Are 350,000 km for an Audi V8 basically a problem? According to my information, 2 years ago (no idea how many km in between) a timing belt change was made, as well as new brakes installed. Otherwise, the details are still in the dark at the moment; it is a 4.2 with automatic, built in 1992. Achja, pricing is between 2 – and 2,500 €.
