Disadvantages of the Audi BUG engine
Up to 100,000 kilometers in the engine, with the exception of potential disturbances from the intake manifold flaps;
The injection pump belt frequently bursts during this run, usually with no repercussions;
A piezo injector defect caused the pistons to burn out during the initial years of production;
Although the timing chain can last up to 300–350 thousand kilometers, replacing it is highly costly;
The EGR valve or particulate filter may get totally clogged at high mileage.
