(Rear?) Suspension Knock on S3

[gdwood]

Has anyone experienced this? It's like a muffled rumble that sometimes escalates into a brief knocking sound. It's best heard on a flat level road whilst cruising at low speed in 5/6 gear. Dealer said it was a loose exhaust heat shield, but adjusting it made no difference.

I reckon it's something to do with the rear suspension (dodgy shock absorber, perhaps?), but I'm stumped, as the dealer can't find anything wrong.

Suggestions please? /ubbthreads/images/graemlins/confused.gif
