Hi Guys

I have a 2006 Mercedes-Benz ML500 with an AIRmatic issue.

A previous garage has fitted a replacement compressor and a left rear height sensor. The car came into my customers garage with uneven rear heights. The garage used the switch on the dash to raise the car and after that it would not come down and was stuck on full height.

Using Autologic I managed to automatically lower the vehicle to its programmed height but when I try to save the calibration the tool tells me the calibration has failed. I tried it with the Autel tool with the same results.

The programmed heights show -30mm. I tried to set the heights to 0mm and it still fails.

Is there some prerequisite set up that I am failing to do that the scan tool and WIS doesn't tell me?
