2002 Mercedes Benz S430 Suspension Air Pump
2002 Mercedes Benz S430 V8 Two Wheel Drive Automatic 91481 miles
What could cause the pump to stay on with the car turned off?
Could be a stuck relay, a leak in the system, a height sensor telling it to stay on.... many different things.Your best bet would probably be to have the suspension system scanned to see if it has stored any fault codes that could eliminate the guess work.
