srs lite on & off
I have been told its the sensor and cost quite a bit to repair. I don't know the extent of my issues since it only activates when my passenger moves a lot. Prior to that, my srs light on dash cluster would always be on. I don't carry passengers often, so I omitted the problem.
Not really that difficult but probably somewhat fiddly
This is a common fault on the w220 from what I have gathered on this and other mb forums
