And if you want to reach them, a limited-traffic newsgroup like this
one isn't the answer. Take an ad out in a newspaper. Posting your sob
story every week won't do anything.
Bottom-line: the folks who care have read your post. Please don't
post the same story again. Post a link to it next time.
BTW, I have never seen any advertisements that claim that one side or
the other of the car will get power if the other slips. Quattro is a
front/rear thing, not a side/side thing.
My quattro has a vacuum-actuated diff lock engaged with an electric
switch. Works great, and self-disengages on speeds above 10mph or on
turns below a certain radius.

Is that how it is on all quattros or just model years. The closest I
have gotten to that situation is my 97 a6q. Hard acceleation with one
side on gravel. It went go-go. No wheel spinning.

I had always understood that quattro limits front/rear wheel speed
differentials. Only the manually locking diffs would limit side/side
wheel speed differentials. Whether through a vacuum system like my
car, or a switch like the 4000/5000 series. (urQuattro too, right?)

The electronic differential lock (EDL) permits smooth, comfortable starts on
road surfaces that do not have a uniform coefficient of friction. If a wheel
starts to spin, EDL brakes it as necessary so that power is transmitted to
the wheel with the better traction. EDL reduces tire wear and works up to
about. 40 km/h (quattroŽ: up to about 80 km/h). EDL is part of the
electronic stabilization program (ESP) and the traction control (ASR).
This is the advert. Notice the piece "If a wheel starts to spin, EDL brakes
it AS NECESSARY so that power is transmitted to the wheel with THE BETTER
TRACTION". This is totally false as in my scenario, the two wheels with the
better traction where the ones that did even get any power at all, least of
all the NECESSARY amount transferred from the brake actuation.
