Just taken the S3 for 60 mile round trip for a job interview and heard and felt the most annoyig vibration Ive ever experienced in a car. Now the car has recently been returned to me from the Audi bodyshop and it certainly wasnt there when it was delivered to them. In any gear when decelerating....foot off the throttle, there is a real bad vibration that can be felt throught the whole car and a loud rumbling noise. Now if you knock it out of gear the noise stops straight away and when put back in gear it returns until the car is slow enough and it stops. Now if I put my foot back on the throttle slightly the vibraton stops......its only when there is no throttle input......any ideas. Im waiting for the garage to get back to me as I dont really wanna drive her if its a serious issue.....ie gearbox. Is it just coincidence that its been in the oven at the bodyshop??? Something dried out possibly.
