Hey guys, looking for some technical advice, it seems to me that the conditions for the ESP/Traction Control and the Haldex to engage actually contradict each other.

i.e For the Haldex system to engage, it must detect the front wheels slipping in order to transfer some power to the rear wheels. However as soon as the front wheels would have slipped, the ESP would have also detected this and limited power/applied the brakes to the relevant wheel in order to control the car. Thus the haldex system would be disengaged before the driver was able to even experience the benefit of having 4 wheel drive?

It seems very contradictory, I'm struggling to understand the relationship between the two systems. Is there a threshold between the two to allow precedence of the Haldex engagement before the ESP/ASR systems cut it off?

Or is it better to turn the ESP/ASR systems off if the benefit of having 4 wheel drive is actually desired?

Any help greatly appreciated!! :-)
