 I purchased 2 2003 Audi A4's at the same time. Just as the warranty expired, similar defects appeared in both cars.  In just over two years, almost everything has gone wrong with both cars. They are both lemons. The Audi dealership we went to charged me almost $3K for 2 visits in which they couldn't diagnose the problem. The turbo exploded 2 weeks ago in one of them and damaged the engine in the process. Both cars are a money pit, and I am attempted to dump both & absorb the loss. Audi corporate apologized for my frustration & loss & asked if there was anything else they could do today. DON'T BUY THESE CARS!!!!
