The other day I notice my glow plug light would not come on and my CEL took its place. The code was 0381. I decided to allow the motor to cool to ambient temperature and tried again this time watching the volt gauge. It started to rise up stopping about at 11v stayed there for about 5 seconds then built up again. I looked on Mr Google for answers and never come up with a definite one. I did a few test of fuses including the glow plug 125a under the fuse box in the engine bay all tested ok. I removed the lower cover on the steering wheel and tested the pink wire ( test light come on). The next step was to rip apart the guage cluster and check the bulb (if possible) but had to come back to work so next set of days off I guess. Any one experience this code and have any suggestions where to look or test before I just start buying parts to throw at it. I could just leave it be as the glow plugs appear to work but I'm not that way.
