Exactly, and below is the response I got from AndroidRobot. Thanks to him it is clear on what to look for both visually and while driving:
"obvious from the valve (not sure if non-MSport one's have this so I guess that's your answer) when I put the car into Sport vs comfort or adaptive. If you look under the car you'll see a wire connected to the valve for control, there's a few posts about people leaving then open instead of iDrive controlling it. "
