morning all had my a4 2.0 tdi for 2 years now and the service light has come up. My cars done bang on annual 10k miles a year so now its 2 years old with 20k on the clock and due its first service. I've spoken to a few audi dealers and the information they're giving me is varying greatly. I've been quoted from £170 - £334 ranging from an interim service to a major service. Im totally confused as to what is the recommended schedule for my car and what i should be going with. Please help.
