funny i'm having somewhat or the same problem (01 quattro tt) hence my loging in today..... only my rear wheels dont lock up but when reversing out of my driveway after parking all night my rear brakes squeek and once i start to drive my esp light goes on as if i turned the esp off only i can't reengage it not sure why... i'll keep posted on any advice you might get...

 

I need to quit reading this forum.

I read the forums problems, and only then, do I get them myself.

My new thing is a haldex code that more or less says the clutches are slipping. We'll see how it works out. Wonder how hard it'd be to graft a torsion unit in place.....

 

Haldex Fluid changed with no change. Since the dealer and Audi customer care have completely dismissed this by telling me that the other is responsible for resolving this. I have filed with the BBB and Consumer Affairs. Nevertheless, the problem needs to be solved so I am going to purchase one of the Blue Electronic Haldex Controller Unit's from MJM Autohaus for $744.95 shipped and pop it in with hopes to solve the problem. Trying to keep this updated in the event that anyone comes across a similar problem. Word of advice...Be more aggressive with any repairs while the car is still under warranty.
