skiboats, I would imagine you'd have killed someone by now if you didn't have that warranty.

Casey, it will be more expensive to replace all 4 obviously, but it can be done. The OBC just needs to be told that there is no air suspension module and to stop looking for it. Then you just rip everything out and put in standard struts/springs. Not all E53 have air suspension. As far as I know, there is no limitation that you would be unable to remove it. Search the forum for it. I know I've seen posts of people going to standard struts/springs.
