    OK, I guess the absence of replies means it isn't a common fault then . . .

    Could it be the length of time between oil changes with the variable
    servicing?
    It has always been serviced when the computer says it is due.

    Worries me a bit what has happened to the metal which has been worn off the
    cams - could it be lurking in the big end shells wearing them out, or would
    the filter have caught it adequately?

    Anyone any thoughts?

    TIA

    Could be a lot of things. Factory defect, type of oil used, change
    interval, driving style could all be factors. I think most of us change
    the oil more often than the lights tell us to. I probably change mine
    twice for every light cycle. If you've had all the required service done
    by the dealer I think you have a legitimate gripe with Audi.
