I've got a TDI (110) on W plate/2000, which is coming up to it's next service. The mileage is approaching 140K and I'm really starting to wonder if getting the car serviced by Audi to get the magic dealer stamp is really going to effect the value, in light of the mileage. My thoughts are save the £300 the next service will cost and do the service myself. What are other people's thoughts on this? The other thing is that the car is on AVS service plan. As far as I know, only a dealer/someone with access to diagnostic kit can reset the service to AVS and also interogate what the car needs to have done - is this right? Lastly, if I quit AVS (and yes I know most people hate AVS!!!!) what type of service should I start with - a 20K service? i.e. all filters changed and full inspection.
