R36 Haldex System Question?

[Gipper]

Guys

Have a question regarding the Haldex AWD System in the R36 Passat.
I understand that the Passat is essentially a 2WD until the haldex system detects the front wheels sllipping. It then sends power to the rear wheels via the Haldex clutch.

What I was wondering though is how long does it remain in AWD mode (without the wheels slipping) until the Haldex clutch disengages and it goes back to 2wd?

Any ideas?

Goes back to FWD on a sliding torque scale (see's a drop in transmitted torque) it's all in the program depending on the type you have.
