Hi, was it intermittent? i.e. did the noise go away after a few miles once the car has warmed up? I have a very similar
problem, been in the dealers 3 times in the last 12 months and it NEVER makes the noise
even when kept overnight. It is noticible on rough/uneven/bumpy ground. My car is 07 with 22K but this noise has been present on and off from 9K.
Any advice will be much appreciated!
