Another ABC problem, car is a 2003 CL55 AMG. Suspension works fine dynamically, is level, and no signs of leaks. Problem is that it will not react to ABC height change nor lowering links i installed. Height stays at what I assume is max position showing about 1.5 inches from wheelwell to tire OD.

Any ideas?

You could try disconnecting the battery. Much like rebooting a computer.
Otherwise not having the proper scanner there's not much you can do without info.
