I'm considering upgrading my 1994 Audi 80 1.9 Td, for a 1998 Audi A4 2.5 TDi v6 estate after an accident, however the new car has 171,000 miles on it. It has an absolutely flawless service history, with everything being changed on time, and parts replaced ahead of time (e.g. water pump - at the same time as cambelt for easy of assembly). Also the last 90,000 are all motorway miles (I know the owner). It looks and drives good.
How long do people think this engine will live, what is the most likely problem with such a high mileage car? The turbo and clutch/gearbox are original.
cheers
