Hi guys, Since I'm new to my A4, I've got a couple of burning questions after driving it around for a week... When I'm in first gear in stop-start traffic I've noticed what can only be described as the occasional 'rumble' from the back end. It sounds like it could be fuel sloshing around in the tank as it doesn't happen every time - has anyone else noticed this or should I get it checked out? There is a bit of 'lumpiness' when the engine is idling. I'm guessing that it should be super smooth... Any ideas what the cause of this could be and, again, should I get it checked out? ...It's a TDi 140, by the way.
