I am a new A6 owner, its a 2.5 TDI SE avant with 180k on the clock. It has full service history with some of the first service stamps being the long life service which i now know from reading on here is not a good thing. I would never choose to extent the distance between oil changes but hey ho. I am going to service the car myself as much as possible, i tend to do this on my other car, girlfriends car etc... It is due a service in circa 1k, i am going to follow the guidance at the front of the service schedule document but is there anything over and above this that i should check for? Other than taking the heads off and checking cam wear which i believe is an issue with this model? What is the best oil for the job with these engines? Do many people on here service their own car? All help welcomed.
