Is a6 c5 relevant at the moment. Buying a used Audi A6 (C5): which engine should you prefer and should you be afraid of the Quattro? Body and electrical equipment

This catalog contains optics for 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004 models.

The Audi A6 is a stylish and elegant car that seems to need no improvement at all. But AUDI owners are well aware that this model can and even should be improved. First of all, it concerns optics.

If you are thinking about tuning the Audi A6, you cannot do without replacing the optics. And in our store you can buy tuning optics for this exquisite and powerful car.

First of all, we want to draw your attention to the headlights for the corrector. Safety on the road must be ensured by all road users, and this is impossible if the driver of an oncoming car is blinded by the headlights of your car - on a rough road, with ups and downs. The corrector will help solve this problem.

Also, we would like to draw your attention to linzovannaya xenon headlights with a luminous rim - the so-called "angel eyes". In terms of practicality, this may not be the most necessary addition, but such headlights look very impressive.

In our store you can also buy headlights with LEDs. Pure light, powerful luminous flux, durability and low energy consumption - all these are the undoubted advantages of LED headlights. In addition, these headlights look very impressive.

In 1997, spring came and Audi released a new body for the Audi A6 C5, they were already sold in sedan and station wagon (Avant). In the new version, of course, they changed the design, but the silhouette and style of the “muzzle” of the car itself remained similar to all other Audi models, for example,. The design was redesigned in such a way that the aerodynamics of the car improved and, as a result, the model became a serious competitor for the Mercedes-Benz E and BMW 5. A few years later, one of the car magazines included this sedan in the list of 10 best cars in 2000.

Starting with this model, its famous sports version appeared, which was called.

Regarding the body, the company decided to do everything ideally and galvanized it, so that it did not rust, the manufacturer, knowing this very well, gave the buyer a 10-year warranty on the body.

Exterior


In front, the sedan received large optics with a lens inside, but in general with a halogen filling. There is a long hood with fairly strong reliefs the width of the grille. The radiator grille, in turn, has a chrome trim around. The massive bumper of the model also has a chrome trim in some places, as well as round fog lights.

The side of the car has really muscular fender flares and a slight aerodynamic line at the top. The shape of the body has also changed, it has become smoother.


The rear part also has a smooth shape, optics of a different shape with a good design are used. The smooth large trunk lid essentially has nothing interesting except for the chrome insert at the bottom. The rear bumper has a huge plastic insert and, in fact, nothing more.

Dimensions:

  • length - 4.796 m;
  • width - 1.810 m;
  • height - 1.453 m;
  • wheelbase - 2.760 m;
  • clearance - 0.120 m.

The suspension of the car is completely made of aluminum, which slightly reduces reliability, but reduces the weight of the car. The model has a completely independent system, a multi-link system is installed in front, it is a stabilizer bar and 4 levers for each wheel. A multi-link system is also used at the back.

The manufacturer offered different gearboxes for the Audi A6 C5 (1997-2004), there are both mechanics with 5 or 6 steps, and a 5-speed automatic, and there were also CVTs on some versions. The car has front-wheel drive in most trim levels, but there were also quattro all-wheel drive versions.

Salon


Unfortunately, the interior of the car has not changed much, but still there are some differences. In front there are good leather seats with heating and a little lateral support. The back row received a sofa for three passengers. In the middle below are retractable coasters. There is also an armrest with niches for small items. There is enough space both in front and behind.

The steering column is a 4-spoke steering wheel with height and reach adjustment. Dashboard - 4 small analog gauges and two large speedometers and tachometers. There is also an on-board computer with some information about the car.


The center console at the top has an alarm button and one cup holder that slides out at the touch of a button. Below is a head unit working on cassettes, these radio tape recorders have long been replaced by more modern ones. The control unit for 2-zone climate control has seat heating knobs, three monitors and many buttons for settings.

The tunnel is essentially simple, but most of it is made of wood. There is a niche for small things, a large gearbox selector. Further, the tree ends and the plastic begins, on which the selector for adjusting the rear-view mirrors is located. In the same area, there is a parking brake handbrake and an armrest. The trunk has not changed much, its volume is 551 liters.

Price


This car can be easily purchased in the secondary market, where the average price is 300 000 rubles, there are more expensive options, there are cheaper ones, as you understand, it all depends on the condition and configuration.

Buy this model or not, it's up to you. In principle, the Audi A6 C5 is a good sedan, but it is already a bit old and despite the fact that it is reliable, it still starts to break down a little bit due to age.

Video

Audi A6 C5, the model of the second generation of the "six" on the new platform, appeared in the spring of 1997. The car was produced in the body of Avant station wagon and four-door sedan. Subsequently, on the basis of the C5 platform, the Audi A6 Allroad was developed.

High competitiveness of the machine

The new style of the Audi A6 C5 has become a "signature" for the entire range of "Audi". The body of the 4B does not seem outdated, and today its design is still attractive. The Audi A6 C5 competes successfully in the market with models such as the Mercedes-Benz E-Class and BMW 5-Series. The level of car sales is consistently high. In 2001, the Audi A6 C5 was named one of the top 10 "Car of the Year" by Car & Driver magazine.

Body

The body of the machine is a steel supporting structure, fully galvanized, which allows the manufacturer to guarantee the absence of corrosion for 10 years. The hood of the car is made of high-quality aluminum alloy, and for all modifications of "Audi" without exception, regardless of the size of the engine compartment.

Power point

Audi A6 C5 engines are widely available in both petrol and diesel ranges. The line includes four-cylinder engines, in-line, with a volume of 1.8 and 2.0 cc, V-shaped eight-cylinder, 4.2 cc, V-shaped six-cylinder, with a volume of 2.4 and 2.7. These engines operate in "biturbo" mode. All gasoline engines are equipped with electronic injection and ignition of the Motronic system. The most popular is the Audi A6 C5 2 5 TDI engine, which is available in four power ratings: 150, 155, 163 and 190 hp.

Transmission

Second-generation Audi A6 cars are equipped with sequential shift gearboxes. For the first time, a five-band Tiptronic gearbox was used. Optionally available key switch speeds in the manual version. Since 1999, front-wheel drive modifications have been equipped with a CVT transmission operating in DPR mode - dynamic software regulation. From mechanical gearboxes, 5 or 6-speed were used.

For the Audi A6 C5 model, automatic transmission is the norm; automatic transmissions are installed on most mass-produced cars. In small batches, specimens with mechanical gearboxes roll off the assembly line.

Drive scheme

The Audi C5 was produced in a Quattro all-wheel drive version, with a Torsen center differential, with a uniform distribution of torque, 50 to 50 percent, between the front and rear axles. At the moment of slipping, the ratio of loads changed, depending on the situation. Torsen is quite reliable and stable, while many similar electronic-based devices often fail and do not block the center differential in time.

However, for the Torsen system, the presence of wheels of different diameters on a car is unacceptable. The machine works according to its parameters, and any design changes that it "can't understand" lead to a breakdown of the differential.

Chassis

The second-generation Audi car, created on the C5 platform, differs from its predecessors, the Audi A4 and Audi A8, in more advanced front suspension arms made of composite aluminum alloy, which are much lighter than forged or stamped steel.

The gas-filled shock absorber struts are also modernized and reinforced with coil springs. The anti-roll bar is not directly connected to the link block, but interacts with it through an intermediate connecting rod.

The rear suspension is semi-independent, multi-link, also with a stabilizer bar, but directly connected to the pendulum levers. The smooth running of the machine is provided by coil springs with hydraulic shock absorbers.

Individual Audi A6 C5 cars were experimentally equipped with pneumatic suspension, with automatic ride height adjustment, similar to the Audi A6 Allroad quattro.

Steering

The rotary mechanism of a rack-and-pinion car, with programmatic amplification of the action, depending on the speed of the car. At high speeds, the steering mechanism becomes stiffer, as it were, "dumb" so that the driver better feels the effort required to maneuver or turn.

The steering column is adjustable for tilt and height and is safety. All changes in the position of the steering rack are carried out by an electric servo with memory for the last three positions. In addition, the steering column is electronically linked to several ignition key configurations. If one key is lost, the car owner can use a spare one without fear that the lost key can be used by intruders, since the automation rebuilds the ignition lock to a new key, and it destroys the previous settings.

Brake system

The force of hydraulic dual-circuit drives is distributed diagonally. The brake mechanisms of the Audi A6 C5 model consist of front ventilated discs and non-perforated rear ones. Calipers on all wheels of a dual design with automatic return of the pistons to their original position due to vacuum vacuum.

A pressure regulator in the brake system is installed on the rear axle beam, which cuts off part of the hydraulic action if the machine is not fully loaded. An empty trunk and the absence of passengers in the back seat become the reason for closing the valve. The rear brakes in this case begin to work with less intensity.

Audi A6 C5 specifications

The main parameters of the car are designed in accordance with the best world standards. The layout is front-wheel drive or all-wheel drive, front-engine.

Dimensional and weight data:

  • vehicle length - 4795 mm;
  • height - 1484 mm;
  • width - 1983 mm;
  • wheelbase - 2760 mm;
  • curb weight - 1765 kg;

The characteristics of the machine are reflected in its positive aerodynamics and relatively low weight, which makes it possible to achieve a reduction in fuel consumption and a significant improvement in speed performance.

The car is also characterized by numerous options focused on the convenience of the driver and passengers. The cabin has a special information system that notifies the driver about the current fuel consumption, the number of kilometers that the car can travel on the remaining fuel. The computer display reflects the travel time, the temperature outside, a special weather option warns of an impending thunderstorm, heavy rain, and other manifestations of the elements.

Safety

The basic equipment of the car consists of a number of accessories and devices. Passive and active safety is provided by ten emergency airbags located around the entire perimeter of the cabin, an ASR traction control system that stabilizes movement at high speeds - ESP. The engine compartment is equipped with an anti-accident underframe, which prevents the engine from entering the passenger compartment at the time of a frontal collision.

Interior

The interior space of the car is equipped with the expectation of maximum comfort for both the driver and passengers. Air conditioning operating in Klimatronic mode, which allows air purification with simultaneous cooling, adjustable heating of all seats, electric heating of exterior rear-view mirrors and windshield washer jets.

The cabin is equipped with a two-channel audio system Symphony and Concert, with a cassette player and a DVD player. Eight quad speakers with a subwoofer provide the perfect sound. Disk feeding is automatic, by means of a changer. All vehicle configurations, including the basic standard, provide for the presence of a TV in the cabin.

The navigation system is constantly on in the car, its data is displayed on a large liquid crystal display installed in the upper part of the center console.

The car is equipped with an effective anti-theft alarm system with sensors placed throughout the cabin that monitor the movement of unfamiliar persons inside the car.

Customer opinion

The Audi A6 C5 model, reviews of which from the very beginning of serial production were only positive, is still in demand today. The opinion of buyers is unanimous - a high-class car, reliable and comfortable.

The next Audi A6 was introduced in 1997 and was produced until 2004. She received a new C5 platform. Her style has become the face of the entire Audi lineup. In 2000 and 2001, the Audi A6 C5 entered the top ten cars, competing with the leaders in its class - BMW 5 and Mercedes E-class.

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

In May 2001, the "six" was upgraded. The restyled versions differed 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 Audi RS6 sedan and Audi RS6 Avant station wagon appeared.

Engines

The car was equipped with both petrol and diesel engines. 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 2.7-liter turbocharged power unit 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, 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 an atmospheric 1.8 liter, they began to install a 2-liter with a capacity of 130 hp, and a 1.8 turbo with a return of 180 hp. taken out of production. At the same time, the power of the 2.4-liter engine was raised to 170 hp, and the 2.7-liter engine to 250 hp. The 2.8-liter unit was replaced by a 3-liter one, developing 220 hp.

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 associated with high mileage and inevitable aging, as well as unreasonably high prices for service maintenance in young years, which forced owners to resort to savings.

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

The chain drive resource is at least 180,000 km, but sometimes the chain had to be changed even after 120,000 km. After 200,000 km, the chain tensioner began to “die”. After warming up at idle, the noise of the camshaft chain (knocking) appeared, subsiding with an increase in speed over 1500 rpm.

A lot of problems are caused by an electric coolant temperature sensor, which often “bugs”, nursing from 20 to 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, the catalytic converter required replacement, which, having worked out its resource, began to contribute to an increase in fuel consumption and ate part of the engine power (due to an increase in pressure in front of it). Just as often, he became guilty of "uneven" engine idling.

After 200,000 km, a number of specific diseases appeared. The list includes the loss of tightness of the sealing ring of injectors in severe frost, posing as the appearance of the smell of gasoline. Lost tightness and vacuum hoses - as a result, a noticeable vibration appeared. The ignition coils failed, the Hall sensor (camshaft position) and the oil temperature sensor were required to be replaced. The latter often leaked before his death.

Soon the resource of engine pillows dried up. It was worth monitoring the condition of the viscous coupling of the cooling system fan (from 1500 rubles).

The list of consumables could include a “water” pump and a fuel level sensor. Over time, the hoses of the engine systems and power supply lost their elasticity and dubles. They became fragile, which required accuracy when dismantling them.

After 250,000 km, some owners encountered the problem of starting a hot engine. As a rule, the reason is the failure of one of the links in the following chain: a relay, a Hall sensor, a crankshaft position sensor or a gasoline pump (5-6 thousand rubles).

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

Oil consumption at a run exceeding 200,000 km often begins to grow steadily and therefore requires more frequent monitoring of its level. And the overhaul of gasoline engines (over 100,000 rubles) is almost inevitable after 400-500 thousand km due to exorbitant oil consumption.

Audi A6 C5 engines, in the event of an oil pump failure, which happened with high mileage and partial oil starvation, showed miracles of reliability, enduring a “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.

The turbocharged 1.8 and 2.7L versions will require extra attention, primarily due to the turbo itself. Its resource is about 150,000 km. Next - either a repair that will extend its life by 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.

2-liter aspirated return 131 hp often suffered from increased oil consumption even in the early stages of production.

The 2.4-liter engine is the most massive among the Audi A6, traveling around the expanses of Russia. Among the common malfunctions, one can single out the current valve cover, and the ingress of oil into the candle wells, which far adversely affects the performance of the spark plugs.

2.8 liters are allocated by increased oil consumption. There may be an oil leak through the cover of the hydraulic chain tensioner. On models older than 1998, the camshaft chain tensioner had a short resource.

A 3-liter unit with high mileage will require replacement of the intake manifold gasket. In addition, the BBJ version received an aluminum block with a coating on the cylinders, which crumbles with age. The ASN version sometimes upsets the appearance of cracks on the sleeves.

Diesel engines, like all relatives, require more frequent maintenance and good diesel fuel.

The 1.9 TDI is not as dynamic, but economical and rarely breaks down. Until 2001, he had direct injection and a distribution pump, and later received pump injectors. Among the weak points, one can note the air flow meter and the corrugation connecting the exhaust manifold to the muffler.

After 200-250 thousand km, it is necessary to update the injector nozzles. Pump nozzles reach 400-450 thousand km.

2.5 TDI is much more expensive to maintain. For example, to replace the timing belt, it is necessary to disassemble the entire "muzzle" (25-27 thousand rubles). Until 2002, he had problems with camshafts, rocker arms and valve guides. As a result, the engine began to make noise, vibrate and lose power.

After 220-250 thousand km, it may require replacement of the high-pressure fuel pump (the rotor pair wears out, or the control transistor of the metering valve burns out). The engine was troubled and oil leaks.

After 400,000 km, most likely, a major overhaul of the TDI V6 will be required with the replacement of the piston, turbine and shaft grinding.

Transmission

The cars were equipped with a 5 or 6-speed manual gearbox, as well as 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 use the Multitronic variator in parallel, which is not very reliable. It could only get front-wheel drive versions.

The four-speed "automatic" relied on 1.9 TDI.

The all-wheel drive version of the Quattro was equipped exclusively with a manual transmission.

Of the gearboxes installed on the Audi A6 C5, the mechanical one turned out to be the most tenacious, caring for at least 200,000 km until the first signs of poor gear shifting. Synchronizers usually wore out, and with high mileage, the differential. The cost of replacing the clutch will be around 13,000 rubles.

The automatic transmission is a little more capricious, and the most unreliable is the Multitronic CVT. The main cause of variator failures is the ECU, the failures of which lead to the breakdown of the box. The chain used instead of the belt required replacement after 100,000 km. However, sometimes the variator without problems reached up to 200,000 km, 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 appeared when switching. You will have to pay at least 100,000 rubles for the bulkhead of the box. A contract node (i.e., used with a symbolic guarantee) will cost 40-60 thousand rubles.

The all-wheel drive system does not cause any particular complaints. However, when examining the all-wheel drive version of the Quattro, special attention should be paid to the silent blocks, front axle seals, differential and rear axle. The gearbox may buzz after 300-400 thousand km (bearings). Soon it is the turn of the rear drive shafts and the cardan shaft (the crosses and the outboard bearing wear out).

Chassis

Suspension Audi A6 2, depending on the operating conditions, runs from 80 to 100 thousand km. The most expensive is the aluminum front suspension. A set of five lever pulls out 20,000 rubles. The lower rear arms give up faster.

The rear multi-link suspension (Quattro versions) is much more enduring. And the rear beam is almost eternal. However, if the tires on the rear axle on the inside are worn out, the entire beam will need to be replaced.

Hub bearings and CV joints nursed for 200,000 km.

The power steering pump will last up to 200-300 thousand km. A little later, you will need to repair or replace the steering rack (12-15 thousand rubles).

On machines older than 99-00, brake hoses require increased attention. Due to a design flaw, when the drainage in the body is clogged, water enters the vacuum brake booster. The new VUT will force you to part with 6-15 thousand rubles.

Body and interior

The design of the car, even despite its considerable age, is worthy of the most flattering reviews. The paintwork, especially untouched by an accident, has no less advantages. But with age, the wheel arches begin to bloom, sometimes the paint around the door hinges swells. Corrosion pockets can appear under the sealing gum at the bottom of the doors and on the thresholds. The fifth door of the Avant station wagon sometimes “gets sick” under glass. And clogged drains and leaky seals contribute to the ingress of moisture under the floor covering, which contributes to floor corrosion.

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.

With age, regular optics go blind - reflectors burn out. A new set of headlights is available for 25-30 thousand rubles.

The car interior has good sound insulation and 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 fix the situation by sizing the plastic on the sides of 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 the trouble of the overage Audi A6 C5. For example, the arrows of 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 - a complete replacement of the 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.

With age, the dashboard display surrenders. On the Chinese Internet site, an analogue can be purchased for only 500 rubles.

The ABS ECU and Air Bags malfunction - often the cause is oxidation of the contacts and tired soldering of the unit.

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 control relay "turn signals" and alarms - built into the "emergency gang" button.

After 300-400 thousand km, you have to repair or change the generator (from 8,000 rubles) and starter. And after 350-450 thousand km, the clogged heater radiator loses its effectiveness (4-14 thousand rubles).

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 was at least 200-250 thousand km. There are instances that did not cause trouble to the owner, and up to 300,000 km.

When choosing and buying a used Audi A6 C5, do not rely on the odometer. Almost all C5s, especially those imported from abroad, have twisted mileage, and an adapter for controlling the odometer counter can be inexpensively purchased on the Internet. Therefore, you should not flatter yourself when you see a car with low mileage and an age of about 20 years.

The model of which is still pleased with its diversity, power and reliability, today is quite in demand in the secondary market. After all, a fully galvanized body is quite durable, as are power units. The Audi A6 in the C5 body was produced from 1997 to 2004, both in the sedan and station wagon body. Of course there was also an off-road version of the Audi A6 allroad quattro.

A large set of gasoline and diesel engines of various sizes and capacities allows even today in the secondary market to choose a used A6 for every taste. In addition to front-wheel drive, there are versions with quattro all-wheel drive. 5 and 6-speed mechanical units acted as gearboxes. In addition to the 4-band automatic, stepless variator, the latest 5-speed Tiptronic automatic transmission appeared on this model.

What engines are Audi a6 c5 today can be found on our roads? The question is quite interesting, because some options were offered for a European buyer, and others for an American one. But in our secondary market you can find almost any engine options. Which Audi a6 engines exist are given in the form of a list below.

  • 4-cylinder 1.8 turbo with 150 or 180 hp (210 Nm)
  • 4-cylinder 2.0 with 130 hp (195 Nm)
  • V6 2.4 with 165 hp (170 hp) (230 Nm)
  • V6 2.7 biturbo with 230 hp (US 254 hp) (310 Nm)
  • V6 2.7 biturbo with 250 hp (350 Nm)
  • V6 2.8 with 193 hp (US 201 hp) (280 Nm)
  • V6 3.0 with 220 hp (300 Nm)
  • V8 4.2 with 300 hp (400 Nm)
  • 4-cylinder 1.9 TDI with 110 or 130 hp (285 Nm)
  • V6 2.5 TDI with 150, 155, 163 or 180 hp (370 Nm)

I would like to tell you a little more about Audi a6 c5 engine 2.4 The 2.4-liter atmospheric gasoline engine produces 165 horsepower with a torque of 230 Nm. It is a 6-cylinder V-engine with a cast iron cylinder block and two aluminum cylinder heads. A feature of the Audi a6 c5 engine 2.4 can be considered the presence of 5 valves per cylinder. That is, there are 30 valves per 6 cylinders. A photo of this technological miracle is attached.

The timing of this motor also has an interesting design. The 2.4 liter Audi a6 c5 engine has 4 camshafts, two for each cylinder head. Between themselves, the camshafts are connected by a small chain with a tensioner, as in the photo below.

But only one end of the camshaft sticks out of the two cylinder heads. That's it for them and put on the pulley for the timing belt. The two timing pulleys rotate synchronously with the crankshaft pulley by means of rollers. The timing diagram of this motor is in the image below.

It is worth noting that the more powerful and voluminous 2.8 liter V6 Audi a6 c5 has exactly the same design. The difference is only in the size of the cylinders. Some handy car owners buy a 2.8 liter Audi block with a native connecting rod and piston group at the next disassembly and rearrange the cylinder heads and everything attached from a 2.4 liter engine. At the exit, after such an upgrade, a more powerful car appears.

Another popular engine audi a6 c5 2.5 tdi which I would like to discuss in more detail. Due to the different turbine performance, the power of the 6-cylinder V-shaped turbodiesel varies from 150 to 180 hp. With a high mileage, the engine begins to rather immodestly devour your money. Firstly, the poor design of the camshafts (of which there are 4) leads to their rapid wear, which can immediately knock down any budget. Seasoned Audi enthusiasts are looking for a new type of cylinder head released after 2002, there is a different, more advanced design of camshafts with reduced friction, which increases their service life and reduces overall engine noise.

The second trouble with the 2.5 TDI diesel is variable geometry turbines, which are also expensive and often break down. Another disease is a failing electronic injection pump unit. Constantly “snotty” pallets for this motor are also a problem that arises from the crankcase ventilation filter and old-style gaskets. The filter becomes clogged and excessive pressure of crankcase gases is created, leading to the extrusion of oil from the pans. On later versions of the Audi a6 c5 2.5 tdi, this is not the case.

If you are faced with a choice - petrol or diesel used Audi A6. It must be understood that the gasoline version is more voracious, but it will require less money for repairs and maintenance than a diesel engine that is economical in fuel consumption. It is worth noting that many audi a6 c6 engines the third generation migrated from the C5 body, after a slight upgrade.
