[Vwdiesel] Glow Plug Indicator Light

[Gary Bangs]

Bad sensor, or bad connection to sensor. I just had this happen on my 
pickup. My sensor was bad.

My specific symptoms were that the glows were not staying on long 
enough. Disconnected the sensor wire, and they would stay on too 
long(past starting). I took advantage of the situation to upgrade to a 
fast glow system from the older slow glow. Yes, I was a hold out.
