4400 miles and engine idiot light on

[MisterScott]

Well, I got up this morning and started my drive to work and the engine idiot light came in the dash. Drove directly to the dealership to see if they could plug it in and diagnose the code. The diesel tech was until noon. He told me unless it is running poorly, then go ahead and drive it. Drove 25 miles to work. All the vitals were normal though though the engine seemed to be running rough. Wierd smell when I turned it off and got out at work. Hopefully it will fire when I want to go home. Turbo is still working, power seemed fine. Oh well... ...

Well three days later the light is still on but the center consol is telling me to get an oil change. This is 1500 miles after I just had it changed. Does the truck actually have a sensor to tell you when to change the oil based on the quality or is it an idiot light reminder?

Do you know what code is being thrown? Put the odometer in the "trip mode" and cycle your key three times on/off without starting and the codes will display.

One of my posts addresses this issue. About overhead errors

Didn't check the code but the check engine light went off. I brought it to the dealer as they had some warranty steering linkage work to do. The change oil message is an idiot light based on the amount and type of driving you do. No sensors to detect oil quality. There is supposedly a TSB that shows how to clear it. I know you all probably know all this already.
