Hi, Ever since getting this car, once warmed up in the Winter for an hour or so and at any time in warmer weather, there is a regular "clunk clunk clunk clunk clunkclunk" upon setting off. Seems to be coming from the rear or centre of the car. Only in first or second up to about 10mph. Is definitely road speed related in it's frequency - at a guess, every rotation of the wheels. Just recently I'm also getting a vibration in the whole car, nothing through the steering like you would with balance/tracking, it's almost as if there are ripples in the road surface. This vibration starts at 50+ MPH and seems to phase in and out, 3 seconds or so of vibe, 3 off, and so on. After reading as much as I can I personally suspect the propshaft but wondered if any peeps on here might have a clue? It's doing me melon in so my next question is, any good specialists in the Wigan area who would know quattro? Ta! Ian.
