The vehicle has a Check Control message "Self-leveling suspension failed/malfunctioning" displayed.
At least one of the following fault codes is stored, and is currently present in the EHC control unit:

CAUSE
Fault in the compressor unit
CORRECTION
If one or a combination of these faults is stored, replace the compressor unit only, using P/N 37 20 6 792 855). It is not necessary to replace the
entire air supply unit.
For the compressor unit replacement instructions, refer to REP 37 22 750.
[NEW] Note:
The replacement compressor has several technical improvements, which may result in a distinct audible difference when running compared to the
original compressor. This "raspier" sound is a normal characteristic of the replacement compressor.
