From past experience with leveling air suspensions (over road trucks) I find it somewhat hard to believe when dealer is telling me that they had to re-calibrate my actuator after a questionable air bag replacement. I thought these to be mechanical devices only with no internal calibration?
Had an issue with passenger rear sitting 5.6 centimeters lower that driver side and they replaced airbag ($$$) and took it home only to have the same issue. Latest is "we are sorry, we did not calibrate after the new airbag".
