HELP REQUIRED PLEASE:

The other evening I was driving home and the rear suspension started to get more uncomfortable and within a 1/4 mile an Orange vehicle image appeared on the dash with the word MALFUNCTION and when I pulled over the rear suspension had dropped completely.

I would be extremely appreciative of any advice members can provide as to what may of happened, and where should I start looking, at this point I really need to resolve this myself if at all possible, taking the car to Mercedes is not an option.

Any advice would gratefully received


Many Thanks!

Cheapest thing would be a faulty level sensor. IIRC correctly the rear one is poor in its mounting/attachment and a right fiddle to get at. There is only 1 at the rear I’m lead to believe (and 2 at the front)

FYI Arnott do a full conventional suspension kit for the w221 at around £1800 should things start to get costly.
