Time to start digging into an intermittent problem I've had for a while as it seems to be getting more frequent and has now twice caused the car to drop to its guts off-road.
After a few minutes of driving with vehicle raised (either llams settings or factory off road), the orange suspension fault light appears. Fault codes from most recent time were:
C1A06-78 (28) Rear right height sensor - Mechanical failure - alignment or adjustment is incorrect
C1130-7A (6C) Air spring air supply - Mechanical failure - fluid leak or seal failure
The time it occured the weekend before, fault codes were:
C112F-72 (28) Air spring valve - Mechanical failure - actuator is stuck open
C1130-66 (28) Air spring air supply - Algorithm based failure - signal has too many transitions/events
Most of the time, a restart will clear the code and there are no dramas. Twice now though whilst continuing to drive it has then escalated to a 'red' fault, limited top speed and dropped the car to the bumpstops - not ideal on a rocky offroad track. A restart then clears the fault and the vehicle raises - albeit slowly. I have no other dramas with the compressor - it was upgraded to a AMK from original about 2 years ago. It doesn't droop when parked for any period of time.
The fault codes only occur with the vehicle in a raised height. Running standard height or lower (using llams) does not produce any errors.
Any ideas where i should start looking?
