It was with this model that the company began to radically change the look of its cars. The new generation A6, whose production began in 1997, had a body completely devoid of any faces. I must say that not everyone liked this approach to design, but over time they got used to it, and it became a trademark for almost everyone. Audi models.
The second generation A6 was offered with two body types - a sedan and a station wagon. In addition to the usual performance, they also had sports options - S6 and RS6. A little later, a modification for bad roads appeared - Allroad, which was positioned as a separate model. In 2001, a restyling was carried out, which primarily affected the appearance. Headlights and right mirror are larger, section reversing in the lanterns it is made in the form of a circle. At the front, the updated cars have become recognizable thanks to the large false radiator grille with chrome trim.

Separately, it should be noted that the AUDI A6 sold in countries with poor road conditions, regular metal protection is installed engine compartment. When conducting body repair and the purchase of related spare parts, it should be borne in mind that the version with a 4.2 liter engine has a larger front overhang and, therefore, other body parts. Difficulties can also arise during the repair
aluminum hood, so sometimes it’s easier and cheaper to replace it than to look for a good specialist and pay for laborious work.
The body is galvanized and for many years of operation does not cause any serious complaints. Nevertheless, some little things can overshadow the life of the owner. For example, the plastic guides in the power window mechanism are destroyed, making it difficult to lift the glass. On vehicles manufactured before mid-1998, the linkage comes off the inner door handles. Periodically, the souring of the wiper trapezium occurs due to exposure to chemicals. This problem cannot be completely solved, but it is still possible to extend the service life of the assembly if it is periodically disassembled and lubricated. Another misfortune is clogging drainage holes causing water to enter the cabin. From time to time they need to be cleaned, just like the evaporator of the air conditioner - otherwise the condensate from it will pour out onto the floor of the cabin.

Over the entire period of production, the model was equipped with a large number of engines, some of which had several modifications. Most often on secondary market there are cars with gasoline engines: 1.8 (ADR, 120 hp - until 1999; AJP, 125 hp - 1998-1999); 1.8T (AEW, 150hp; A1Ts 180hp); 2.0 (ALT, 130 hp - since 2001); 2.4V6 (AGA, 165 hp - until 2001; ASM, 170 hp - from 2001); 2.7 V6 Bi-Turbo (AJK, 230 hp - 1999-2001; ARE, 250 hp - since 2001); 2.8 V6 (ASK, 193 hp); 3.0 V6 (ASN, 220 hp - since 2002); 4.2 V8 (ASG, 300 hp - since 1999, 340 hp (S6), 450 hp (RS6)). Diesel engines are less common, but there are a lot of them - this is 1.9TDI (AFN, PO hp - until 1999; AIM, 115 hp - 1999-2001; 130 hp - since 1999); 2.5TDI V6 (AFB, 150 HP - until 2001; AKE 163 and 180 HP - from 2001)

All engines in operation showed their best side. By and large, they only need strict adherence to routine maintenance. However, it was not completely without drawbacks. Poor starting of the ADR engine in wet weather was observed on cars of the first years of production. This problem is treated by re-programming the control unit. The use of low-quality oil leads to breakage of hydraulic valve compensators, as well as to coking of the turbine on the 1.8T engine and its subsequent failure. On the gasoline engines with a working volume of 1.8 liters with a run of about 100 thousand km, the rheostat fails throttle valve. On the ALT engine, the plastic elements of the crankcase ventilation system are often destroyed. In addition, with a significant mileage, the motors of this series have a very high flow oil due to wear valve stem seals. The engine oil pump is very sensitive to the quality of the oil, so do not delay its replacement.

Poor fuel quality disables the fuel level sensors on all all-wheel drive versions. Since there are several such sensors (due to the complex shape of the tank), replacing them results in a decent amount. On diesel engines 2.5 V6, leakage of shaft seals and gaskets indicates clogging of the crankcase ventilation system. On vehicles with this engine, big backlash viscous coupling of the cooling fan, the radiator may be damaged by the fan impeller. With unskilled service fuel system the injection pump fails, despite the fact that the pump is not repairable. Very rarely, the rubber damper of the crankshaft pulley is stratified, mainly with a run of 120-140 thousand km. Front engine mount wear is common to all V6s.
Routine work is quite common. For gasoline engines, changing the oil and oil filter produced every 15 thousand km, for diesel engines - every 10 thousand km. Air filter changes with a run of 40 thousand km, however, with severe air pollution, the period should be reduced to 30 thousand km. Spark plugs in gasoline engines in most cases "nurse" 40-60 thousand km. In addition to the above works, do not forget about replacing antifreeze every 60 thousand km or after 3 years. The timing system requires the least intervention. So, the belt and rollers, and at the same time the cooling system pump and the belt auxiliary units on in-line engines they change at a run of 90 thousand km, and on V-shaped engines - after 120 thousand km. When the car changes 140-160 thousand km, you should prepare to replace the valve stem seals. Of course, their life expectancy largely depends on the driving style, but, as practice shows, such a milestone is the limit for caps. Car owners with diesel engines in addition to all this, it is worth replacing the nozzles with a run of 170-200 thousand km. and check the car in the service. If the quality diesel fuel was doubtful, then this operation may have to be carried out earlier. In any case, in the presence of a large amount of impurities in the fuel, regardless of its type, it is recommended to flush the fuel tank every 2-3 years.
The transmission is either a 5- or 6-speed manual or a 5-speed Tiptronic automatic. In addition, cars with a Multitronic CVT equipped with 1 manual shift function are often found. The drive is carried out either on the front or on all wheels (quattro).

Despite the widespread belief that an oil change is not required in an AUDI A6 manual gearbox, this procedure should still be done at a mileage of 150 thousand km. km. In an automatic transmission, the oil and filter need to be changed almost twice as often - every 80 thousand km. The clutch in a transmission with a manual gearbox usually “nurses” 150-200 thousand km. Every 3-4 years, you will have to change the covers of the CV joints, with a run of 100-120 thousand km - drive seals (quattro), after 100 thousand km - hub bearings.

The main problems include the failure of the control unit automatic transmission gears due to water intrusion due to clogged drain holes. In rare cases (most often with a sporty driving style), the Tiptronic gearbox clutches are completely worn out at a range of 180-200 thousand km. The suspension is fully independent with stabilizers: front - MacPherson strut, rear - multi-link. When restyling in 2001, it was modernized. On vehicles sold in countries with poor road conditions, the suspension is strengthened, the ground clearance. Usually maintenance work include the replacement of front shock absorbers after 90-100 thousand km, rear - after 110-120 thousand km. The front suspension arms change with a run of 50-60 thousand km, rear - 60-80 thousand km (quattro) and 140-150 thousand km (for front-wheel drive versions). In order to avoid difficulties in repair work, it is recommended to periodically lubricate the fasteners, which are very prone to souring. A noticeable, but practically not affecting handling and comfort disadvantage is the knock of the upper spring pads. rear suspension on cars manufactured before 2000.

AUDI A6 is equipped with disc brake mechanisms all wheels. ABS is standard equipment. Replacing pads at the front is usually required after 30-40 thousand km, at the rear - after 50-70 thousand km, brake discs at the front - after 60-80 thousand km, at the rear - after 120-140 thousand km. brake fluid must be changed every 30 thousand km or every 2 years. In rare cases, with a run of more than 100 thousand km, the hoses of the rear brake calipers leak.

Electrical equipment is the most complex part of the model. Thus, communication between the main modules is carried out via a multiplex bus. That's why everything optional equipment can only be connected to a specialized service.
Nevertheless, this system also requires care - it is periodically recommended to clean and lubricate the contacts of the front turn signals, which are prone to oxidation, with a water-repellent composition. The connectors of the comfort unit and airbags can bend in the event of water penetrating the cabin floor due to clogged drainage holes.

We can say with confidence that the Audi A6 in the back of the C5 is not as difficult to maintain as it seems at first glance. If you are not sure what to choose a good option on your own, order a car in the selection. So the most popular spare parts can be bought in the vast majority of car dealerships. At the same time, the owner will have a choice between expensive "original" and non-original spare parts of different price levels and quality.

3.5 rating 3.50 out of 5 (2 votes)

Automobile Audi A6 (C5) this is a business class car without unnecessary external aggression. It is solid, respectable, even in the basic configuration it has a lot of equipment: separate climate control, 4 airbags, central locking, power steering, ABS, power mirrors and height-adjustable steering wheel.

Despite the fact that this car has many advantages, you can also meet negative ones. reviews about Audi A6 C5. One of the main drawbacks is the very high price. The car, even in the basic configuration, is not available to everyone. What can we say about the most equipped modification, in which there is a navigation system with a TV tuner, heating, steering wheel, power seats and position memory.

What reviews does the Audi A6 C5 have as standard

The German car of 1997 - 2004 of release for Russia was equipped with a V6 and V8 power unit:

• engine 1.8 l. - power 125 hp
• turbocharged engine 1.8 l. - power 150 hp
• turbocharged engine 1.8 liters. - power 180 hp
• motor 2 l. - power 130 hp
• motor 2.4 l. - power 165 hp

Audi A6 C5 with a 4.2-liter engine is very rare in Russia. But this modification has established itself as a car with high fuel consumption and too expensive service. The owners of Audi production until 1999 became the owner of a 1.8-liter engine with a capacity of 125 "horses". Many admit that it is a big problem in wet weather. Since it is very difficult to start it at this time. To fix this, the owners had to give the car to the service for reprogramming the control unit. Those who became the owner of a 1.8-liter engine with a capacity of 180 or 150 Horse power"lucky" no less. After about 150,000 km, the turbine fails. It has been noticed that in a 2-liter power unit, parts of the crankcase ventilation system made of plastic can be destroyed.

High oil consumption is noted in all engines of this brand. The owners claim that if the V6 engine needs about half a liter of oil per 10,000 kilometers, and the V8 engine 1 liter, then this is quite normal. Majority reviews about mechanical transmission car Audi A6 C5 positive. The 5-speed quattro automatic transmission is just as reliable. But Multitronic and Tiptronic service employees advise not to buy. Because they don't last long.

How are the brakes and suspension?

Judging by the reviews of the owners, and front wheel drive and all wheel drive vehicles reliable suspension . Depending on driving style, terrain, different elements have to be changed sooner or later. So the resource of ball bearings can be 50 thousand kilometers, or maybe 80,000 km. For change rear shock absorbers the car should depart about 110 thousand kilometers, and for the front - about 90 thousand kilometers.

Which has more advantages or disadvantages?

In the Audi A6 C5, the body is made of galvanized steel, so it is resistant to corrosion. In addition, there are several pluses in favor of this car:

• a lot of equipment;
• big choice motors;
• you can easily choose a used car due to the wide range of used cars on the market;
• high sound insulation.

Among shortcomings:

• power windows quickly fail;
• contacts in windshield wipers and turn signals are oxidized;
• high cost of spare parts and the machine itself;
• consumes a lot of oil and fuel.

According to the reviews, it is clear that the car is well equipped, but you should not buy a used car with the last funds, as you will have to invest a lot in it.

The new Audi A6 was introduced in 1997 and was produced until 2004. Audi received a new C5 platform. The new style has become the face of the entire Audi range. In 2000 and 2001, the Audi A6 II entered the top ten best cars, having made a worthy competition to the leaders in its class - BMW 5 series and Mercedes-Benz-E-Class.

The body of the Audi was designed to meet modern requirements passive safety, which allowed the new A6 C5 to get a fairly high score in crash tests. Four "stars" out of a maximum of five - the rating earned by the car in a frontal EuroNCAP crash test. One point was deducted for the driver's knee injury.

In May 2001, the "six" was upgraded. The restyled versions differ from the cars of early releases in larger headlights and a right rear-view mirror, new taillights and a chrome trim for the air intake in the bumper (previously only versions with a V8 engine flaunted this). The changes also affected the suspension and powertrain line.

The first "charged" version of the Audi S6 II model was released at the end of 1999, and in 2003 even more powerful ones appeared. Audi sedan RS6 and station wagon Audi RS6 Avant.

Engines.

The car was equipped with both gasoline and diesel engines, which proved to be quite reliable and economical. Petrol were represented by a 1.8-liter in-line four with a turbocharger (150 hp and 180 hp) and without it (125 hp), as well as 2.4 V-shaped sixes (165 hp and 170 hp) and 2.8 liters (193 hp), with 5 valves per cylinder. The most powerful power unit A 2.7-liter turbocharged developed 230 hp. In 1999, a charged Audi S6 was equipped with a 4.2-liter V8 with five valves per cylinder and 300 hp. at the exit. Later, by installing 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 a 1.8-liter engine without turbocharging, they began to install a 2-liter engine with 130 hp, and a 1.8 turbo with 180 hp. taken out of production. They also raised the power of the 2.4-liter engine to 170 hp, and the 2.7-liter engine to 250 hp. The 2.8-liter unit was replaced by a 3-liter 220 hp unit.

Diesel 1.9 TDI with 110 hp and 2.5 TDI 150 hp after restyling they boosted to 130 and 180 hp. respectively. The 2.5 liter diesel also had versions with 155 and 163 hp.

The body line was represented by the C5 sedan and the Avant 4B station wagon.

The Audi A6 C5 engines are generally quite reliable. But, like any unit, it is not without drawbacks. The main problems are related to the high mileage of cars and their inevitable aging, as well as unreasonably high prices for after-sales service.

High-quality fuel is a favorite "delicacy" German motor who prefers 95 or 98 gasoline. Units refueled by the 92nd more often than others suffer from interruptions in operation.

The chain drive resource is at least 180 thousand km, but, as experience shows, it is worth changing it after 120 thousand km. Replacing the timing belt drive is recommended every 60,000 km. At the same time, do not forget to change the pump as well - it rarely takes care of two timing replacements.

A lot of problems are caused by an electric coolant temperature sensor, which often “bugs”, nursing 20-150 thousand km. Many owners of the Audi A6 C5 have encountered its replacement. It is not expensive. It manifests itself as overestimated temperature readings, and there may be problems with starting.

After 200,000 km, most likely, it will require replacement catalytic converter, which, having worked out its resource, will begin to contribute to an increase in fuel consumption and eat up part of the engine power - due to an increase in pressure in front of it at the outlet. Just as often, he becomes guilty of "uneven" engine idling.

After 200,000 km, a number of specific diseases appear. In the list of leaks in hard frost sealing ring of injectors, manifested by the appearance of the smell of gasoline. Vacuum hoses also lose their tightness, resulting in a noticeable vibration. Ignition coils are starting to fail. Most likely? will require the replacement of the Hall sensor and the oil temperature sensor. The latter often begins to leak before his death. The resource and pillows of the engine dries up. The list of consumables may include a “water” pump and a fuel level sensor. Over time, they lose their elasticity and tan the hoses of the engine systems and power supply. They become fragile, which will require accuracy when dismantling them.

After 250,000 km, some owners are faced with the problem of starting a hot engine. As a rule, the reason for the failure of one of the links in the following chain: relay, Hall sensor, position sensor crankshaft or fuel pump.

Often, with a high mileage, it begins to “snot” from under the cylinder head cover. There can be several reasons: corny loose cover bolts (which happens very rarely), a clogged crankcase ventilation system - a valve or pipes (the main reason) or overheating of the engine, which caused the cover to deform. Clogged crankcase ventilation can be identified in a simple way. If the palm attached to open lid engine oil neck, “pushes out”, which means the system needs to be cleaned.

Oil consumption with a run exceeding 200 thousand km often begins to grow steadily and therefore requires more frequent monitoring of its level. The engines of the Audi A6 C5, in the event of an oil pump failure, which happens with high mileage and partial oil starvation, showed miracles of reliability, enduring the “dry” to a car service, without jamming or even turning the liners. The “oiler” on the instrument panel will report a decrease in pressure in the oil system.

After 200,000 km. the hydraulic chain tensioner begins to “die”. After warming up at idle, the noise of the camshaft chain (knocking) appears, subsiding with an increase in speed over 1500 rpm.

The turbocharged 1.8 and 2.7L versions will require more attention, primarily due to the turbo itself. Its resource is about 150,000 km. Next - either a repair that will extend the life of at least 20-30 thousand km, or a replacement that will make you pay 25-35 thousand rubles. for 1.8 liters and 60-70 thousand rubles. for 2.7 liters, forget about it for another 120-150 thousand km. Over time, the plastic base of the turbine overpressure valve bursts, and the crankshaft oil seal begins to leak, more often when starting a cold engine. The fuel pump, aging, will also require replacement, not allowing the engine to squeeze out the "maximum". The weak point is the sealing ring at the heat exchanger, which can burst in severe frost, making room for oil.

The 2.4-liter engine is the most massive among the Audi A6, traveling around the expanses of Russia. To the leak of the cylinder head cover, the leak of candle wells is often added, the oil in which has a far unfavorable effect on the characteristics of the candles.

2.8 liters stand out increased consumption oils. There may be an oil leak through the cover of the hydraulic chain tensioner. On models before 1998, the camshaft chain tensioner had a short resource.

A 3-liter unit with high mileage will require replacement of the intake manifold gasket.

Diesel engines, like all relatives, require more frequent maintenance and good diesel fuel. Among the weaknesses of the 1.9 TDI, one can note the corrugation connecting an exhaust manifold with silencer. 2.5 TDI until 2002 had problems with camshafts. After 220-250 thousand km, it may require replacement of the injection pump due to failure of the rotor pair. By 400,000 km, it will most likely be required overhaul with the replacement of the piston, turbine and shaft grinding.

Transmission.

The cars were equipped with a five-speed mechanical box gears or a five-speed "automatic" with a dynamic DSP program, which took into account not only the driving style of the driver, but also the grip of the tires on the road. The built-in Tiptronic system allowed, if necessary, to switch to manual control. In 2000, they began to install the Multitronic CVT, which is not very reliable. A four-speed "automatic" was installed on a 1.9-liter TDI diesel.

The all-wheel drive version of the Quattro was equipped with only a manual transmission, while the front-wheel drive models could also be ordered with a four-speed automatic transmission.

Of the gearboxes installed on the Audi A6 C5, the mechanical one turned out to be the most tenacious, caring for at least 200 thousand km until the first signs of poor gear shifting. automatic transmission more capricious, and the most unreliable - the Multitronic variator. The main reason for the failure of the ECU variator, failures in which lead to the breakdown of the box. The chain used instead of the belt needs to be replaced every 100 thousand km. Often, the variator served 200 thousand km without problems, followed by expensive repairs that extended the “life” by 40-70 thousand km.

Tiptronic is more tenacious than Multitronic. The declared resource of automatic transmission is about 300,000 km. But in reality it is much less - about 150-200 thousand km. Main problems: failure of the oil pump and wear of the clutches. As a rule, after 200,000 km jerks and shocks appear when switching. The bulkhead of the box briefly extends its life, and service specialists are sometimes unable to carry out qualified repairs, leaving the owner alone with his problem.

Chassis.

Suspension Audi A6 II, depending on the operating conditions, goes from 80 to 100 thousand km. The most expensive is a five-link aluminum front suspension, the set of which pulls out 12-15 thousand rubles. Eight lever will cost 20-25 thousand rubles. The lower rear arms give up faster. When the tires are worn rear axle from inside the entire beam will need to be replaced. Hub bearings and CV joints nursed for 200,000 km.

When examining the all-wheel drive version of the QUATRO, special attention should be paid to silent blocks, oil seals front axle, differential and rear axle. special complaints system all-wheel drive does not call.

The power steering pump nurses up to 200-300 thousand km. On machines older than 99-00, hoses require increased attention brake system. Due to a design flaw when the drainage in the body is clogged in vacuum booster brakes get water.

Body and interior.

The design of the car, even despite its considerable age, is worthy of the most flattering reviews. No less advantages and paintwork, especially not touched by an accident. But with age, the wheel arches begin to bloom in the very first representatives of the model, sometimes the paint around the door hinges swells. Corrosion pockets may appear under the sealing gum at the bottom of the doors. Chrome inserts darken over time, and on the molding - under the headlight - chrome begins to peel off. Often, the edges of the lower door moldings move away due to the loosening of fasteners - metal inserts that are susceptible to corrosion. The fifth door of Avant sometimes "gets sick" under glass. If the metal is “native”, then chips and sandblasted thresholds almost do not rust. Affects the technology of galvanizing the body used by AUDI.

The interior of the car has good sound insulation with very high quality finishing materials that will not pester with their creak. The only creaky detail is the rear double seat, which shuts up when there is a passenger. You can correct the situation by sizing the plastic on the sides under the seat. Another weak point is the plastic glass guides in the doors. Most often in the driver's door due to its frequent use. At the same time, the windows do not close completely, returning down. Sometimes silicone grease helps if the cause is banal souring.

Electronics is another weak point of the overgrown Audi A6 C5. Often the arrows of the coolant temperature sensors, fuel level and other indicators take on a life of their own or are too silent. There is only one way out - complete replacement dashboard. Morell boards from 2000-2001 are especially affected by this. In addition to a simple replacement of the dashboard, the control unit often requires a flashing. The ABS and Air Bags ECUs malfunction - often the cause is oxidation of the contacts. The unfortunate location of the comfort unit leads to loss of control of windows and light in the cabin. It is located under the driver's mat, and water gets on it. Often the door switches built into the locks are “buggy” or completely fail. The disease is treated only by replacement - the locks are not separable. Short-lived and the control relay "turn signals" and alarms - built into the "emergency gang" button.

Conclusion.

Most Audis are imported to us from Europe. There are not so many officially sold in Russia. Often you can meet representatives from overseas - from the American mainland. They have a very insignificant 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 a car service with various problems. Basically, the average mileage before the first serious breakdown is at least 200-250 thousand km. There are instances that did not cause trouble to the owner, and up to 300 thousand km.

When choosing and buying a used Audi A6 C5, pay close attention to the mileage of the car. Almost all, especially those imported from abroad, have twisted mileage, and you can buy an adapter for controlling the odometer counter inexpensively on the Internet. Therefore, you should not flatter yourself when you see a car with a mileage of 120-140 thousand km and an age of more than 10 years.

(!LANG:AUDI A6 in C5 body

SHELLAUTOEXPRESS tells today about our most popular audi car A6 in the back of C5 and about the experience of its operation in Russia

The Audi A6 Allroad quattro belongs to the second Audi generation A, the production of which was launched in 1997. The cars of this generation were equipped with a 4B body, and the platform was designated as C5. Among the cars of the second generation, there were such body options as a station wagon (called Avant) and a sedan. Based on the station wagon body, the Audi A6 Allroad quattro model was developed.

The new car was made in a style that can rightfully be called the "face of the company" for all subsequent Audi models. The body design was liked by a large number of motorists. It is understandable, because the skill of execution appearance car does not let it become obsolete even by today's standards. In addition to traditional options, a sports version of the Audi RS6 was also released with a 4.2-liter engine. But that's not all - the Audi RS6 was also put on sale with the same engine, but plus 2 turbochargers that developed 450 hp. And another version of this sports car assumed the presence of even more powerful 480 hp turbochargers. To the pluses Audi bodies RS6 can be attributed to the presence of a zinc coating and, as a result, the manufacturer's guarantee for full protection against through corrosion for a period of 10 years. The body structure is made of steel parts, and the hood is made of aluminum alloy on all cars of this brand. The Tiptronic gearbox has 5 sequential ranges. Optionally, the possibility of control through the gearshift keys is provided. Front wheel drive vehicles manufactured after 1999 may have a CVT gearbox.

In order to secure the ride, the strength of the cabin section has been reinforced. Inside there are airbags for the driver and the person who rides on front seat. Some models are equipped with airbags for persons in the rear. There are also "curtains" - pillows to prevent side impacts on the head in the event of an accident. But that's not all - special mechanisms are built into the interior of the Audi A6 to create the required tension of seat belts on all seats.

In general, the performance of the Audi A6 allows us to confidently say that German quality still remains high, but only under the condition of timely maintenance this car. If the owner treats his “iron horse” carelessly, then a lot of troubles and considerable repair costs will naturally await him. Moreover, these costs can exceed those for cars made in Japan.

Unfortunately, no matter how well the car is assembled, the owners of the modern Audi A6 C5 still have to go to car repair shops. As for statistics, it converges to a mileage of 220-250 thousand km before the first breakdown occurs, requiring serious repairs. However, there are “lucky ones” who can drive 300,000 km without any problems. The paint is also not eternal, over time, coating defects appear in the area of ​​\u200b\u200bwheel arches, swelling is observed near the hinges on the doors. It is also impossible to fully insure against surface corrosion - it is often observed under the sealing rubber at the bottom of the doors. Under the headlights, the chrome coating begins to fall off, and the rest of the chrome elements also acquire a dark shade. The edges of the moldings on the doors over time are torn away from the surface due to the loss of fastening strength of the inserts. The latter are made of metal and begin to rust. But the chips on the cases from the manufacturer are practically not susceptible to corrosion, since in this case the zinc coating provides protection.

The car interior is characterized by an excellent ability to suppress noise. The interior trim is made only from high-quality materials, so they definitely will not creak. Squeaking problems can be observed on back seat, but if a passenger sits on it, it will immediately “calm down”. Although avoiding this unpleasant phenomenon is quite simple - just glue the plastic at the bottom of the seat. The door glass guides are also vulnerable, because they are made of plastic. Glass over time stop closing all the way. Basically, this problem is observed in the door located near the driver's seat. The reason for the breakdown is the frequent opening and closing of the glass. To restore normal work, you can use a special lubricant. But only if the cause is simple souring.

Audi A6 C5 engines are distinguished by their reliability. But it was not without its downsides. The key problems are those that directly depend on the mileage. If it is too big, then troubles will definitely make themselves felt. Just as often, drivers are in no hurry to produce the necessary Maintenance your car because of the considerable prices. In the end, this results in even greater costs.

It should not be forgotten that Audi engines they like to "pamper" themselves with exceptionally "delicious" high-quality fuel - 95th or 98th gasoline. The chain drive can work without interruption all 180-200 km, but the experience of experienced drivers shows that it is better to replace it after 120,000 km. And if the valve timing drive is installed on the Audi, then the replacement should be carried out more often - after the next “wound” 60,000 km of run.

If the mileage becomes more than 200 thousand kilometers, then the following unpleasant things often occur. If the temperature is below zero, then the sealing rings that the nozzles are equipped with may begin to lose their tightness and the smell of gasoline can be felt in the cabin. It is also possible to lose tightness in the vacuum hoses, as a result of which the car begins to vibrate while driving. Ignition coils do not work well, in 90% of cases the Hall sensor will also have to be replaced. The sensor that shows the temperature may leak engine oil. If this happens, then the sensor must be replaced immediately. Engine cushions after 200 thousand kilometers also fully develop their resource. It does not hurt to diagnose the gasoline level sensor, it can also begin to become unusable. Rubber hoses in the engine and related to power from time to time begin to harden and lose elasticity. Care must be taken when replacing hoses due to their fragility.

And in the case of a run of more than 250 thousand km, it is difficult to start even a warm engine. A malfunction that occurs in a circuit of elements of this type is to blame here: a gasoline pump, a Hall sensor and a relay. Often the head cover mounted on the cylinder blocks begins to leak. Here, too, there may be a number of reasons: the bolts begin to hold the cover badly (the probability of this is very small), or (which happens much more often) the ventilation system for the crankcase exhaust is clogged - these are either pipes or a valve. Sometimes severe overheating Audi motor can lead to deformation of the cover.

An obvious consequence of high mileage (more than 200 thousand km) is a noticeable increase in engine oil consumption. In 90% of cases, this consumption does not exceed the norm set by the manufacturer, but requires more careful and frequent monitoring. If the pressure in the oil supply system decreases, which also often happens after a significant mileage, then the corresponding indicator on the dashboard will always inform the driver about this.

Unexpectedly, the miracles of strength were demonstrated by a manual gearbox installed on the Audi A6 C5. The first symptoms of poor performance in most cars are observed only after 200-220 thousand kilometers. But the most unreliable node is the Multitronic variator due to a rather faulty ECU. If the belt is replaced with a chain, then even it will have to be changed every 80-100 thousand kilometers. One way or another, the variator will have to be repaired, but the repair is enough for no more than another 50 thousand kilometers on average.

The automatic transmission has a longer service life than the Multitronic. And although the manufacturer claims that nothing will happen to this device until 300,000 km, sad practical experience shows that the automatic transmission flies after 150,000 km. Among the main causes of failure should be attributed the wear of the friction clutches and the failure of the oil pump. The symptoms of the automatic transmission running out of its resource are as follows: there are jerks and jerks of the car when changing gears. Automatic transmission repair is practically impossible, even in service centers. And if it is somehow put in order, then in any case it will not be for long.

K is typical weak points long-traveled Audi also applies to electronics. Often the readings of the instruments do not correspond to the real state of affairs. And if this happens, then you need to change the entire dashboard to a new one. The most vulnerable in this respect are the Morellian dashboards released in 2000. But the matter is not limited to just one replacement of the dashboard, it is often necessary to reflash the entire control unit.

The period of trouble-free operation of the suspension of the Audi A6 II is usually 85-100 thousand kilometers. Among the most expensive options includes a 5-arm aluminum suspension.

A set of these levers, if replaced, will cost about 25,000 rubles. But the wear on the rear lower arms comes even faster, and this should also be borne in mind. If you have a QUATRO version, then traditionally vulnerabilities this modification includes front axle seals and drive silent blocks made of rubber. As for the drive system, it is quite reliable.

SHELLAUTOEXPRESS is waiting for the owners of these vehicles to pass scheduled maintenance, as well as in connection with the problems encountered during operation.
