I'm trying to find out when should I book my A4 2.0 tfsi for a service. I bought it used from audi dealer a year ago. I read on audi website that it all depends on whether it's flexible or fixed schedule so 9,000 or 19,000 miles. I've already got over 22,000 miles on the clock so I called my local audi and they said there is no information on their computer system to tell them when to book it in and said to call the dealer where I bought the car from. So I did and they couldn't tell me anything more other than the car will tell you when time comes. When I checked the MMI it says oil change in 2100mi so that will be at 24,500mi and next inspection in 11,800mi so at 34,000mi. Does this sound correct? Seems a lot different to what audi website says.
