If you go into my other post from a couple of days ago:
....17366-posi-trac-noise...

I just had a discussion with the tech and told him that the night I got my X5 back I got the "BMW SUSPENS LEVEL INACTIVE" message thing, he mentioned that this is related to my un-level system.

FYI. this morning my front passenger side was about 2"-3" lower back to its original problem. I suspect this is related to a elec. fault signal they got but the funny thing was that they said after they re-checked it the fault was gone...

YES the tech said that this is a problem, its going back to the dealer and this will be covered under the CPO ...and YES I'm getting a rental car .

Will keep you posted.
