Audi AAH
The main complaints of car owners with such an engine are related to oil consumption.
The Audi A4 is a middle-class car produced by the German car manufacturer AUDI AG. Audi A4, and until 1995 Audi 80, is the successor to the F103. In 2011, the 5 millionth copy of A4 rolled off the assembly line of the plant. Today the sales volume is so high that the Audi A4 is ranked 4th in terms of the number of cars produced in Germany. The A4 is made with 4 body types – two- and four-door sedan, convertible and 5-door station wagon.
The Audi A4 was offered with 65 engines since 1994 (35 petrol, 30 diesel). Displacement ranges from 1.4 to 3.1 liters, power output from 90 to 272 hp. 32 use a timing chain and 47 a timing belt. 48 are turbocharged. The longest rated lifespan belongs to the Volkswagen 1Z (about 450,000 km).

The main complaints of car owners with such an engine are related to oil consumption.

This is a very reliable motor and breakdowns happen only at very high mileage.

Most of the complaints on specialized forums are related to progressive oil consumption. Consumption appears closer to 200,000 km after the wear…

This simple and reliable power unit does not often bother its owners.

The most problems are caused by the chain tensioner, which is also the phase regulator.

This power unit is prone to oil and antifreeze leaks, especially after overheating.

Very often the turbine fails due to coking of the lubricant in its supply tube.

The whole life of the owner of a car with such an engine is spent in the fight against oil consumption.

Most of the owners' complaints about this engine relate to high oil consumption.

The most famous problem with the second generation EA888 turbo engines is oil burn due to pistons with thin rings, as well…

The most famous problem of this turbo engine is high oil consumption.

The sophisticated CR Bosch system with piezo injectors does not tolerate bad fuel.

The main problems of this engine are associated with a drop in oil pressure in the system.

Most of the breakdowns of this motor are associated with a drop in oil pressure in the system.

In the first place are failures in the operation of a modern CR system with piezo injectors.

A reliable turbo engine with a long life, but only if you do not save on maintenance.

At the moment, the motor has proven itself well and there are only a few failures on it.

At this point, the only weak point of the engine is the short-lived flywheel.

While the motor has proven itself well and all the failures described below are single.
