All 2 Known Issues
On the 2006-2020 Mercedes-Benz S-Class, the AIRMATIC air suspension compressor burns out from overwork, typically caused by slow leaks in the air springs that force the compressor to run excessively. Compressor failure leaves the vehicle sitting low with a harsh ride.
Common Symptoms
- Vehicle sits very low after being parked
- Compressor noise stops and car does not rise
How to Fix
Replace the air suspension compressor and relay. Inspect all four air springs for leaks before replacing the compressor — a new compressor will fail quickly if the underlying leak is not fixed. Arnott makes a quality aftermarket replacement.

On the 2014-2020 Mercedes-Benz S-Class, the Magic Body Control system uses a stereo camera behind the windshield to scan the road ahead and pre-adjust the suspension. The camera module fails or loses calibration, disabling the road-scanning function and reverting to standard AIRMATIC behavior.
Common Symptoms
- Magic Body Control warning message
- Ride quality degrades to standard suspension mode
How to Fix
Recalibrate the Magic Body Control camera with XENTRY diagnostic tools. If the camera module has failed, replacement runs $1,000-2,000 plus calibration. A windshield replacement also requires recalibration.
