My father has an Audi A2. It’s 5 years old but has only done 20k miles. It’s due an MOT soon, and the local Audi dealer (who are doing the MOT for free) have called up recommending he replace the timing belt (about £300) because they ‘rev it up’ during the MOT. When he told them it’s only done 20k miles they said it’s done on time now, not mileage, and the belt should be replaced after 5 years.
He’s a bit concerned as obviously a timing belt failure could be nasty. He’s done a bit of research but can’t find any official guidelines on timing belt replacement, not even from Audi themselves.
Question: Are the dealers chancing it or should he buy a new belt?
