Came off a roundabout the other day in the wet, back end let go, I caught it, no problem. Except that the ESP was turned on and nothing happened when I lost grip - no cutting of power, no light on dashboard.
Got it to a gravel car park to see what would happen if I floored it and the rears lit up - ESP did nothing, gravel all over the place.
Tried turning it on/off till blue in the face but I cannot make it work.
Any ideas?
