This came up on the dash information center. It said check exhaust filter now.Took it to the shop about a month later and a few parts it can to be the intake manifold gasket had blown. 07 3500 just though I would throw this out there. Glad it was a company truck. You would think chevy would have know what this was but they sent it to a diesel shop. I did fell to say it was a diesel.

dont they have a "cleanout" deal like the semis have where it runs under load (with timing) and heats the exhaust to clean that out? i know those you have to do every so often if you lug the engine alot and cause more soot buildup in it.

that does seem like a long time, i guess it depends on where you took it and how fast they work.
i dont know if smaller pickup engines have the deal, i think they call it filter regenerate or some crap, but on the semi trucks you activate it when the light comes on, it revs to about 2300 rpm, pulls the fuel timing back and runs the fan to help load the engine and heat the exhaust, and it burns all the collected crap out of it. burning it off a second time and wasting 15 minutes worth of fuel apparently is supposed to produce less emissions.
