As stability control evolves, mfr's are providing more DSC modes for owners to choose. But on my 540, there appears to be a choice of either DSC on/DSC off.
1) In this application, when DSC is off, is just the traction control disabled or are both traction and stability control turned off?2) On some earlier cars, it is possible for an owner to reduce intervention by holding the DSC button for an extended period. I've tried this (holding DSC button for 10+ sec) but don't sense any difference. Is there a different sequence I need to use or is it simply a binary feature (on/off - nothing else)
