I'm sorry, but what is "flipped the actuator" mean? I've still been having this issue come and go and I'm on my last string w/ it. I've got a BMW laptop so that I can run codes, but I've truly got no clue how to use it to it's fullest potential. At this point I'd like to advice from someone who's actually been fully BMW trained.

On an unrelated note, on my last soaking wet highway 8hr roadtrip, not only am I getting TFS error messages, but now the SLS code is coming up and the back end of the truck insists on raising itself fully. I've been able to use the laptop to lower it down all the way, erase and existing and pending codes, but once I cycle the engine or start driving and take a corner, it's right back again. Searching for a replacement SLS sensor has gotten me a few hits, but I'd like to know if there is a simpler fix beforehand, ie similar to the ABS wheel speed sensor cleaning to fix random issues.
