03 270 Noise / loose cabling or wiring - Surrey59
M Benz 270CDI estate 2003.
On driving over rough surfaces or particularly one front wheel hitting a speed bump there is a rattling / whip cracking sound from what seems to be behind the dashboard in the bulk head area. Nothing seems loose in the engine bay. It has gradually got worse. Nothing found or solved in routine servicing - one specialist talked of having it in for a day or 2 to examine it. Any ideas or experience of this gratefully received

I changed the radiator because of fault noted in HJ's text re leaking into gearbox oil matrix. Should I have the auto gearbox fluid checked or changed ?

My dad's C270CDI Avantgarde SE estate (also 2003) on 17" 5-spoke wheels snapped a coil spring a couple of months ago, it could be worth getting this checked out as it only made a rattling noise under extreme load (one wheel hitting a speed cushion, pothole etc) and it made no difference to the way the car drove. The snapped spring was only picked up in the MoT test.

The replacement pair of springs were not as expensive as you'd expect (around £55ea IIRC)

C class w203 are renowed for braking front springs I noticed in the paperwork of mine two front springs have been replaced because they were found to be broken during an MOT.
