Before I go any further I do not make a habbit of the following event - However on putting my foot to the floor in my Audi A4on the occasions I need to,once I reach @ 80-85mph the car starts to shudder and the faster I go the more it continues with greater force to the extent it can be quite un-nerving.
I thought originally it could be incorrect tyre pressure or pushing to hard but on driving a diesel with 136K on the clock and the rev not even going above 3,000 that shouldn't be a problem.
So what I wanted to ask is what else could contirbute to this scneario? I have recently had a new clutch and dmf installed but to be honest I doubt if it has anything to do with this as the "problem" only arises at higher speeds.
