For the self leveling system, it had happened to me in the past by having the rear vehicle totally down due to a bad blown fuse in the back of the vehicle. Once replaced, the entire rear suspension system has been lifted-up completely about: 30mtes. And once in a while, if I don't start my vehicle for 3days, the rear seems to go lower slightly N'till the next start-up.

Specially now with the "sloppy road outhere with snow melting down as you mentioned, everytime I park my X5 on top somewhere by having one of my rear tires up/not level to the ground, next time I start my car, it will cause the self level system automatically comes on. But I'm really not worry about it because I found a way to make it disappear in my dashboard by: backing-up the vehicle about 6 feet and move forward after that. If it doesn't go away, turn the engine off and start the car back on, the (Self level suspension system should go away)

If it doesn't go away by doing so, than you might have some serious self suspension problem or the sensors gone bad. Otherwise this only happend to me when I park my X5 with the rear not level.
