Hi, It's oil and filter change time for my 65 plate A4 Allroad 190TDi, and I want an accurate reading when doing it. I read a few posts on here about people getting a "real" dipstick to do this, but having phoned my two local Audi dealers they say there's no part number for it and you have to use MMI ?? I don't want to rely on MMI and risk overfilling it. Are they talking a load of ******, or can you genuinely not a get a dipstick for my car ?? It's a CNHA engine. Cheers, Graeme.
