Audi A4 B6/8E

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. When running 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 variable variable variable variable variable variable variable variable variable variable variable variable variable variable control program DPR.

"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). The original costs about 10 thousand rubles, non-original - 4-4.5 thousand rubles.

Walking

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 little expensive repairs 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, with the engine fully warmed up, warm air will cease to be supplied to the cabin.

Electrician.

Due to a break in 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 the car keys due to oxidation of contacts on the comfort unit or failure of the unit processor.

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.
