I may have been approaching this question from the wrong angle. if someone went from air suspension to coils and changed the slabs settings on a 2001 d2. When they went back to air suspension, What settings would need to be changed in the slabs settings with a nanocom or hawkeye? thanks

 

you would need to change the program from coil back to sls simply done with a hawkeye, I don't know about the others

 

thanks drowssap. so I shouldn't have to mess with valve openings left and right inlet and outlet It handles all of that on its own? I have already switched from coil to air with nanocom, so, I think i must have a bad compressor?? thanks again

 

check and see if someone unplugged the compressor

 

The compressor had swallowed some water from my last fjording adventure. evidently the intake line wasn't seated properly and the compressor seized and burnt the 30 amp fuse.
I got it pretty much working but now it bleeds off the airbags when the ignition is switched off.
