I have found an Audi A4 2003 1.8T and was looking for some advice from experience A4 owners. The car has done less than 50k miles and has a full service history. I have read of issues with sludge problems and was wondering what to look for specifically relating to A4's? Are there obvious signs of this sludge issue?
Cambelt hasn't been replaced yet either, I have been told that 75k to 100k is the time to do that but the car is 10 years old so is it worthwhile changing it now?
