I got the same message last night when I started my x3 at work. When I got home the warning light went out.
I haven't had a chance to check yet but I suspect one of the bulbs behind the led tail lights on the tailgate has worked loose. I will look at it this weekend. My first thought was it was how cold it was outside yesterday here in NorCal, but I think super is right.
