I've been getting that code also. It is a generic code, meaning it could be the def system not cleaning the DPf we'll enough, clean your def injector, look into it when you remove it. Could be the Nox sensor not reading correctly, could be an exhaust leak. Have to go step by step to rule each thing out. I have a new def injector and my DPF looks good. I have to check the exhaust because the studs broke and I drilled them out and used red silicone, but I bought a new gasket I have to install. I usually clear the code and it might not come back on for 300 miles. I'm going to check those things again and then see if I find anything. If not I'll take it to the dealership cause it's still under the emmission warranty. Good luck

I've been having the same symptoms, what did you end up finding. I also used red silicone so I'm going to install the gasket first. Injector only has about 3k miles, so I don't think it's that. Code usually comes on after warm up when the truck sits for at couple weeks. Otherwise it doesn't come on if I drive it everyday. I think it's the nox sensor, but who knows
