The most common motors of the A4 3 generation are atmospheric 2.0-liter and turbated 1.8 and 2,2-liter petrol engines. A common problem with the 2-litre turbo-motors up to 2007 is the wear and tear of the TDDD pushrod and over 100,000 odomes. km The engines with turbines also have a common defect in the ventilation of the crankcase gases, resulting in oil flowing from the valve cover. Not a very large resource is characteristic of the ignition-ignition-it rarely exceeds 120 thousand. km Another common problem is the increased oil consumption (up to 1 litre per 1000 km). Diesel motors are more reliable and do not cause any problems up to 150-200 thousand tonnes. km
