Audi 100/A6

We used Audi 100 list of possible defects is much shorter than many other models. The most striking thing in cars Audi - this is their extremely high corrosion resistance. Since September 1985 the manufacture of machines used fully galvanized steel. Therefore, the cause of rust can become a non-professional repairs after an accident, or very poor care of the car. Paint finish is also durable. Inside the cabin immediately catches the eye of its capacity. There are many places along the front and rear, good trunk, good ergonomics. The only thing that is a bit confusing, so it's hard seats. Fabric lining - high quality, strong, dark colors. In vehicles in 1991 marked the aerodynamic noise (wind whistling in the front doors) that are fixed in any car repair shop by a simple adjustment. At the same cars that were released since 1991, almost no external noise penetrating the cabin. Ride comfort is undeniable, but in no particular problems with parking as well as in cars set to light and precise steering with hydraulic booster (in cars with 4-cylinder engine can be set for an additional fee). Only in the release of the 1991-1992 cars. sometimes there is leakage of hydraulic oil. Suspension is not enough soft, with fast driving feel their response to small bumps. For small defects can be attributed cabin vibration and pedal unit speedometer (especially at low speed) in the diesel versions that were released in 1991-1994. In the turbocharged version of the S4 wear out brake discs. The point was to fix the spring of 1993, picking up the new disks with the "classical" calipers, as well as in versions S4 V8. Parking brake in automobiles of all years of manufacture hard and has a tendency to deregulation. Mechanics car is reliable, all working parts are designed for long life. Even at high rpm engines Audi work less stressful than, say, four-cylinder unit Mercedes. Nevertheless, they have some shortcomings. For example, in vehicles with a 2-liter engine oil leak occurs on the rear oil seal crankshaft. And in the 1991 release machines with 6-cylinder power unit - a large consumption of oil due to improper installation of piston rings and, in addition, leakage of oil from the cylinder head gasket has sometimes after driving 40,000 km (car registration in 1993, established an improved gasket) . Instances of 1991-1992. recorded noise timing belt tensioner, and machines of all years of registration - the tendency to form deposits on the valves in city driving. The version release S4 1993-1994. with a V8 engine deposits formed at the spark plugs. Very big trouble can occur in automobiles version 2.5TDI 1991-1993 gg. - Sudden engine stalling due to a malfunction in the computer control the fuel injection system, which cuts off the latter. Furthermore, we know a few other cases stopping the engine (though rare) for the same reason in the cars launch in 1994 this version 2.5TDI with 140-strong unit, and almost all versions of the 5-cylinder petrol engines there are failures in the fuel pump. In the release version of 1991-1994. with a 2.5-liter engine marked the failure of the timing belt due to poor assembly shoe tensioner (belt is a slight offset his one-sided wear and premature failure). The Audi 100 first editions with a 6-cylinder 2.8-liter engine also had problems with the strap (similar to the pulleys), and newer vehicles are equipped with a separating pulleys. On versions with the 1.9-liter engines and engine 2.5TDI 115 hp produced before 1995 is unstable motor running in a hot state in the range of 2000-3500 rpm because of incorrect information supplied to the computer control fuel injection system. The problem was solved in May 1995. In automobiles release 1995-96. with the same engine (its capacity in 1995 increased to 140 hp) is possible coolant leak, and because of this - overheating in the event of a long trip. Overheating can also cause damage to the cylinder head. The problem was solved in September 1996 (from now on set head gasket, made of another material). In addition, the release version of the S6 1995 with an 8-cylinder engine failures reported in the pump cooling system (sometimes even after covering 30,000 km), and in automotive output in 1991-1994. - Refusals electric fan heater. The second problem is solved in a model of the A6 (1995). Work the gear lever is very pleasant, although the transfer of gasoline into longish versions (except for versions S4/S6). In Version 2.4D engine with gearbox vibration in the neutral position lever. A turbocharged version of the S4 and the first release of this version with an 8-cylinder engine (1991-1993). 25 per cent of cars have problems with the output shaft bearings in the range 45.000-70.000 km run. This can lead to the need to replace the gearbox (if all the costs of replacing the firm takes on Audi). Problems with the electrical equipment is almost there. Only in cars 1992-1993. diesel-powered 2.4 liter alternator can fail: it will be changed after the run 60.000-80.000 km. And the machines in 1991-1993. Cracking the case of rubber plunger remote control unit with central lock. In addition, vehicles produced before 1991 knocked the hatch (from 1991 flaw corrected). When buying a car is recommended to disconnect Audi and check for corrosion on high-voltage wire coming from the ignition coil to the distributor. In case of contact corrosion must be thoroughly cleaned, otherwise malfunction may occur in the ignition system. What to prefer? Version 2.3E, produced in 1991-1994: 5-cylinder engine with 133 hp very durable, its characteristics are satisfactory, but without any gloss. Version 2.8E with engine capacity of 174 hp: a "soft", restrained and elegant, well-equipped. S4/S6 version with 8-cylinder engines: powerful, great cars with excellent equipment and an integrated gearbox. Version 2.5TDI: very "low profile", although it has several disadvantages. If you are going to buy it, it's better to give preference to vehicles with the release of 1994 - will have less trouble with the electronics (this version comes with a 6-speed transmission and engine power of 115 hp (from 1995 - 140 HP )). In any case, the most interesting are well maintained cars, especially the version with an engine capacity of 2.3 liters and 136 hp (1990 - 133 hp). As for the all-wheel drive versions (Quattro), then this car is pretty heavy and requires a powerful engine. If you're not going to go often on snow-covered terrain, then you should give it up. An interesting modification to buyers of used cars is also a Audi 100 Avant (station wagon). Models Audi 100/A6 very reliable. Machinery output from the end of 1990 to compete with Mercedes cars of the middle class and BMW 5-Series. TROUBLESHOOTING Engine formation of deposits on valves in city driving. In cars 1991-1992.: Noise timing belt tensioner. In the version of S4 1993-1994 gg. engine V8: the formation of deposits on the spark plugs. In version 2.5TDI 1991-1993 gg.: Sudden engine stalling due to computer failure controls the fuel injection system. On vehicles 1994 and version 2.5TDI with 140-horsepower engine: a sudden stop of the engine due to a malfunction in the computer control fuel injection system. In version 2.5TDI 140 hp 1995-1996.: Deformation of cylinder head gasket, coolant leak. The lubrication system in the car with a 2-liter engine: oil leak on the rear oil seal crankshaft. In vehicles in 1991 with a 6-cylinder engine: big oil consumption due to improper installation of piston rings, oil leak in the cylinder head gasket has sometimes after driving 40,000 miles. Cooling System Version S6 1995 with an 8-cylinder engines: a pump failure in the cooling system (sometimes even after covering 30,000 km). In cars 1991-1994.: Electric fan radiator failures. The power supply system in versions with a 5-cylinder petrol engines: a failure in the fuel pump. Transmission in the turbocharged version of the S4 and the first release of this version with an 8-cylinder engine (1991-1993.) Problems with the output shaft bearings in the range 45.000-70.000 km path that could lead to the need to replace the transmission (about 25 per cent vehicles). Steering in cars 1991-1992.: Possible oil leak from the booster. Brakes in the turbocharged version of the S4 release until the spring of 1993: accelerated wear of brake discs. Body in car 1991: The aerodynamic noise in the front doors. Electrical equipment in the cars produced before 1991: the sound of the roof hatch. In cars 1991-1993.: Cracking the rubber plunger the remote control central locking. In cars 1992-1993. diesel-powered 2.4 liter: possible failure of the generator (to be replaced after the run 60.000-80.000 km).
