It started like 2 months ago and it is constant now it does not go off anymore but during diagnosis is see sensor failure.
My car shows me 4matic car rising do not drive.what will do? on 2000 Mercedes-Benz S430
A friend had same problem. It seems like your airmatic suspension is going bad. It's a common problem with these cars than the S500s. May be the suspension air compressor/pump-take to shop for diagnosis(also check REPAIR PAL's answered questions)
