My 1994 C180 has a door rattle recently possibly due to loose locking cable from a door panel repair work done last November. May open up to sort this out soon. The other noise is the squeak from the seatbelt retracting assembly in the door pillar when I move around in my seat. Recent squeaks coming from the rear sus. possibly due to shocks reaching expiry date(some liquid looking leak visible on the pistons). This squeak comes only when I run over the road speed bumps, otherwise they are silent.
