Should I be worried?

[briang9]

nothing to worry about Jim, mine has done it from day I got it, if you remember I had the oil pump changed and it made it a bit better for a while, and its also better just after an oil change, the Audi Tech bulletin and this thread puts your mind at ease, with hind sight I probably wouldnt have bothered getting the oil pump replaced on mine but apart from a dent in the wallet can only be a good for the engine I guess.
