Since buying my A4 convertible, old but nice.... have been looking at various Forums. Honestly this one stood out to be the best, others simply failed to answer questions raised by the members. Sorry, I was under the misunderstanding that forums were for the mutual benefit of all. In time we all have something to share. Anyway, Hello and for my part, when I can I will help others. To this end, my car has only 60,500 on the clock and seems to have been used rarely over the past 12 months. The Auto gearbox is having a bit of a wobbler. Initially when starting off a judder could be felt, but now I am having difficulty with the autogearchange itself. On browsing information on the net it appears the car needs a good change of gearbox oil. Any ideas? Many thanks. Cheers, Ray.
