Disadvantages, breakdowns and problems of VW ADZ
The main problems for owners are caused by failures in the operation of the mono-injection system
Regularly here you have to deal with leaks of lubricant or coolant
Due to throttle contamination or air leaks, engine speed often floats.
More often than others, the lambda probe and the antifreeze temperature sensor fail here.
By 200 km, rings or caps usually wear out and oil consumption appears.
