Mine came on this morning but also read "4x4 Inactive" on the cluster. After a restart, the light went away. Things like this occur because of voltage. As of now, my voltage regulator is on its way out. But for you, the story is different.

TwinsPoppa had the same problem a few months ago, luckily he has a GT-1 and it spelled out SAS. So he DIY'd it himself. You got to spend a few bucks to get the fault back, but atleast you can stop guessing.

I think you're right on this one TwinTurboGTR
Good luck with your light. Mine started like that as well. Would come on then go off after driving. Or just be off the next time we drove it. Happened for about a week or 2 of intense snow driving, then decided it wanted to stay on forever.

I'm going to see what my BMW indi says. Heading out of town so it might not happen for a week or 2..
