I am wondering the same thing for the 2.1L heated OXS.  I have a VW sensor 
with unknown miles of use with which the van drives well.  On the other hand, 
I have an aftermarket Bosch (intended for a Ford, I believe) with which the 
van has a hunting idle.  The VW OXS has a cold heater resistance of about 5KΩ 
while the aftermarket one reads about 12KΩ.  Now, is the VW OXS still good or 
not?  As I once asked before, does anyone know for certain what the cold 
heater resistance is of a new, VW-issue, 2.1L OXS?
