If under 5 years/80k take it to the dealer, emissions warranty. It might be the control module, mine was out, cost about $60 iirc.

mine has been doing that for about 2 months, starts fine, runs fine, it might take a lil longer to start sometimes though. havent tested the plugs or the 175 amp glow plug fuse, too darn lazy!:D If anyone fixes theirs lemme know what it was.

What I think is funny that my p0380 code comes and goes. It might be on a day off a day or a week either way.
