2003 Mercedes-Benz S430 Problems

Airmatic Pump Motors May Fail Due to Sticking Relays

The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off.

2003 Mercedes-Benz S430 Reviews

This is the first MB I've ever owned and its the best car I've owned. I have had several luxury vehicles and am a chauffeur by trade. I have over 250000 miles on it and you would never be able to tell it. Im going to try to get at least 400000 miles same engine/trans.
I have major suspension problems and the trunk looks open all the time.I have had to repair the suspention/ air shocks 3 times at $4,500 a whoop! There should have been a recall on the suspension system it is dangerous and costly. I have broken down 3 times with my car sitting on the street like a lower rider, SHAME ON MERCEDES BENZ
