Air Suspension won't revert to stock height
So the back of my e63s is riding pretty high... I brought it to a tech guy I know to get it restored to stock height for some reason the back is reading outside of the parameters and it wont save the calibration even when set to stock height... something about "angles" not being at the right spot. My tech recommended me to a guy who has a special tool to set the car completely leveled to get it to calibrate is that really necessary?
have you done a negative battery terminal pull
