The 2.7T does have an afterrun fan/coolant pump, but the temperature setting 
on the stock thermoswitch is far higher than most cars ever encounter.  A 
few enterprising individuals on Audiworld have discovered a direct swap 
thermoswitch with a much lower temperature setting.  The switch in question 
is from a EuroVan, IIRC.

I've got that switch installed and it works well.
