Sorry if this has been asked before, searched and couldn't find a straightforward answer: if you have the factory PSE, is it supposed to automatically engage when you depress the Sport Mode button?

 

Yes.

 

Thanks, that's what I thought. My dealer is telling me the opposite. When I picked up my GTS (Sports Chrono, PDK, and PSE) it was working that way and has now stopped. The PSE works normally when using the PSE button, it just doesn't engage/light up with the Sport Mode button.
