As title, back of the car, on the passenger side, not got a clue what it is. happens when going over bumps.
Could be coming from the back door area, or the bit of trim where the seat belt goes into on the pillar, i thought it might be even further back then that, round the boot area.
Would the door rubbers make this noise? although the rubbers look good, and dont let any water in?
any thoughts?
