Volks - I recently made a comment that I didn't think a temperature rise
had anything to do with the Syncro's "magic box" ability to transmit
power to the front wheels, but only that this "secret silicone stuff" VW
patented solidifies when agitated, kinda like my EX.  Finally found the
printout from http://www.volkswagen.org/Syncro

I also recall reading on the List that even a 1/4 turn of "slippage" of
a rear wheel of a Syncro results in the transfer of power to the front
wheels.  If that is so, I do not believe that the temperature of this
SSS (secret silicone stuff) can go from ambient temperature to 212
degrees in that length of time.
