Im not sure if this is a problem or its just normal, as ive never had a quattro..
But when im full locking the car (left or right) doing a slow turning circle, the back wheels try to grip/spin and has like a bunny hopping effect? It also smells like clutch when it does this...
Heard of this a few times on the forum and think its usually down to the Haldex controller and or bad connections on the connecting plugs due to water ingress.
I have no faults reported and I get a vibrating sensation from the rear when on full lock. No other issues and car seems to work fine, and I have found it is very sensitive to tyre pressures, thats usually my queue to check tyre pressures.

They tailor made it for me as follows:
8 inches long, with a 6mm hole on one end and an 8mm hole the other. Better strap than the OEM. About £4.50 and delivered within a couple of days.
Halfords stock earth straps too, not such good quality and you might have to take whatever length and combination of holes they have. The length is critical.
Hi,
I had exactly the same problem with my TT, 2001, 225 HP (quattro). Googled a lot, found out that is should be something with the haldex... Brought the car to the dealer. They told me my reardifferential was broken, that would be 3000 euro.
I didn't believe that would be the problem, so did not change the diff.
Changed haldex fluid, that didn't help.
Finally went to another dealer: they agreed there was a haldexproblem. Changed the haldex controller (1400 euro), then the problem was gone. It's driving perfect now (it's about a year ago).
So the problem is probably the haldex controller (or maybe the connector of the haldexcontroller?).
You could try to get a used controller from someone who changed the OEM controller to a sporty one (a blue haldex I think).
Most of the time, it comes from the haldex controller. Stepper motor in it is often the source of the problem.
