Rear Suspension Very High
I searched the forum for advice on this but did not come across any threads.
This morning on my drive home, I got an airmatic malfunction sign and then noticed the ride was very stiff in the rear. Checked the suspension, and the rear (passenger and driver sides) are very high. Car ride height does not change with pressing the raise/lower button, does not come down when turning off. The front suspension is working fine. Any idea on what I should check, what it most likely is, or does this need to go to the dealer (trying to avoid going to Benz)? FYI both front struts and compressor were changed mid-2016 along with the 40amp fuse. Thanks in advance. |

Were you playing with some lowering links? When I removed mine to replace with the OEM, my rear end did the same thing. MB Came and picked up the car, tech said I installed the rear OEM links upsidedown.

I am having the same problem now. Did you end up resolving yours?

its very odd - that's three people here where its snapped off and they go high - for most people it collapses on the floor
how does it do this ? pure luck it snaps so fast the sensor arm flips 180 degrees and thus by luck goes high ? |

Yes, the rear height sensor’s bracket rusted. After replacing it everything went back to normal.

My guess is that the potentiometers in the sensors were in unfamiliar territory and giving erratic values. Kinda like when you play with the volume knob of a vintage stereo and here a slight crackle when you turn it. That's corrosion and is easily fixed by using Deoxit spray or turning it back and forth quickly several times to get rid of the oxidation. All of this was fixed when I installed new ride height sensors on all 4 corners. |
