I don't know for sure, but I would have thought its the other way around? Ie. it comes on when you turn DSC off? It makes much more sense. But I can tell you from a driver's perspective, I was able to slide my Drexler equipped 135i with ease, where it wasn't so simple previously. I suspect it would be the same with my new car M135i.
