VDK,
Sorry to hear about your experience.
Last weekend I had the 32k service performed on my car, and the dealer appeared to do everything asked of them and topped up all the relevant fluids and did the pollen filter change etc. Car still drives as smoothly as the first day I got it.
As far as I know, it is standard practice for dealerships to set the service interval counter reminder to 8k (rather than 16k), so as to ensure oil changes are done more frequently (as well as generate regular cash revenues for dealer). I ignore the reminders and you can reset the reminder yourself (search on vwvortex.com for procedure). Can't see the point of 8k oil intervals if you're driving on Castrol Syntec oil.
Dealership still doesn't wash cars post-service, but that is something I've got used to by now.
Don't let the dealership experience spoil your enjoyment of the Rabbit.
