My suggestion would be to confirm the diagnosis first.....>>
It may be something as simple as a bad controller (relatively common) as opposed to a completely malfunctioning Haldex (rare). Find someone with a VAG-Com and run the electrical diagnostics and see what (if any) codes you get. Used controllers can be had here relatively cheaply...Unfortunately the entire Haldex mechanical unit is sold as a subassembly that includes the differential and is, indeed, expensive..
Something as simple as a bad brake light switch (really common and a $10 fix) will completely disable the haldex.<ul><li><a href="https://forums.audiworld.com/tt/msgs/1452481.phtml">Run these checks yourself to confirm....</a></li></ul>

Re: Did they tell you "what" was fried? or Why? IF it was just a controller, that's a cheap fix!
I've spoke to the Mechanic, he basically said, based on what you are telling me, its most likely the Haledex unit...I guess I need to get somebody trustworthy where they don't just want to "sell" me a new Haledex, instead of a less expensive controller.
It does make a noise, similar to a CV Joint gone bad when you turn. On a minimun turning circle, wheels tend to lock themselves almost....car will still move, but it takes a bit more power to get it going.
