Check Engine light

I have a 2008 f-350 powerstroke check engine light came on, its on solid not blinking. only has 15,000 miles on it you think it is safe to drive not sure what to do, been on for 24 hours now. I know you have to take to dealer to get the codes but will that be covered by warranty to have it checked.

As long as its not blinking or the truck isn't in limp mode, you should be don't have a code reader do you? You can take it to the local Autozone and they should be able to pull the code for you so you can at least get an idea of what it is

I bought my truck used with 80,000 miles on it and the "yellow" engine light stayed on more than it was off for around 5,000 miles. I read the manuel and it said 1 of 4 things can cause this:
Bad fuel
run out of fuel
water in electrical system
I forgot the 4th reason
I always assumed it was bad fuel. The light would stay on for a few days (BTW, the truck ran fine) until I filled up somewhere else. It got to where I didnt even pay the light any attention. After about 5k, I deleted the DPF/cats and plugged in the SCT tuner. I have yet to see the light again. I have had it deleted for over 3k miles now. Now I am thinking that I had a clogged up/malfunctioning DPF.
Your truck has alot less miles then mine but who knows?? Could be the DPF??
Good luck man!!!
