For example, you will get C1324-001 or C1325-001 which mean a communication or fault is present by the solenoid valves in assembly Y53 ( rear axle damping valve unit). It could also be that there is a discontinuity problem with any of the air suspensions components. This will difficult to track down without a scanner. A multimeter is a necessary tool too.
