Welcome! Give your local dealer a call-they will let you have sample prices. They may require a sample registration number from a particualr A2 (I know that is the way Volvo work) so try and found out from the Audi used car search.
Do a fourm search, it may pop something up! I did read recently someone doing a cambelt and service etc (quiet a high mileage service obviously for the cambelt to need changing) and I think it was neary a grand! But then with VSI if you are only paying for other services every 20k miles it all evens out over the lifetime ownership.
