I was driving my GMC Duramax 2002 today and got the service engine light message. The truck has about 86,000 miles on it. The diagnostic code is 380 and indicates it's something with the glow plugs circuit. Has anyone else experienced this and what to do if you did?

well seeing that this is a diesel discussion for mostly mercedes i doubt anyone will know. you could call autozone and they will be able to look it up in the computer. why did you make two posts about this? please delete one of them

Judging that its got 86,000 on it, possibly original plugs....and relay etc...I'll bet that one or more glow plugs burned out, there ARE 8 of them... So its likely. If they are original they should probably be changed anyways. I'll bet just changing all the plugs will solve the problem.
