BMW 93076A DTC help

1
Good day friends, I was ask to diagnose a 2012 BMW 535i with N55 engine. The customer complaint was that the rear of the car suddenly lowered and after bringing the car to a dealer to fix the problem who he said replaced a relay and then thinking he had a successful repair, only for the car to lower again on his way home and has not risen since. After scanning the car i got 4 codes  8020E8, 480DB0, 93076B intermittent and 93076A as the permanent one. I proceed to clear the codes and ended up with the permanent one coming back. I tried accessing the service manual but with no luck concerning the codes. Anyone with experience about the problem to assist please. Thanks in advance

If it is lowering then you have a leak or faulty valve at the pump and also failure of system to detect loss of height so it is not pumping it back up to compensate. What diagnostic software do you have? Start by checking fuses and confirm nothing is unplugged then we move on from there.
