Clear it and see if it comes back I've had 1 before but on #4. I knew something was screwy when my wait to start light didn't go off.

How cold does it have to get before you have to wait for the glow plugs to do there thing? I drive to places in the high-desert that can get down into the higher 20's at night .

On a morning, at that cold, you should at least see if for ~2-3 seconds.

During the day on a 60+ climate, my light never comes on.

I always see mine for at least 1 second. During the winter anywhere from about 3-8 seconds.
