As I said "If the TC is off and the ESP senses the car getting out of shape (lateral movement or any real yaw angle) the system will re-engage the TC." What you sense as an ABS interaction is in fact the ESP (stability control) doing just that, stopping the car from drifting.

And as I said "the only way to get real burnout style wheel spin is to disconnect the F3 50 A fuse (or wire going to the fuse) in the small fuse box on the right side under the hood. Doing that will fully disable the TC and the ESP systems." It will also disable the brake-lights. Beware.
