Hey all, another servicing thread i'm afraid! My a3 1.6 (2001) is due for a service. I have got two quotes for 400 and 420 pounds which is from the two audi garages near by me, which seems alot to me, but i do understand thats quite the norm for audi's If I agree to change the oil myself do you think that the audi garage will agree to knock off a chunk of the service cost and still give me a stamp in my log book? Also - i have a fsh all with audi stamps in it (currently on longlife service at 35k) having a service every two years. Will getting a non audi stamp in my log book significantly devalue my car, or will it make a difference to the life of the car?
