Reason for block
Complaint:
Vehicle sinks at right rear wheel after standing for a long time (longer than one day).
Attachments
Cause:
Score mark in pressure line for right rear air suspension strut leads to gradual air loss. Compressed air escapes at connector of pressure line on valve
unit or at connector of air suspension strut. (See picture "Anschlussstueck.jpg" in attachment).
Remedy:
Check connector of pressure line on valve block and connector at suspension strut for leaks using leak detector spray. As the score mark in the
pressure line runs along its entire length, a sectional repair will not be successful. If leaks are detected at one of the two connectors of the pressure
line, the entire pressure line from the valve block to the right rear air suspension strut must be replaced.
