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?

I believe it is also engaged when you are launching from a standstill.

Can't help on how long it stays in AWD mode though.
