It's activation thresholds points are significantly raised...but it's not totally off.


VDC off isn't really off

 

that why you should get AWD for winter



I love S4 in the winter, specially when it cold, and my turbo love cold climate

 

I've noticed some cars it is, some car's it isn't. I know 100% for a fact when I hit my VDC off button, it is OFF. I have no idea why in my car it is, but in others it isn't. My dads M35 still has SLIP on with it off, and so does GeoBau's 03.5 Sedan. I autocross and track my car and beat on it daily, I know it is off when it is off. I think 06+ coupes have it off when you press the button.
