Hi Audi Bros,

Can someone enlighten me on the problem I'm encountering on my 2004 A6 1.8T. As I move off from stationery, the engine "shudders" at 1500 rpm but above that it's fine. It is especially prominent when moving up slope.

Brought car to the agent and was told it is the input shaft of the auto transmission that may be faulty. However that may not totally solve the problem.. They warned!

Need advice on what other alternatives and possible problem other than that mentioned by the agent. Thanks.
