Good afternoon folks,
My 57 plate Quattro is sitting at 36k miles, and according to the service book has not had a haldex service. I have looked up doing it and it does look really easy to do, however I phoned up Aberdeen audi and they want £70 to change the oil and filter (although have to make sure this does include the filter). In terms of service interval I believe it is 40k miles between haldex oil and filter changes. Is this correct? If this is the case I think I will just get audi to do it. If it is more regular than this I might do it myself.
Also, does the rear diff require an oil change as well? If yes what is the service interval and type of oil that is required?
