Then I am confused, the part your picture shows is the part that the def gets sprayed into, I was under the impression the DPF was behind that, like in the picture below, I thought the dpf was part 17.. And when I look at the parts listing the part isn’t listed. The website I am on is Moparoemparts.com

Ok, this was very educational, not what I thought. That is why this forum is awesome.

Thanks for this photo as I had read that DEF was injected before the DPF and not after so the next time I see it posted wrong I can post this photo of how its done. so a big Thanks

The '24 and older trucks do infact have the SCR after the DPF, but on the 2025's they rearranged it and put the SCR in front of the DPF
That is correct.
On the redesign, the DOC is right at the turbo, then downpipe to the SCR (DEF injection is at the elbow joint), then back to the DPF.
Well, I finally pulled the trigger on the Ram. Traded it in for a Ford Superduty. I really loved the Ram for towing and a number of other things, but the uncertainty and frustration with the constant regenning of the dpf just got to be too much. Nothing about it made any sense and it doesn't appear that Stellantis cares about fixing it. My dpf % would even increase while it was actively regenning. In any case, so far the F250 performs exactly the way you would expect....no movement in dpf % when strictly highway....some increase when around town, but passive regen on the highway takes care of that. I also really like the idea of the OCR available on slightly older models, although I have not had it turned on in my F250 yet. I'll have to deal with the CP4 at some point, but I am less concerned about that for now. My last two trucks were Rams, but I think they have lost the plot on quality and customer excellence.

Joined the P2459 club this week. 2022 2500 with 37k miles.
Saw it was coming. Miles between last several regens was 73-65-60-58. Check engine light came on when the next regen started.
Going to pull an oil sample this weekend and send to get tested. Haven’t been checking oil level as driveway is too steep to get good reading.
Will contact dealer next week to see when I can get it in for service and see what they’ll do. Hoping a new DPF is in the playbook and doesn’t take too much to get to that point.

I recommend using the Fleetguard UOA kit #2543 or the UOA #2525 if your not worried about the TBN number, I also request them to do CG for fuel contamination on every test I send in, I have made up my own info 8x11 sheet of paper that I send in with every test so that they do not have a hard time reading my writing for the information about the engine or oil sample, in my note section I have the following words, (Please Do not Estimate Fuel Dilution for this engines oil sample. Please perform a GC test regardless of what any other values are.. This engine does not idle for long periods of time. Questions call or text me, THANK YOU…) You can get Fleetguard test kits at Genos garage: https://www.genosgarage.com/category/s?keyword=OIL+ANALYSIS+KIT

I took two samples using hand vac with sample tubing down dipstick tube. One going to Blackstone and the other to Horizon Oil Analyzers. Will ask dealer to also do a sample.
Oil on dipstick was at top of plastic section where it meets the metal but driveway is angled up so likely why high. Could be high fuel dilution as well.

Amsoil oil samples are sent to the same oil lab that Fleetguard/Cummins uses ( at one time it was a spin off company from Cummins/Fleetguard) the only difference is with Oil Analyzers if you want them to do GC on the oil they will charge you like 6-8 dollars extra where Fleetguard will not, I have learned that an oil test that shows 1< estimated can in fact be 1.9% when they use the GC to test the oil, it is why I always request GC even if I have to pay a few $$ more for it at Oil Analyzers...

My '22 is on its way to have the shortest regen interval since I've owned it, right now I'm at about 7 hours and 168 miles since the last regen which was soot based. My driving habits haven't changed much.
The truck runs great and has no other issues.
It's very frustrating.

Did the last regen complete or was it interrupted?
Generally a 24 mph average isn’t good for passive regen, but I’ve also seen it be fine. What kind of driving/idling are you doing in those 7 hours?

The last regen started and finished on the freeway, ive tracked every regen this truck has done, until the last regen the truck has been doing them based on time, the last regen was at 15ish hours and that was with about 4 hours towing a 20k fifth wheel.
I try not to idle much, maybe a minute after a cold start.
Most of the roads in my area are 45-50mph and I do some in town driving.
It's just really frustrating because I had an '18 HO before this one and I never had a soot based regen in the 38k miles I owned it. That truck had much more idle time and short trips and never an issue.

In 2022 the EPA issued stricter emissions standards. My 22 2500 started off with short regens. I think partly from breaking in and my gaining experience as to what was required, driving habits wise, and the introduction of Archoil products. Since then it has been pretty steady at 24 hrs between. But not long ago I got one at 12 hours that was completely unexplainable. I’m guessing it was the fuel bought during a trip that did ok pulling the trailer but not so good running around empty.
I got some different fuel and the Archoil treatment and the last regen was at 24 hrs and 1006 miles. I also did a parked regen after the last short one.

I’ve always noticed my DPF inlet and outlet pressure sensor delta to be above 1.3 or so when I go into a soot based regen, yours is not showing much difference and your at 6g of soot. Of course my screen shot is just after it went into a regen. Maybe something to look at.

Yeah, my 18 was a very different truck when it came to regens too.
The duty cycle doesn’t sound like it very passive regen friendly, at least that wouldn’t have been for my ‘22. Most my driving is on 50mph and lower roads, but I was able to maintain my avg mph in the low-mid 30’s. A week of driving to/from work was all the truck would need to switch from time based to soot bases regens, regardless of how much I had towed the weekend before.
I’d probably give a tank of archoil 6400d a try and then just monitor the regens. If they start getting shorter and shorter let them, wait for the CEL and take it in for the DPF TSB.
