Audi 100 45 DIY repair

In detail: Audi 100 45 DIY repair from a real master for the site my.housecope.com.

The Audi 100 belongs to the middle class and has an all-metal monocoque body of the sedan or station wagon type.

The cars are equipped with a whole range of four- and five-cylinder petrol engines from 1.8-liter with 100 hp. up to 2.23-liter turbocharged 200 hp

In addition to gasoline engines, there is a family of diesel engines for the Audi 100.

Four- and five-speed gearboxes or an automatic three-speed gearbox are installed on the car.

The basic model of the car has a front-wheel drive layout, but there is also a modification with all-wheel drive.

The steering is a rack and pinion type, there are modifications with power steering.

The brake system is a double-circuit with a hydraulic drive, the front brakes are disc, the rear brakes can be drum or disc (depending on the engine power). Depending on the equipment, the vehicle may be equipped with ABS (anti-lock braking system). All modifications have a booster installed in the brake system.

The car is equipped with a safety steering column, some cars (depending on the configuration) are equipped with an airbag for the driver.

The car has an exceptional body from the point of view of aerodynamics (the sedan has a coefficient Cx = 0.3, for the station wagon Cx = 0.34). This is achieved thanks to the smooth body contours, without sharp transitions, a large slope of the windshield and rear windows, as well as the original design of the side windows. The side windows are installed on the outside of the door frames, flush with the body pillars. This design was used for the first time in the world on a production car.

During the development of the body, much attention was paid to corrosion resistance. The parts most susceptible to corrosion are made of zinc-metal; non-load bearing parts are made of plastic.

The Audi 100 series began to be assembled back in the late 60s. At present, the Germans have abandoned this name in favor of the more well-known A6 nomenclature today.

The last generation of "weaving" made its debut on the market in 1991. At the same time, a sports version of the model, designated the S4 symbol, appeared, under the hood of which gasoline engines were installed - a 2.2-liter R5 or a 4.2-liter V8.

In 1994, the Audi 100 C4 was redesigned. The car received slightly modified headlights, taillights, new mirrors and bumpers. The interior was also slightly refreshed.

Along with the restyling, a new designation was introduced: the name “100” was changed to A6, and the sports modification received the S6 index instead of the S4. Production of the Audi 100 / A6 C4 ended in 1997, when the more modern, more technological and more attractive Audi A6 C5 was released.

2.2 R5 Turbo (230 hp) S4 and S6 versions;

4.2 V8 (280-290 hp) S4 and S6 versions;

4.2 V8 (326 hp) version of the S6 Plus;

Two decades ago, Audi made sure that the choice of engines for the A6 was as large as possible. Many people, deciding to buy, cannot decide which of the motors suits them best.

The 4-cylinder engines are not worth paying attention to, with the exception of the 140-horsepower version of the 2-liter unit. They are very weak and therefore have to consume too much fuel.

Motors with a working volume of 2.0 liters and a power of 140 hp are considered the most optimal. and 2.3 L R5. The V6 and V8 are an option for true A6 aficionados who don't care about either high fuel consumption or high maintenance costs.

Regardless of which engine you choose, you will have to come to terms with possible malfunctions. After all, the car is already very many years old.

What is failing? Most often, ignition coils and a flow meter. Timing belts are also inconsistent, which do not withstand the period allotted by the manufacturer. The optimal replacement interval is 60,000 km.You should also pay attention to the valve cover - oil leaks often occur from under it.

In addition to gasoline engines, the Audi 100 also received diesel units. Compared to modern diesels, their durability can be called "eternal". The 2.4-liter unit creates the least problems, slightly worse than the 2.5 and 1.9 TDI.

If you need the most dynamic option, then you can safely choose the top-end 140-horsepower 2.5 TDI (not to be confused with the unreliable 2.5 TDI V6 engine of the later generation).

For such a large car, the 2.5TDI is best suited. The rest simply do not have enough strength. Malfunctions are most often associated with old age and relate to: the injection system (pump and injectors), the turbocharger, as well as the flow meter.

Depending on the type of drive, the Audi 100 can be front-wheel drive or four-wheel drive. Transmissions: 5 or 6-speed mechanics, as well as 4 or 5-speed "automatic".

The suspension is a classic design with a MacPherson strut in front and a torsion bar in the back. The all-wheel drive versions on the rear axle are equipped with multi-link suspension.

Reliability and high quality have always been the strong points of the Audi 100 / A6, which is why motorists love this model. Despite its age, the A6 C4 holds up quite well, but it is not without its drawbacks.

Often the steering gear fails. With age, gaps appear, and the rail begins to knock. The power steering pump is also rented.

The starter and the generator do not differ in endurance. But competitors are no better in this regard. A thorough check of the condition of the cooling system is necessary.

In the event of its failure, the cost of repairing the engine is inevitable. In versions with Quattro all-wheel drive, higher costs for rear suspension repair must be taken into account.

Often, such elements as the air conditioning compressor, the electric window regulator, the sunroof opening mechanism, the thermostat, various relays, the temperature sensor and the parking brake mechanism are naughty.

What conclusions can be drawn.

The Audi 100 / A6 C4 is an almost perfect German car that, despite the years, not only looks good, but is also quite reliable.

A big plus is the availability of inexpensive spare parts and rich equipment of young specimens. The wide range of engines and suspension settings deserves special praise.

But there are also disadvantages . V6 and V8 engines require astronomical fuel costs. Fortunately, finding a copy in decent condition is not too difficult a task.

Below will be presented articles that were posted on the network by car enthusiasts of the Audi 100 and Audi A6 C4 bodies, where motorists encountered certain problems during the operation of the avdotya and managed to fix the iron friend on their own.

This article will discuss how to remove the auxiliary drive belt for Audi 100 cars, A6 C4 body and 2.6 petrol engine displacement.

I will make a reservation right away that we will do all the work without draining the coolant, parsing the front of the car and completely removing the timing belt.
