 DTC 1583 (leak in the system recognized).
 DTC 1770 (sender for compressor temperature of self-leveling control G290).
 DTC 1772 (signal cable of pressure sender for self-leveling control G291).
 DTC 2645 (valves for self-leveling control).

Technical Background
Because of poor performance or failure of the compressor for air suspension, the vehicle position cannot be
adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the
warning light. Drivability is not affected.
Production Solution
Not applicable.

4. Open the relay and assess the
contacts. Compare them with the
contacts of Figures 1 to 3.
Is the wear is similar, or are there burn
marks in the housing?
If the relay resembles Figures 1 to 3,
replace the compressor and relay J403
for the self-leveling system.

indication of permanent operation of the
compressor (Figure 4).
Replace the compressor and relay J403
for the self-leveling system.
Figure 4. Overheated strand.
6. If the contacts resemble those in Figure
5 and the compressor has a working
noise similar to a comparable vehicle,
replace only the opened relay J403 for
the self-leveling system.
