[Vwdiesel] No glow ....

[Derek]

Nope no AC and there is no temp sensor on the head itself.  I have two and 
they are located in the flange that attaches to the cylinder head ( slightly 
to the right of the injector lines )

Anyway, ETKA told me what sensor was for the GP's.  I confirmed this with my 
VW mechanic and got one today.  Didn't help anything at all ...  guess it 
must be the module.  As far as locating it goes, it would appear to be well 
hidden.  I traced some of the wires and they went under the battery tray.  I 
re-located the line and it appears to go into the firewall.  My guess is it 
is somewhere behind the dash, but that's a moot point.  I don't know what 
one of these are worth, but its more than likely more than I want to spend.
