Subject: Wire harness for PASMvalve unit Information: The wire harness for the PASM valve unit is not routed correctly in the area around the heat protection panels for the valve unit on the affected vehicles. Due to relative movements while driving and if significant amounts of dirt get in, this can cause chafing on the wire harness and as a result, faults can be entered in the fault memory and the warning "Chassis system fault" may be displayed in the instrument cluster. As a result, the vehicle level can no longer be set.
