2004 A3 TDI 65k: The head gasket was replaced around 400 miles ago and is due an oil change. Wheres the cheapest place to get changed. I was told Kwik Fit do a cheap service, but not sure on prices and quality? I always regard them to be a bit Mickey Mouse. Got a quote from my local Audi Specialist Just oil Change and Filter, no flush £60+VAT. Is that reasonable?
