That "something" could be as simple as a not warmed up temperature of engine, transmission, TC or maybe even shocks (if they have one) or it could be something more profound. It could be a momentarily higher rotational difference between front and rear tires (let's say your front wheel went over hump or something and wheel sensors detected a millisecond difference in rotational diameter that could potentially affect TC (transfer case). Or maybe even tpms sensors need to initialize before system will give it a green light. It could be hundred of reasons.
We all got that warning at one point or another. I can only tell you 2 things:
1. In general if message goes away after restarting a car and car drives fine (e.g. no rough idle or anything) then it's most probably nothing to worry.
2. Please invest in a descent bmw oriented scanner - error code reader. Otherwise you will never know what error messages you got. Those messages are only iDrive brief warnings, but you need to actually read error codes to know what really happened. Because trust me you will get such messages often and you won't like going for every little thing to a dealer (unless you have lots of free time).

Wow, I really appreciate your extensive answer! And thanks for making me feel ok about that annoying message) I really don't have free time lately and don't want to make an appointment especially if the problem is not that serious.
