I hold the opposite view. Until I can recreate the problem to my own
satisfaction, it doesn't exist.
I have too much experience (a lot of it recent, since I'm becoming known as the
UK's MB engine expert) of people coming to me and describing symptoms that I
can't understand, can't reproduce on my own car, and finally can't even
reproduce on _theirs_.
As I've posted several times - I've thrown the ur-quattro about so much over
the last four years and 80000 miles that I'm _certain_ I would have seen this
hypothesised effect. I haven't. Hopefully, I'll have my car back tomorrow or
Friday, and then I can try some experiments.
If, indeed, there is this exposure with a central torsen differential - where
is the public documentation? Where are the recalls to change percentage
limits? Where are the cautions in the owners' handbooks? A quick search on
Alta Vista reveals that _lots_ of cars use torsens in different ways - but
there's nothing, absolutely nothing, to support some of the wilder theories
of operation posted here.
Dave couldn't find a problem with his RS2 - Roger Galvin didn't find a problem
with his 200TQ. By the weekend, I should know more about the ur-quattro.
