That is all great if the code it throws still allows you to start the
car.

In my case the code was for the number one glow plug. Doesn't affect starting, unless it gets a lot
colder!

The code just gets me in the ball park. It could be a bad glow plug, the wire to the plug, the glow
plug module, the wires to the module...only God knows where it may stop. I may have found a
trustworthy repairman, though. Not the dealer.

Since all of the glow plugs come on at the same time you could cut the
problem in half by swapping glow plug wires.
You could also check it with a meter and compare a good one to the bad
one.
I might just throw a new glow plug at it without doing any more
diagnosis. Worst case is you have a good, spare glow plug.

The code certainly gets you right down on the problem tho.

I disagree, having seen how a Mass Air Flow Sensor code can mean the
screw on the Ignition Module under the Distributor Cap was loose.. Or a
Crank Angle Sensor (or something or another) that was disrupted by a
screw holding a body part on, installed at the factory that finally wore
through a couple years later... oh, it was a rear deck lid. You may
think the code gets you there, but to me trusting FRED (****ing
ridiculous emissions device) is like a baby crying... It may be making a
lot of noise but it doesn't know if it's hungry, or just has to crap a
diaper load
