[Vwdiesel] No glow ....

Do you have the Bentley?  Great glow plug troubleshooting 8.31.  Terminals of 
relay panel should be as follows:
continuity between 87 and bus bar
continuity between terminal T and ground when coolant is below 50°C, open 
when above
there should be voltage between terminal 30 (power from battery) and terminal 
85 (ground)
Terminal 50 should see 12 volts between it and ground when starter is 
cranked.  The recommend disconnecting the fuel stop solenoid (and insulate it from 
ground) for the test.
There should be battery voltage between terminal L (controls glow plug light) 
and terminal 85 when ignition is turned on.
If you do those checks it will isolate where the problem is.
