Phoned my local VW (Advantage Volkswagen, Stirling) today and have been quoted a price of £400.35.
I never asked if this included the water pump (but judging by marty341's price, it wont) will call back tomorrow to find out.
I have a mate thats a mechanic, I might ask him to do it, although I would miss out on the stamp. Do you think it is worth paying the extra, going to a VW dealer and getting the stamp, for when the time comes to sell the car?
