Hello After an exchange of the level control unit I can not learn the control position. I have done everything according to instructions , engine runs , doors and trunk to , car on level place , all errors deleted.The programming I have also adapted and both control units have the same part numbers . If I now select via adaptation the channel 01 and the calibration start so the car moves at the front left only about 10mm (from approx. 270mm to 370mm ) then the display value and eg I don’t get to the next steps. If I raise the car over the basic setting it moves only about 10mm the pressure becomes front 9.34bar rear 6.51bar and the compressor then switches off each time. The level readings are then front 129 or 117mm and rear 112 and 119mm the chassis also rises a bit. What is still important, the car was driven for some time with completely lowered chassis (not from And when I picked it up, the air bellows were also extended, so they are movable. The level sensors are free-access and properly mounted, they also provide a clear signal. Someone has experience with the pressures that come in normal operation.
