive repair for 100 rubles with the help of cold welding. # # Body and salon

The body of the Audi A4 is fully galvanized with a very good paint coating. There is no hint of rust even on the first copies. The glove compartment loop is a weak point: over time, it falls off. The new glove compartment costs about 10 thousand rubles. But do not rush to buy a new one. A cheaper way to repair is to glue a broken loop onto a good glue or fasten it with screws. When running more than 200 - 250 thousand km often begin to "swim" pixels on the display of the onboard computer. The new display costs about 2.5 – 4 thousand rubles, for its installation you will need to pay another 1.5 – 2 thousand rubles. Over time, with a run of more than 200 thousand km, the buzzer of the dashboard also falls silent. The reason is the speaker's failure. #Comfort

The compressor of the air conditioner of constant rotation (continuous action) is in dire need of lubrication of the internal parts. It does not tolerate a small amount, and especially the absence of freon and oil in the system. If a leak is detected, it is necessary to immediately find the cause and eliminate it, avoiding the operation of the car. The compressor itself is not repairable, and the need to replace it arises when running more than 160-220 thousand km. The new compressor costs about 18-25 thousand rubles, and work on its replacement is 7-8 thousand rubles. Diesel Audi A4 may damage the damper pulley due to increased vibration. The new pulley will cost 6-7 thousand rubles. Over time, the heater radiator will need to be replaced or flushed. The need for this will come when in the cold time, with the engine fully warmed up, warm air will no longer be supplied to the cabin.

Due to the break of the wire in the protective corrugated wiring between the door and the body, the electrician of the rear door ceases to work, and the backlight is constantly burning in the cabin. For a similar reason (a cliff in the corrugated) the electric lock of the trunk ceases to work. In addition, the lighting of the license plate can be turned off. With proper electrical wiring, the reason is a malfunction of the electric motor of the lock. The new one costs about 700 – 800 rubles. The standard security system may stop perceiving car keys due to oxidation of contacts on the comfort unit or failure of the unit processor. # Audi A4 B7 (2004-2009)

The third-generation Audi A4 was produced from 2004 to 2007, representing a deeply modernized predecessor. The updated Audi was internally designated B7. #

The line of engines was represented by gasoline and diesel units. Gasoline: atmospheric inline fours 1.6 liters (102 hp), 2.0 l (130 hp), 2.0 FSI (150 hp), as well as a V6 3.0 l (218 hp) and 3.2 l (255 hp), and a V8 4.2 l (344 hp). Two turbocharged gasolines are 1.8 T (163 hp) and 2.0 TFSI (200 hp). The line of diesel engines is represented by seven units with a working volume of 1.9 to 3 liters, but the most widespread was the 2-liter turbodiesel with a capacity of 140 liters. with. The most common Audi A4 B7 with gasoline engines with a capacity of 2.0 liters and turbocharged 1.8 and 2.0 liters. All engines have a timing system drive using a geared belt and hydraulic valve pushers that do not require adjustment. A turbocharged 1.8 is a fairly reliable engine. a 2-liter TFSI can cause problems. His disease is the formation of production on the pusher TNVD and camshaft at a run of more than 100 - 130 thousand km. Since 2007, pushers have been improved, and their resource has increased slightly. For supercharged engines after 100 – 140 thousand km is characterized by leakage of the valve cover, the elimination of which will require about 11 – 12 thousand rubles. One of the reasons for this phenomenon is a faulty valve ventilation crankcase gases. At the same time, the oil can push not only from under the valve lid, but also into candle wells, and whistling may also appear. Ignition coils rarely serve more than 100 - 120 thousand km, starting to fail one after another. The cost of one coil is about 1 – 1.5 thousand rubles. The engine supports run at least 150 – 200 thousand km. With a run of more than 120 - 150 thousand ## Transmission

In the Audi A4 B7, you can find 5 and 6-speed manual transmissions, a Multitronic variator and a 6-speed “automatic” Tiptronic (only on all-wheel drive versions). Some owners complain about the poor inclusion of the 1st and 2nd gear when running more than 90 - 140 thousand km. Perhaps after 180-220 thousand km will have to replace the gear lever and synchronizers. Clutch, as a rule, goes at least 120 - 150 thousand km. After 120 – 150 thousand km can throw problems Multitronic due to the failure of the control unit automatic transmission. In this case, the box goes into emergency mode, and the PRNDS line flashes on the dashboard. As a rule, repairs cost little blood 15 – 20 thousand rubles. On the “automatic” ZF engineers made a miscalculation in the compatibility of the working fluid and the algorithm of the box, which leads to its rapid wear. In search of a solution to the problem situation, the configuration programs of the ECU box and the working fluids used were changed. The optimized ATF fluid has been green since March 2008, before that time it was first used yellow and then blue. Problems arose when running more than 80 - 120 thousand km - were manifested by tremors during acceleration during gear shifting. The reason for the failure is the failure of the hydraulic transformer ("donut"). The new hydraulic transformer will cost 40 – 45 thousand rubles, work on its replacement will require about 8 – 10 thousand rubles. Of course, you can save money by repairing a faulty "donut" for 5-8 thousand rubles, but it does not last long.

The front suspension of the Audi A4 B7 is four-lever, the rear - on trapezoidal levers. Contrary to popular belief, the suspension of Audi is far from gentle and on our roads stretches at least 120 – 150 thousand km. Replacing the knocked levers at once will require about 35-40,000 rubles. Stabilizer racks run about 80 – 120 thousand km, about the same stretch and sleeves of the stabilizer. Shock absorbers will require replacement when running more than 140 – 180 thousand km (2 – 4 thousand rubles per piece). After 120 - 150 thousand km often fails "frog" brakes (600 rubles). This will prompt unreasonably illuminated simultaneously ABS and ESP, which dim after re-switching off and turning on the ignition. In addition, at the same time on cars with automatic transmission, the engine thrust is significantly reduced. With a run of more than 160 – 200 thousand km, the steering rack often begins to leak. Repair it will cost 12 - 15 thousand rubles. # # Body and salon

Problems with the central lock are more often caused by the oxidation of contacts on the driver's door lock control unit or by a break in the corrugated wires connecting the body to the door. Over time, the electronic control unit of comfort systems can also blink, in this case there will be problems with the management of the central lock, mirrors, cabin lighting, windows, heated mirrors or a fuel hatch. Parking sensors begin to give up when the mileage is more than 140 – 160 thousand km. On the keys of certain models from cars of the first years of release, there were problems with Audi’s response to pressing the buttons on the key fob. In this case, you will have to replace the key with a new one, which will cost 8-9 thousand rubles for the original and 3-4,000 rubles for an analogue from China. Over time, the external linings on the door handles begin to cling, and the windshield wiper drive mechanism sours. Xenon lamps illuminate their own by 100 - 120 thousand km. Unoriginal lamp will cost 3 – 4 thousand rubles, the original – 5 – 7 thousand rubles. In the cabin of runaways A4 begins to work poorly glove compartment lock and fails fixing the lock back of the rear seats. With a run of more than 120 – 150 thousand km, the air flow control valves in the cabin begin to fail, more often the recirculation valve. The reason is because of the wear of the servo drives.

The Audi A4 B6 is the last of the Mohicans. This is a car that was designed to serve its owners for decades. Despite the decent age, there are almost no serious problems. The engines serve faith and truth, and the body firmly holds the “salt baths”. Slightly weaker on this background look multitronic variator, suspension and air conditioner compressor.

That’s the whole background of the Audi A4 B7. In general, everything is not so bad, and the probability of the occurrence of these malfunctions on one car is low. The main attention should be paid to the automatic transmission, and when choosing a turbocharged car - to the state of the turbine, remembering that 1.8 T is much more reliable than 2.0 TFSI.

• Engines: Outages may occur due to loss of tightness and air suction in the pipe connecting the air filter to the turbocharger compressor.
• Transmission: km may be tremors during switching and slipping. The reason is friction wear. Repair will require about 40-60 thousand rubles.
• Driving: Due to a malfunction of the stop light switch ("frogs"), the ESP icon constantly lights up, and periodically ABS.
• Body and salon: There is no hint of rust even on the first copies.
