Air Suspension Fault and Adaptive light issue

[Papereyes]

Hey all

Just turned on the car and all of a sudden I got an Adaptive Light Issue and Suspension Fault followed by Air suspension fault.

Ran OBD11 and it gave a few error codes:

Any suggestions? I've tried to clear control faults on odb11 but the errors still remain.

Might need to take it to diagnostics, but thought I would give everyone a shout if there are any ideas.

I did hear the compressor running quite loud a few times post engine shut off (but thought this was aircon rather than air suspension).

Thoughts welcome.

Cheers

The left height sensor is faulty, what is the VIN?

If the wiring looks good, replace the level sensor 4M0 941 285 D which is £192.60, there are some good aftermarket versions such as the Vemo V10-72-0218 and there are some Chinese Replacement Auto Parts.

Thanks crasher, turns out some rodent had chewed through the cable. Garage fixed it so luckily didn't need to change the cable. Bloody annoying though!
