Audi A6 C5

The next Audi A6 was introduced in 1997 and was produced until 2004. It's got a new C5 platform. Her style became the face of the entire Audi lineup. In 2000 and 2001, the Audi A6 C5 entered the top ten cars, making a worthy competitor to the leaders in its class - the BMW 5 and Mercedes E-Class. The body was designed to meet the current requirements of passive safety, which allowed to get the A6 C5 a fairly high score for safety. Four stars out of five are the scores earned in the EuroNCAP front crash test. One point was withdrawn for injuries to the driver's knees. In May 2001, the "six" was modernized. From the cars of early releases, the restyled versions differed in sized headlights and the right rear-view mirror, new rear lights and a chrome edging of the air intake in the bumper (previously such a “fan” only versions with a V8 engine). Changes also affected the suspension and line of power units. The first “charged” version of the Audi S6 II model was released in late 1999, and in 2003 there were even more powerful sedan Audi RS6 and wagon Audi RS6 Avant.

Engines

The car was equipped with both gasoline and diesel engines. Gasoline was represented by a row four volume of 1.8 liters with turbocharging (150 hp and 180 hp) and without it (125 hp), as well as V-shaped sixes 2.4 (165 hp and 170 hp) and 2.8 liters (193 hp) with 5 valves per cylinder. The most powerful power unit 2.7 liters with turbocharging developed 230 hp. In 1999, the charged Audi S6 was equipped with a 4.2 liter V8 with five valves per cylinder and 300 hp at the output. Later, with the help of two turbochargers, the power of the 4.2-liter Audi RS 6 unit was raised first to 450, and then to 480 hp. In 2001, instead of atmospheric 1.8 liters, a 2-liter 130 hp was installed, and the turbocharged 1.8 recoil 180 hp was discontinued. At the same time, the power of the 2.4-liter engine was raised to 170 hp, and 2.7 liter - up to 250 hp. To replace the 2.8 liter unit came 3 liter, developing 220 liters. with. Diesel 1.9 TDI capacity of 110 hp and 2.5 TDI 150 hp after restyling forced up to 130 and 180 hp, respectively. 2.5 liter diesel engine had also versions of 155 and 163 hp. The body line was represented by the C5 sedan and the Avant 4B wagon. The Audi A6 C5 engines are generally reliable. But, like any unit, they are not without drawbacks. The main problems are associated with high mileage and inevitable aging, as well as unjustifiably inflated prices for service in young years, which forced owners to resort to savings.

Transmission

The cars were equipped with a 5- or 6-speed manual transmission, as well as a five-speed "automatic" with a dynamic DSP program, which took into account not only the manner of control of the driver, but also the adhesion of the tires to the road. The built-in Tiptronic system allowed you to switch to manual control if necessary. In 2000, the Multitronic variator began to be used in parallel, not distinguished by high reliability. It could only be used on the front-wheel drive versions. The four-stage machine was 1.9 TDI. On the all-wheel drive version of the Quattro was installed exclusively manual transmission. Of the transmissions, the most survivable was a mechanical one, which waited until the first signs of poor transmission of at least 200,000 km. Usually the synchronizers were worn out, and with large runs - the differential. The cost of replacing the clutch will be in the region of 13 000 rubles. The automatic box is a little more capricious, and the most unreliable is the Multitronic CVT. The main reason for variator failures is the ECU, the failures of which lead to the failure of the box. The chain used instead of the belt required replacement after 100,000 km. However, sometimes the variator easily reached 200,000 km, followed by expensive repairs, extending the "life" by 40-70 thousand km. Typtronic is more durable than Multitronic. The declared resource of the automatic transmission is about 300,000 km. But in fact it is much smaller - about 150-200 thousand km. The main problems: oil pump failure and friction wear. As a rule, after 200,000 km there were jerks and tremors when switching.

Walking

The suspension of the Audi A6 2, depending on operating conditions, runs from 80 to 100 thousand km. The most expensive is the aluminum front suspension. A set of five lever pulls out for 20 000 rubles. The lower back levers are quicker.

The rear multi-link suspension (Quattro versions) is much more durable. And the back beam is almost eternal. However, when tires wear on the rear axle from the inside, the entire beam will need to be replaced.

Hub bearings and SRUS are groomed for 200,000 km.

The pump GUR will serve up to 200-300 thousand km. A little later you will need repair or replacement of the steering rack (12-15 thousand rubles).

On cars older than 99-00 years require increased attention hoses brake system. Due to a constructive flaw in the clogging of drainage in the body, water enters the vacuum brake amplifier. The new VUT will make part with 6-15 thousand rubles.

Body and salon

The design of the car, even despite its respectable age, is worthy of the most flattering reviews. No less advantages and paintwork, especially untouched accident. But with age, the arches of the wheels begin to bloom, sometimes the paint around the door hinges blows up. Foci of corrosion may appear under the sealing gum at the bottom of the doors and on the thresholds. The fifth door of the Avant wagon sometimes gets sick under glass. And clogged water drains and leaky seals contribute to the ingress of moisture under the floor covering, which contributes to the corrosion of the floor. Chrome inserts darken over time, and in molding - under the headlight - begins to climb chrome. Often the edges of the lower moldings of the doors move away due to weakening of the mounting - metal inserts that are susceptible to corrosion. With age, the standard optics go blind - reflectors burn out. The new set of headlights is available for 25-30 thousand rubles. The interior of the car has good noise insulation and very high-quality finishing materials that will not bother with their creak. The only squeaky detail is the rear double seat, which falls silent when there is a passenger. You can fix the situation by gluing plastic on the sides of the seat. Another weakness is the plastic guide glass in the doors. Most often in the driver's door due to its frequent use. The windows do not close until the end, returning down. Sometimes silicone lubrication helps, if the reason is banal souring. Electronics is the trouble of the high-age Audi A6 C5. For example, the arrows of the sensors of temperature of the coolant, fuel level and other indicators begin to live their lives or are too silent.

Engines

• The main problems are associated with high mileage and inevitable aging, as well as unjustifiably inflated prices for service in young years, which forced owners to resort to savings.
• After warming up on the singles appeared the noise of the chain camshafts (knock), subsided with an increase in revolutions of more than 1500 rpm.
• Replacement of the temporary drive is recommended every 60,000 km.
• Many problems are caused by an electric coolant temperature sensor, which often “gluts”, tending from 20 to 150 thousand km.
• It manifests itself inflated temperature readings, and problems with starting can occur.
• In the list, the loss of sealing ring nozzles in severe frost, giving itself the appearance of the smell of gasoline.
• Refused ignition coils, required replacement of the Hall sensor (camshaft position) and oil temperature sensor.
• The latter often gave a leak before his death.
• Engines with oil pump failure, which happened with a large mileage and partial oil starvation, showed miracles of reliability, having endured the "dry" to the car service, and without jamming and even turning the inserts.

• The main problems: oil pump failure and friction wear.
• However, when inspecting the all-wheel drive version of the "Quattro", special attention should be paid to the Silentblocks, the boulders of the front axle, differential and rear axle.

• And clogged water drains and leaky seals contribute to the ingress of moisture under the floor covering, which contributes to the corrosion of the floor.
• Often the edges of the lower moldings of the doors move away due to weakening of the mounting - metal inserts that are susceptible to corrosion.
• There is only one way out – a complete replacement of the dashboard.
• The poor location of the comfort unit leads to loss of control of the glass and light in the cabin.
• Often "glutch" or completely fail the end of the doors built into the locks.
• The generator (from 8000 rubles) and the starter have to be repaired or changed. And after 350-450 thousand.

Most of the Audis are imported from Europe. Officially sold in Russia is not so much. Often you can meet representatives from overseas - from the American mainland. They have a very small list of differences from their European counterpart.

Time takes its toll, and the owners of the current Audi A6 C5, one way or another, are forced to visit the service with various problems. In general, the average mileage to the first serious breakdown was at least 200-250 thousand km. There are copies that did not cause trouble to the owner, and up to 300,000 km.

When choosing and buying a used Audi A6 C5, don’t rely on the mileage counter. Almost all C5, especially imported from abroad, have a twisted mileage, and on the Internet you can inexpensively buy an adapter for controlling the odometer counter. Therefore, do not be deceived by the fact that you see a car with a small mileage and age of about 20 years.
