Hello everyone. In nee of some help. I have a 2003 cl500 that is having suspension issues. for some reason the front suspension is raised all the way. It is very are or stiff. The level control inside the dash wont lower the front suspension. It only works for the rear. I already replaced the front level sensors the tandem pump, and the valve block. I had a friend who works at Mercedes use his star diagnostic tool but couldn't communicate with the ABC Module. He tried the rodeo test but the front end would not move. I also checked all the wires leading to and from the control module looking for corrosion. would love to check the power and ground wires for the module but couldn't find the wire diagrams anywhere. Can anyone point me in the right direction. Has anyone else ever had this problem? Thanks in advance.
