At the price the stealers want i dont think its worth it, i recenlty had my belts changed at jabba, they did the aux belt, tensioners, water pump (changed to metal type) found that my dv was faulty and it all came to just under £400, they also showed me all the old parts. Audi wanted £600 for the cam belt and the water pump and i doubt they would have noticed the dv. I also found out that a stamp is worthless as the last stamp in my book audi had no record off, even though they keep there stamps under lock and key (so they told me).
