Hey Guys,
So this morning was nice and brisk. When out to start up the truck and the glow plugs, which normally go out after 8-10 seconds, wouldn't turn off. After about a minute i just turned it on. After which the check engine light was on. Called the stealership to see whats up. They cant fit me in for a 30 second scan until Wednesday.

Also started it up after the engine was hot and the glow plug light came on for five seconds then went out. Normally it doesn't even light up. Any ideas on the problem is? I'd like to prepare myself for another big hit before I go in.
