I had this problem for several months until I found a break in one of the wires where it goes into the connector. I bought two new sensors before I found it. It had the same symptoms- hard starting , stalling ,no power at rpm below 2,000 ,surging acceleration, and hot start roughness.

Betreff: Questions about DigifantII (NVC)

I have a customers 89 Cabriolet that I am trying to troubleshoot.  It is a
Digifant II.  It will start and then immediately die.  It acts like the
engine is flooding out.  One wierd thing that it does is if you heat the
coolant temp sensor (tempII) with a flame the car will run.  However the
temp sensor checks out OK when I check it with a meter, and also at the
wiring harness plug.  I have checked the timing, spark, fuel pressure (seems
a little lower than stock but only 4 psi low) and the engine wiring harness.
Everything seems to be right but the car still won't run.  Any ideas?  Is
there a way to get a code out of the DigifantII ECU?  The car has a code
machine connector by the shifter but I can't get my vag-com software to
communicate with this ECU.  Any advice would be helpful.

Thanks,
Ken Wilford
