Sometimes when I'm driving just at threshold of triggering it I notice the dsc light turns on but I don't feel it kick in - if I didn't notice the light I may not have known that dsc is working. One day I may try to add a buzzer or some audible feedback to the dsc light just for fun.
I've noticed that on my 330. The light will come on but you won't feel the throttle being cut or the ABS kicking in. I wonder if its just putting DSC in ready mode? Like...ready to save your bacon mode?
