It says in your service book what the interval is for the cambelt (toothed belt).
People will tell you all sorts but go by the schedule in the book. Its 80k but cant remember if its 4 or 5 years.
Don't skimp on it its not a nice feeling to know your engine just ate itself :-(
as i said but if his service book is the same as mine it will state to change it at 125k miles audis have now revised this to 80K miles
hi mine is a 57 plate 2.0 tdi se when does the cambelt need changing?
