Quattro IV ...???

no, it is working as designed.  the behaviour is caused by the torsen -
which is locked when the torque difference between the front and rear
drive-shafts is less than the "bias ratio".  when this torque difference is
exceeded, the diff unlocks and this behaviour disappears.

"When she turns a sharp corner - slowly - something
feels like it's rubbing
or grinding. That never happened on my 1St V* and is
not happening on my
current V8 - both '90s. It almost feels like an
American 4WD system, say on
an Explorer, when you have the 4WD on, on dry
pavement - but not quite as
dramatic. What's up with that? Is something wrong?
Should I worry? Should I
have it checked? Or is that just how they now feel
under those maneuvers?"


My A4 does that too.  At slow speeds from a stop, then
do a sharp turn?  I believe it is the torsen rear
differetial making that noise.  Mine has done that
fromm day 1 so I would not be worried
