DPF Showing 83 to 85% for 1K miles plus of highway.

[RiverRunner]

2024 Limited, HO 6.7 long bed. Yesterday I drove home from California to Oregon, 1K+ miles all highway 65 mph+. I looked down on my dash soon after I left and the DPF filter showed 83, 84 , 85%, going back to 83% during the trip. I was towing a small trailer with two road bikes, say 1500 lbs total. Still showing 83% full when I arrived home. I have never seen this gauge show above zero in 17K miles. This is not a daily driver. If it is running, it is usually hauling a 12-14K toy hauler. Anyone got an idea of what is going on? We had rode bikes from San Diego to Cabo and back to SD. Last Sat we drove through the northwest part of Baja where on Sunday the Cartels were burning and shooting up things, we just made it out in time. I feel really sorry for the people living there.

I can’t help with the DPF but glad to hear you made it out of that area safe. Pretty crazy stuff.

If it’s showing 83% on your EVIC, something is wrong with the system, as the truck should trigger a soot based active regen at roughly 40%.

Unless you are talking about using an aftermarket monitor (Banks, Edge, etc.), and monitoring the RG% PID. In that case, your soot loading could have been decreasing, but you are 83% through the 24 timed cycle to your next active regen.

Using the OEM gauge in the dash. I was worried the level would keep going up last night and we wouldn't make it home. So all is well. Appointment with dealer on Tuesday. It's funny, I still have a 2008 6.7 I bought new, now 145K miles and I've never had an emission issue....go figure.

My DPF gauge in the cluster has shown 0% since I got the truck. Seems weird to me.

As soon as my DPF gauge shows about 10 or 15% on the gauge from Dailey driving or just running around. I will hook my 4000 pound trailer up and go for about an hour cruise at about 70 miles Per hour and it drops back down to zero.

Its a good idea there for sure.

It’s just a shame that the DPF system on these trucks requires a needless expenditure of time and fuel to maintain them.

Yeah but remember-- needless extra driving and burning countless gallons of extra diesel fuel in a heavy-duty pickup truck is actually good for the environment. Don't believe me? Just ask Gavin Newsome and his unelected bureaucrat buddies at CARB.

Just tonite on my way home from work, a 34 mile drive, I was on the freeway exit ramp about 2 miles from home and BLING, I hit a time-based regen. Sooo.... back on the freeway, another 20 minutes and 15 miles of driving at 70mph until it finished. I'm literally being held hostage in a truck I bought voluntarily and paid $70k+ for.

No one is holding you hostage lol

If you don’t like it, sell the thing and purchase a 13-18 ram, as they have far less DPF related issues. You could also deal with the ford CP4 glitter, or the atrocious Gm 10 speed issues.

Pick your poison. You’re free to choose.

Can someone explain to me why they didn’t put a split connection on the front and back of the DPF so it could easily be removed for cleaning or replacement when regular regens aren’t doing the job?

They want to make big $$$ for dealerships.

But for me it'll have the opposite effect. First time my DPF goes on the blink it's getting tossed over a bridge.

This. Exactly.

If the regen sensitivity on my truck doesn’t improve, I’m not gonna fix it by spending thousands on more problematic parts.

Hi
Your dpf almost full means check you egr valve electrical first and than start from intake air coming or not air filter, Baro metric, Maf, CAC, Turbo, egr cross pipe, MAP, NOX 1 sensor, intake grid heater(possible soot) CCV filter, EGR bypass, and motor EGR Cooler possible blockage, one of them root cause.
Egr, Nox 1-2, EP pressure sensor EGT sensors PM sensor EGR bypass first check this electrical and mechanical if this one is working properly than start which I told you list. You can do it diesel shop force regen but it’s not solution.
Good luck
