Ride height is controlled by an electronic module. Ride height adjustment is done by computer or one of the shop diag tools.
For home use purposes, in the past I have used ISTA-D on a desktop, but since I haven't yet been able to get it to work on my laptop, I am using INPA for now. (The car is now in Europe and I did not feel like taking a desktop PC with me only for running my E70.)
