Mfactofy has an lsd for the haldex unit, here's the link: http://store.teammfactory.com/a3-tt-02m-quattro-6mt-helical-lsd-rear/I hear you, my suggestion for the LSD was mostly because it's a lot more cost effective for the average person to have us install to their car and get significantly more out of the power that they're making. The best possible setup IMHO is to have both a front LSD and AWD. I have a Peloquins high torque LSD installed on my CC and I love that thing. When coupled with the solid SuperPro 26mm rear sway bar I have on it now and the extra 5" of wheelbase that you get with the CC, you can really start to control the rotation of the rear of the car.
The only downside right now is that I can't do any burnouts unless its slick outside due to all the traction (I really need to get around to slapping a big turbo on it or going with my dumbass 2.5L swap idea). I also wish someone would finally step up and get a proper rear diff made for Gen 4 Haldex! I know I've seen the threads on getting them made, but so far no one has actually come through.
