Which motor is better for the Audi A6 C5. Audi A6 (C5): specifications and reviews

The second generation of the popular German car with its appearance on the market made the model even more in demand among buyers, and also brought the brand's sales to a new level. The arsenal of such a car included new transmissions and motors.

The Audi A6 C5 first appeared before the public in 1997 at the prestigious Geneva Motor Show. Then a four-door modification was shown. The station wagon (Avant) debuted a year later, in February, and before this world were shown photos and videos of new items.

On the assembly line of the Audi A6 C5 in the back of a sedan got up in the summer of 1997. Station wagon - in 1998. The model was discontinued in 2004, while in 2001 it was restyled.

In general, it should be noted that the second generation of this car personified the appearance of Audi's own corporate style. Therefore, the design similarities between the TT roadster and the Audi A6 C5 are not accidental. Indeed, for its time the car looked very presentable.

However, if we delve deeper into the chassis, then the innovations here are not revolutionary:

• MacPherson strut front suspension scheme;
• Rear - "multi-link".

The thrust of some power units was realized through the proprietary Quattro all-wheel drive system, and the key type of drive was front.

The Audi A6 Allroad deserves a separate discussion. This car appeared in 2000 and, in fact, became the founder of a whole class of off-road wagons.

External differences Olroad from the usual station wagon - unpainted body kit, high ground clearance, roof rails. In terms of technology, it is noteworthy that all-wheel drive was already available in the basic equipment.

Another interesting modification of the Audi A6 C5, which was positioned as a factory tuning, is the S-line. Such a car can be recognized by a special sports suspension with low ground clearance, aerodynamic body kit, massive bumpers, S-line letters, sports paraphernalia of the interior (sports seats, steering wheel, aluminum pedals).

Motors

The petrol range is represented by 1.8-4.2 liter engines. Power ranges from 125 to 300 horsepower. Diesel engines have a volume of 1.9-2.5 liters, the potential of which ranges from 110 to 180 horsepower. A choice of a five-six-speed manual transmission, a five-six-speed automatic transmission, a variator.

It was with these engines that a new era began for their maintenance, for example, in order to replace the timing belt, you will have to disassemble the whole face.

And other types of work (replacing the air conditioner compressor, thermostat, cooling pump) require removing the front bumper and moving the muzzle to the service position.

Price policy

In the secondary market, the Audi A6 C5 can be found with two body types:

What do users think?

Feedback from the owners suggests that the Audi A6 C5 is an excellent representative of the E segment. This is confirmed, first of all, by the large size of Audi - it is spacious inside. Also, in favor of comfort, many attribute a soft suspension.

As for the motors, they are very popular, but there are claims to them in terms of reliability, as well as oil consumption per 1000 kilometers. Looking through the reviews, you can often read about the unreliable timing drive and clutch, as well as the short life of the turbine.

Overview

Appearance

Audi A6 C5 looks respectable and attractive. It is worth highlighting the correct and strict proportions of the body, its unobtrusive contours, a large radiator grille with an equally noticeable brand emblem, a rectangular configuration of head optics and a stylish aerodynamic body kit.

The front bumper contains volumetric sections that effectively cool the engine compartment, also contributing to a decrease in aerodynamic coefficient.

Salon

It is quite spacious and cozy inside. Solid materials are combined with competent assembly, and the calm color scheme hardly contrasts with the seasoned architecture of the front panel.

The center console is compact and thoughtful at the same time. Despite the fact that the control keys of the media system and the air conditioning unit are close to each other, it is not difficult to understand their purpose due to the large size and font.

The same can be said about the instrument panel - large digitization and the type of the on-board computer do not force you to be distracted from the road to read the readings.

The front seats are comfortable for a long journey due to the optimal rigidity and well-thought-out profile, but the side support rollers are widely spaced and almost not pronounced.

As for the rear sofa, it can not only please passengers with spaciousness, but also with functionality - a small organizer is organized in the central armrest, which allows you to put small things there.

The trunk of a sedan by the standards of its segment is simply huge - 551 liters of usable volume. The luggage compartment of the station wagon is more modest - 455 liters, but it can be increased to 1590 liters if the rear backs of the sofa are folded down.

Driving performance

Specifications Audi A6 C5:

• Turbocharged 1.8 liter engine. Power is equal to 150 horsepower. It is this power plant that is in high demand among the consumer.
• Five-band automatic transmission.
• Front-wheel drive.

The engine has a pronounced turbo pit up to 2000 thousand rpm and refuses to clearly accelerate from a standstill. However, at medium revs, a noticeable pickup appears, and the car is transformed - the gas pedal becomes sensitive to pressure, and acceleration becomes more pleasant due to the flat torque shelf (3000-5200 rpm). The automatic transmission algorithm is clear and logical, but the gears change too smoothly.

The chassis is tuned for comfort. This is reflected in the high smoothness of the ride on small and medium bumps. The suspension is very energy intensive, and as a result, durable.

However, comfort did not negatively affect handling - the steering is quite informative and allows you to feel the position of the wheels when turning the steering wheel, while rolls in turns are moderate. But, the desire to drive in bends is quickly discouraged by strong understeer, which manifests itself in the form of a sharp drift at the limit of the car's capabilities.

So, if after pumping a pear or something from the nozzle pipes when scrolling with a starter, nothing presses, then you have problems with mechanics: the most likely option is damage to the membrane (or cutting rings), the second option is a defect of the pump pump.

Besides the control panel, the second important interface between the system and the person is the monitor. In the new MMI, Audi has opted for a large 7-inch TFT display; it sits ergonomically at the top of the center console. A very high resolution of 800 x 480 dots and LED backlighting make the monitor extremely clear and contrasty - even in bright light, colors appear rich against a black background. The new central computer, control unit 1 for information electronics J794, carries out the functions previously assigned to six separate control units. Additional functions such as an SD card reader and a hard disk in the MMI Navigation plus make the control unit a true high-tech product. The second new device is the Radio R control unit. It combines the functions of the tuner and the audio system, which were previously divided between three control units. This reduces the total number of control units in the MOST system. Although the 3rd Generation MMI offers more features and equipment, the system requires less space and when fully equipped it even saves 4 kg in weight.

In 1997, spring came and Audi released a new body for the Audi A6 C5, they were already sold in the sedan and station wagon (Avant). In the new version, of course, the design was changed, but the silhouette and style of the "muzzle" of the car remained similar to all other Audi models, for example. The design was redesigned in such a way that improved aerodynamics of the car 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 automotive 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.

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

Exterior

At the 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 as wide as the radiator grille. The radiator grill, in turn, has a chrome edging around it. The massive bumper of the model also has chrome edging in some places, as well as round fog lamps.

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

The back 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 the chrome insert at the bottom. The rear bumper has a huge plastic insert and, in fact, nothing else.

Dimensions:

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

Specifications Audi A6 C5

As well as in the review of the previous generation, we will not describe in detail each TFSI engine, as there are simply a huge number of them. You can find out their characteristics from the tables below.

Diesel	2.5 l	180 h.p.	370 H * m	8.9 sec.	223 km / h	V6

The car's suspension is made entirely 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 applied at the back.

The manufacturer offered different gearboxes for the Audi A6 C5 (1997-2004), there is both a mechanic with 5 or 6 steps and a 5-speed automatic, and there were also variators 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 there are still some differences. At the front, there are decent heated leather seats with little lateral support. The back row received a sofa for three passengers. In the middle at the bottom there are pull-out cup holders. There is also an armrest with niches for small items. There is ample space in both the front and back.

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

The center console at the top has an emergency button and one cup holder that pops out at the push of a button. Below is a head unit operating on cassettes, these receivers 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 setting.

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

Price

This car can be easily purchased on 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.

Whether to purchase this model or not is 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 because of age.

Video

Audi A6 of 2004–2011 years of release most of all appeals to our buyer. Why? It turns out that many fans of this model claim that the modifications of this car released today began to resemble more a computer on wheels than a car. Of course, this affected their reliability, but this is not enough.

Model history

The Audi A6 in the back of the C5 has always been produced in two versions: sedan and station wagon. If earlier this was considered a generally accepted norm, today it is not. "Six", as amateurs call the Audi A6, has always differed from its eternal competitors from the German trinity by a good front- and all-wheel drive layout. Exactly what is needed for Russian roads.

Audi A6 has firmly established itself in the luxury car segment, not inferior in anything to its opponents. In addition, the "six" has always boasted cool versions of the S and RS.

So, the Audi A6 debuted in the fall of 1997, which already amazed experts with its design. But Audi A6 did not deserve such popularity as in Europe and America. This model has gradually conquered our country.

The Audi A6 has always traditionally been produced in sedan and station wagon versions.

Modifications

On the gearbox, after a 100-thousandth run, the pushing chain changes, the price of which is 11 thousand rubles. After this time, a BU, which costs 35 thousand rubles, can also go out of order. Every 60 thousand run it is necessary to change the oil in the control unit, a liter of which costs 850 rubles.

The independent suspension borrowed from the Audi A8 is durable. But the spring suspension will require serious intervention after 200 thousand kilometers. During this time, the struts and bushings of the stabilizer must be changed, including as well. On "Sixes" with pneumatics, the cylinders are capable of holding up to 120 thousand kilometers, and we must remember that the front ones change only in assembly.

What can you say here? Huge expense, if Audi A6, which will not pay off in any way. But this does not stop amateurs and they still pay tribute to excellent driving performance, powerful and economical engines, rich equipment and good noise insulation, although expensive to repair and maintain, but beloved by all Audi A6 or simply "Six".

Audi A6 (C5) 1997 - 2004 - a car in the best traditions of business class. Decent, solid, respectable. There is no excessive aggression, like the BMW 5-series, and there is no bombast and snobbery of the Mercedes E-Klasse. A lot of advantages. Few flaws. And all the same - the majority of buyers will pass by and will not turn around. And why? Expensive. Very expensive. And it's not even the cost of the car itself.

A short introduction

The second generation Audi A6 was produced with two body types: sedan and station wagon (Avant). There are more offers on the sale of station wagons on the Belarusian market, but there are also a lot of sedans, so there is plenty to choose from.
You can also choose based on the trim level. As befits a car of this class, the list of even the basic equipment of the Audi A6 is impressive: four airbags, power steering, front power accessories (glass + mirrors), ABS, central locking, height and depth adjustable steering column, separate climate control. Instances in which there is an ASR traction control system, ESP motion stabilization system, seat heating, an on-board computer and cruise control are not uncommon. The most equipped modifications can be recognized by the xenon headlights, leather interior and wood inserts on the doors and center console. In such a car, in addition to all of the above, there are such expensive options as a GPS navigation system with a TV tuner, an electric seat drive with position memory, a heated steering wheel and other “joys of life”.

Body and electrical equipment

The fully galvanized body is durable and non-corrosive.
Of the "electrical" problems, most often there are problems with the power windows (especially in the driver's door) and problems with the rods of the door locks. They are typical for cars manufactured before 1999. Sometimes the airbag malfunction lamp comes on. Most often, the cause is oxidized contact on the plug under the driver's seat. The same problems with oxidation of contacts are found in turn signals and wipers.

Engines and transmissions

The Audi A6 (C5) was equipped with V6 and V8 petrol engines. There is no structural difference between them, the difference is only in the volume and number of cylinders.

The 1.8-liter engine (125 hp, installed on cars until 1999) has problems with starting in wet weather. The "disease" is treated by reprogramming the control unit. Turbocharged 1.8-liter unit with 150 or 180 hp. dangerous for a potential buyer with a failed turbine (its service life is about 150 thousand kilometers). In a two-liter engine (130 hp), plastic elements of the crankcase ventilation system are often destroyed.

The most popular models on our market are models with a 2.4-liter engine - and for good reason. They are the most reliable. The servicemen gave the title of "most unsuccessful modification" to version 2.7 Bi-Turbo. Uneven engine operation, low resource, low maintainability are serious arguments against buying an Audi A6 with this engine.

Cars with 4.2 liter engines are rare in our country, and their only and main drawback, in addition to fuel consumption, is the high cost of maintenance.

The entire range of 1.9 liter diesel engines (110, 115, 130 hp), as well as 2.5 liter diesel engines (150, 155, 163, 180 hp) is represented on the Belarusian used car market. It is worth remembering that Audi diesel modifications are very sensitive to the quality of fuel and oil. 2.5 TDI engines often have leaks in shaft seals and gaskets, which indicates a clogged crankcase ventilation system. It should also be remembered that unqualified maintenance of the fuel system can lead to failure of the injection pump, which cannot be repaired (and its cost is comparable to the price of a used car - from 2500 USD).

All A6 engines have an enviable oil appetite. This is typical of the engines of this model, and if the engine "drinks" up to half a liter of oil per 1000 km, and for the V8 and the whole liter, then you do not need to call in to the service.

The guarantee of long and reliable operation of Audi engines is timely maintenance. The oil and oil filter on gasoline versions should be changed every 15 thousand km, on diesel versions - every 10 thousand kilometers. The air filter changes every 40 thousand km. Candles in gasoline engines take care of 30-60 thousand km. In addition to the above operations, one must not forget about replacing antifreeze - every 60 thousand kilometers or every 3 years. In some car services, it is recommended to change the water pump when replacing the timing belt (according to the instructions, this should be done every 90 thousand km). Such a measure is not necessary and the pump is replaced exclusively at the request of the owner. After 100 thousand km of run, the throttle valve comes out "from old age". The block cannot be restored, only replaced.

Both front-wheel drive and all-wheel drive quattro transmissions are reliable enough. There are no complaints about the operation of a 5- or 6-speed "mechanics", as well as to a conventional 5-speed automatic transmission. But the employees of a specialized service station recommend that you refuse to buy an adaptive Tiptronic and a Multitronic variator with the possibility of manual switching - the Tiptronic clutch resource is about 160 - 180 thousand km, and Multitronic had computer failures.

Suspension and braking system

The differences between the mono-drive A6 and the A6 quattro are in the rear suspension. For front-wheel drive, there is a semi-independent beam at the rear, for all-wheel drive there is an independent double wishbone. Both versions are reliable, but expensive to maintain. Suffice it to say that the ball joints change only as an assembly with levers (four levers per wheel), and they have to be changed every 40 - 80 thousand km, depending on the driving style. Front shock absorbers "nurse" 80 - 100 thousand km, rear - 110 - 120 thousand km.
The braking system of the Audi A6 is generally reliable. The only drawback is fluid leakage at the attachment points of the rear brake hoses to the calipers. Replacement of the front pads is required on average every 30 - 40 thousand km, the rear - after 50 - 70 thousand km. Front brake discs withstand 60 - 80 thousand, rear - 120 - 140 thousand kilometers.

Let's sum up

Audi A6 (C5) 1997 - 2004 the car is good, but not cheap. Therefore, when buying, it is worth considering not only the price of the car itself, but also the cost of its maintenance and repair. It is also worth remembering that the A6 (however, like other cars of this brand) is demanding on the quality of fuel, oils and needs qualified service. However, in fairness, we note that this is inherent in all business class cars.

Advantages

Excellent corrosion resistance
+ Rich configuration
+ Wide range of engines
+ Many offers on the used car market
+ All-wheel drive quattro (some modifications)

disadvantages

High cost of cars, maintenance and spare parts
- Demanding for timely and high-quality service
- Picky engines for oil and fuel quality
- Increased oil "appetite"

Interestingness

Despite its high reputation, the Audi A6 (C5) has received numerous reviews. For example, in February 2007, a massive service campaign took place in Europe that affected more than 870 thousand cars Volkswagen Passat, Audi A4, Audi A8, and Audi A6 1997-1999. The reason for the recall was the rapid wear of the protective rubber casing of the front axle, which could lead to accelerated wear of some of the front suspension units and potential breakdown of the supporting structures.

And in the United States, about 74 thousand Volkswagen Passat, Audi A4, and Audi A6 2003 were subject to recall. with V6 engines of 1.8, 2.8 and 3.0 liters. The detected malfunctions were of a critical nature, since they can cause a sudden engine shutdown due to a defect in the wiring of the fuel system.
