Grounds and clean connections are the key. I have added extra body to
engine ground wires, as well as  wires from the alternator and the AFM
casting.  All the connections are cleaned and assembled with di-electric
grease.   I was told by several sources, including the local VW dealer
(wouldn't you think he would want to sell me a $100 harness "fix"?) that
the harness is a Digifant only item.  Something about digital versus analog
and the internal connections are different....   I  would also bet 99% of
the Temp II fixes are a result of the cleaned up connections  or the lack
of  corrosion on the internal part of the sensor.
