Detroit 1-box filter cleaning notification (dash light, error code?)

I don't know if that particular model says if replacement is required or not but engine's will derate for many different issues with the emission system. Could be that there was a fault with something on that company truck and continuing to drive it eventually damaged the aftertreatment system.

 

They usually need to be baked clean the DPF at about 400,000 miles. I think only the news 2019 truck has display showing how full the DPF is. My 2017 don't show that.

 

There is an ash accumulator reading, you have to us a shop pc to read it. When it comes time, your truck will throw a DPF ash filter full code (or some other verbiage close). And you will get a check engine light, and it will get progressively worse derates until you get them cleaned. Depends on what you do with your truck. I’ve seen the filters need cleaned @ 240k miles. This can be done for as little as $600 if you do the labor yourself
The company truck had the entire one box changed because it was drive for 40k miles with an egr code and it either pushed a DOC or coated an SCR. That was probably a $15000 repair.
You can ask to check the DPF Ash accumulator at you next service. It’ll be a percentage. You mentioned you’ve lost some power since it was new??? You said you have 160k on this one, have you had the over head ran yet?

 

The Ash accumulator reading is correct if new or reman DPFs are installed and ash accumulator was reset. If engine works properly filters will last about 370-400k miles. If your filters were cleaned before max they will go is about 250-280k miles. Your filters will get clogged but you will not get Dirty/Clogged Filter fault code and Ash accumulator will show 65-75%. You will think its ok and not a time to change/clean them. One beautiful day you will have DOC High pressure code and sometimes DPF Outlet High Temp code. My suggestion is not to clean DPFs. Detroit has reman exchange program for DPfs . Each of them is about $800 exchange. They will go like new ones ~400k miles.

 

Depending on application, the ash accumulator can show full and DPF filter need changed as low as 240,000 miles, I’ve seen it. In the fleet I take care of, we have high Idle /load time, our average filter life is 260,000. A soley “over the road” truck probably gets 400,000, but I haven’t seen it in my fleet. As for the doc pressure and DPF temp codes, I’ve found that they come from driver habits. The situation we found was from a farmer we hired that drove it like a farm truck. He skipped gears, lugged it, and didn’t know what a Jake Brake was. Come to find out, Jaking down helps keep the doc’s clean. And driving it correctly is a requirement now!!!

DOC is the diesel oxidation catalyst. Its job is to remove hydrocarbons from the exhaust. Its reaction also generates heat for the DPF to aid regeneration. Fuel is often used to dose the DOC to help it generate high heat.
