I put some 18" wheels on my 2002 S430 that previously had 16" wheels. After a day or so, my airmatic suspension lowered itself and I was wondering if there was something I could do to raise it back myself without going to the dealer. I put the original wheels back on the car hoping it would somehow help, but it didnt. The dash is now displaying the "stop, car is too low" message. Has anyone experienced this problem and know what to do?
