The function of this switch is to lock the rear differential so that both
wheel spin at the same speed. ONLY DO THIS on dirt roads, mud, rain, and
snow. When the switch is locked, and you go around a corner (with the inside
wheels spinning slower than the outside ones) you can damage you diff. The
system automatically disengages at 15mph. This feature is handy if you have
ever had the problem where you get your wheels stuck in something, and the
engine power always goes to the wheels that is easier to spin (the one in
mud!). Here you just lock the diff,and shoot on out of the mud or snow drift.
There are lots of guys on the list who know MUCH more about it's function than
I do, I had a Quattro for 2 years here in Florida and never had to use it.
As for why the switch was dropped, I believe that was because it became
automatic, the car would know what wheel is stuck....I think, not sure on that
