Glow plug P codes

ECU

2006 T1n 118 Sprinter
This winter I have been working on a project close to home. So I drive only a few blocks in the early morning.
I throw P codes if I shut the motor off, when I restart later. I get P0380 and P0674. Sometimes it is P0673.
These are all glow plug related. I do wait to start.
If I let the rig idle and warm up when I arrive at the job site, things go fine.
What could be doing this?

Aqua Vic ran the codes up on his threads but not the sequence to each specific code.
If no one answers by night fall I'll run them up.

The P0380 is apparently one of those codes which has multiple identities on the list. I'd figure it's related to glow plugs until you test and find something different.

You may have problems with #3 and $4 glow plug circuit, or maybe not. The glow plug fault identity design in T1N's is notoriously inaccurate. It needs to be verified using Doktor A's jumper wire and 20 amp fuse test method among other test procedures.

Maybe once the engine is warm you don't get codes because the glow plugs aren't called upon to work?

Hope this does some good. vic

I only get the codes when stoping it when very cold. Not cold of air, but cold of engine. Running for less than 10 minutes and shutting off.
I did have a low battery at 10.5 volts, 9 when cranking, when it happened the first time. So I did think it was a battery issue. But it popped up again this week when I forgot and shut off the engine.
