Audi A6 of the 1994 model actually retained the filling of the previous hundredth model, while A4 became a completely new machine. Their platforms came closer in 1997, with A6 updates. We will talk about all three. (
Oil canister - in the engine, the other - in the trunk

Multicked engines are very demanding on oil level. If on old motors even riding with a dry probe, often left the hands, then the fall of the level below the minimum is unacceptable. The hard sound of the engine is the first alarm signal (the emergency oil pressure lamp may not light up). First of all, the timing shafts wear out, and the jammed shaft on a multi -valve (five valves on the cylinder) engine leads to a break of the belt and meeting valves with pistons.

When the timing belt breaks, only the old eight -valve engines of 1.6 and 2.0 liters do not suffer. The rest will put the owner for a decent amount. Original belts in the mass nurse the set 120 thousand km. Early cliffs are, but the reason is usually hidden in adjacent nodes. For example, in jammed rollers or pomp. After 90 thousand km, it's time to pay attention to it: noise or backlash in the bearing - an indication for replacement. Simultaneously with the belt, its tensioner and video are changed.
On the V-shaped engines after a run of 120-150 thousand km, the gaskets of the cylinder heads often begin to flow. Before replacing them, be sure to check the plane of the haltering surfaces of the heads. When overheating of the engine or improper tightening of fasteners, they will jar. Small deviations are corrected by grinding on the stove.

If suddenly, the idle speed began to walk (it is difficult to not notice the gas stroke with the gas pedal) - get ready for the replacement of an expensive throttle knot. This usually happens after 100 thousand km. Sometimes the defect can be cured by flushing, but this is rather an exception. After replacement, it is necessary to agree on the node with the engine control unit using special equipment. This will be required when the battery is turned off.
Many cars come for repairs after home tuning. For example, the supply of fuel on a two -liter eight -valve engine ABC is regulated by a dispenser. The cogs on the case look very seductive: the receipt fell - they twisted back and forth, and the car drove. Only with black smoke from the pipe. Sometimes, after such tuning, it is not easy to restore the correct adjustments even to a professional.

The factory protection of the engine is plastic: from dust and light touches. Meanwhile, an aluminum pallet even with a small blow can give a crack through which hot oil will flow out for a few kilometers. On A6 after 1997 and A4 there is an enhanced composite protection - it holds a blow to medium force well. For six until 1997, you can order the original steel. There is also a similar product of Russian production on sale, but the fastening is selected unsuccessfully - to the transverse thin -walled pipe in the lower front of the motor compartment. When hitting an obstacle, such protection can pull the pipe and the front of the car, bending the radiator.
Front or complete?

Clutch on all machines is no better and no worse than classmates, it serves 120-160 thousand km with calm driving. Women often turn out to be an unexpected enemy, or rather, their hairpins are elegant, but not at all suitable for driving.
The gearboxes are not delivered. The machine requires replacing oil and filter every 50-60 thousand km. Even after a light blow to a stone or ice, be sure to check the integrity of the aluminum pallet of the manual crankcase. The machine is not so sensitive, its pallet is steel.
The bearings of the front hubs on six until 1997 and four serve on average 60 thousand km, the rear - 80 thousand km. On A6 after 1997 - 150-170 and more than 200 thousand, respectively.
Black metal
The front suspension A6 of 1997 and A4 is four -leaf. Two upper and two lower aluminum levers with ball hinges provide comfort and excellent handling. But, as you know, you need to pay for such a combination, and audi is no exception. On Russian roads, the backlash in the hinges of the lower levers usually appears already by 30 thousand km of run. The upper levers last longer - 50-60 thousand. The least durable racks of the old stability stabilizer of the old sample on A4 (with ball fingers) are often enough only 15-20 thousand km.

In the front suspension of the old A6 - an ordinary McExeson. Shock absorbers here serve much less - a year and a half. Symptoms - knock, backlash, leak on the rod. Also, over time, the backlash appears in the axial bearing of the upper support. But the remaining elements are much simpler and more durable. For Russia, this more rigid suspension is just right. Silent-block in the only lower steel lever will have to be changed after 40-50 thousand km, after 30-40 thousand-the rubber supports of the stabilizer rods. That's all.
The rear suspension of the front-wheel drive is very simple: a steel beam on two silent blocks. With wear, it is cheaper to change them with a couple. The approximate line is 60 thousand km. On Quattro is a complex multi -link, more than ten silent blocks. The walker is not bad (comparable to the beam), but the bulkhead is quite expensive.

The rear pads serve about twice as long as the front, and one disk (front or rear) is enough for two sets of pads. But checking the performance of the rear brake is better more often - every 20-30 thousand km. If the bracket has lost mobility, disassemble the mechanism and apply high -temperature lubricant to the guides. If the torn anthers that fall under them and water will quickly get out of order do not notice in time - then you will have to buy a caliper assembled.
By replacing the pads with A6 with the V8 engine, remember that they are asymmetric; Having mixed them up, you risk being left without brakes: with a jammed caliper and disks blue from overheating.
The steering tips are enough for 60-80 thousand km, there are no complaints about the rail. The secret of longevity of the GUR is timely and competent maintenance. It is more expensive to add something to yourself in the tank for the steering wheel. Audi allows only the proprietary G002. It is better to change it every two years, and with a strong darkening and smell of the paired - earlier. As a rule, the smell appears when the steering wheel is held for a long time in the extreme position - while the parts wear intensively. The swearing pump is no longer saved by the replacement of the liquid, sooner or later it will jam.
It seems to be a trifle ...
Moisture under the mats of the salon in the audi will not spoil the body - galvanized, primed and well -colored metal resists rust for years. But the electrician is not so impregnable - for example, the ABS block connector under the rear seat or the sensors of the side pillows, also attached to the floor. Elementary care (Korytza rugs under the feet and drying of the salon in the sun) will pay off a hundredfold.
Refused the microding microdist in the lock unit? Order a whole castle, the company does not exchange according to trifles. The same when breaking the glass of the windshield or a break of the cable is only a mechanism assembly.
It is difficult to protect yourself from cracks on headlights. In the new generation, six headlights are closed with polycarbonate (plastic) glass. It is much more durable, and scratches can be removed by polishing.
The body, as we have already said, does not succumb to Russian salt. But the enamel from the front arches, especially on the machines of the first issues, peels quickly. True, rust raids appear soon - if you paint over in time, the machine will save the presentation.
REST ONLY IN OUR DREAMS

When choosing a car in the market, pay attention to the factory stickers on the hood and the radiator frame. If the body parts are relatives and unpainted, the pieces of paper are glued evenly and tightly. Their absence is an almost one hundred percent guarantee that the part was changed. Some masters are cunning: re -switch the signs to new details. But once a lagging corner is given a cooled sticker. Also check whether the place with data on the configuration is in place: it is in the niche of the spare.
A possible culprit of oil starvation on 1.8 liter engines is a check valve.
The gap of the crankcase of the engine is afraid. But you should not attach protection to this pipe.
The V8 engine is the most powerful in the family.
A6 front suspension until 1997: there is nothing to break.
New A6: More details - more expenses.
The rear caliper must be monitored.
And do not pull the handbrake.
A sticker with configuration data is in the niche of the spare wheel.
The factory sticker tells - the part was not changed.
