I get an on-and-off "Airmatic, car too low!" warning whenever I have passengers sitting at the back of the car. The warning will appear for a few minutes, then go away. When I only have a passenger in the front seat, this warning does not appear. I took it to the local mechanics but he did not find specific problem for the first try. I did notice that both of the back tires seem to be closer to the car housing than the front, though there are still some space between the tires and the car housing.

I found a link with repair instructions. But it looks to be complicated for me. Can someone help me narrowing down the possible cause of the issue instead of sending the car to dealer for super expensive fix? Much appreciated.

VIN? Reason I ask want to establish if this is a 220, 221, 222, or 223. If, in fact, 223 should be covered by warranty but your comment “took it to the local mechanic” leads me to believe otherwise.

 

It is a 2002 S500.

 

220 should be posting here: https://mbworld.org/forums/s-class-w220-16/

 

Ok. I will post it there.

One possibility - The Airmatic system controls the rear ride height using a single height sensor mounted to the approximate center of the rear axle, with linkage to the rear antisway bar. It is not unusual for the linkage to get bent or rusty and cause the ride height to change.

 

I pressed the button to raise the car. It light up the button and showed "Airmatic is rising". However, the car did not raise up and stayed at the same height while continuing to show "Airmatic is rising" on the dashboard.

 

Is the level/height sensor located in the front or back? I saw a Youtube video replacing the front level sensor. Is there a rear one as well?
