I have a 4.4i.

Also, when I press the Check Button, the warning doesn't appear? Could it be that it just inactivated that one time when I parked and is working again?

I'm confused because I also get "BMW Assist Inactive" every 5th or 6th time I start the car, and I know it's not active. It doesn't display EVERY time I start the car, and it doesn't display in the list of errors when I push the dash button. So, following the behavior of BMW Assist Inactive (appearing every so often when I know it's 100% inactive), is my Self Leveling 100% inactive and the computer is not telling me everytime I start the car, or was this just a one time fluke that occurred when I parked the car?

To make matters worse, the Check Side Lights also came on later in the day...my right blinker was flashing really fast in the dash, so I assumed I had a burnt out bulb. However, no bulbs were burnt out. I played with the blinkers and the hazards checking everything...no burnt out bulb. THEN, the "Check Side Lights" warning went away! WTF?
