The driver seat on '63 plate W204 is increasingly making a clunk when the car is subject to sudden movement/force ie sudden braking to a standstill, going over a large bump, sudden acceleration etc. I can seemingly replicate the clunk by flicking the seat-base height (electrice-adjust) button and the clunk seems to me to be coming from the rear of he seat base. Also makes no difference if I change the seat base height/seat back rake settings.
Any suggestions?
