With any EHCII faults you need to physically hook the car up to DIS/GT1 and do a readout of the faults in the module, it could be something as silly as clearing the module and running a ride height recalibration.

Are you holding air in all 4 corners?

To rule out alternator under/over voltage causing random errors, run the OBC test 9 when the car is running to see what kind of voltage you are putting out.
