The Haldex system has been used by the Volkswagen group for a couple of years already in all their 4wd cars with TRANSVERSE engine. That said, the only Audi that has the Haldex system is the A3 which I don't think is imported to the US.
In the Audi A4 (at leats the old model) and the bigger Audis and in the VW Passat the system used is the "original" Quattro with a Torsen differential.
Come to think of it, the Audi TT has the Haldex system.

The difference is that the Torsen-Quattro system always splits power 50/50 whereas the haldex only distributes power to the rear wheels if needed. Quite like the old system Volvo used. The difference is that the Haldex system is electronically controlled and MUCH faster than the viscious coupling system.

I say you have nothing to fear in terms of reliability when it comes to Haldex. It's a good system that's tried and tested.
