[Vwdiesel] TDI non-start

[S. Shourds]

I'm finding that most of the time I'm spending on this problem are 
perusing the manual and the archives at TDIClub.com instead of in the 
driveway with a wrench. 

I've established that there is some kind of ECM or other electrical 
problem, most likely.  Neither the check engine or glow plug lights come 
on when the key is turned to the "on" position.  This apparently 
indicates that there is no power to the ECM or that the ECM is hosed. 

Not that I know why that would be.  The 109 relay is brand new.  There 
has been some other weirdness lately.  Some of the adaptations I had 
made w/ VAG-COM have reset themselves to factory settings a couple of 
times and I've had to re-adjust the idle fueling.
