My A6 20tdi 2006 with 25,000 miles is due for a service in 200 miles, I have phoned three Audi main dealers and got three differant anwsers. My question is how much is the service and what do you do? All asked for the number plate and checked on thier system what was to do. The most annoying was the guy form Audi Amersham who first quoted £275 for an A service then when I asked about the £99 service on the internet his said it is the same but with less visaul checks!! So I would appreciate any help or thoughts.
