Well as long as things stay settled until temps warm up for me in April hopefully a flash is available. Either that or I will find a new ecm for it. I really want to leave the power train stock as I’m actually happy with the over all performance for my needs.

Automatic Regen too often

Just to be clear, "passive regen" doesn't show on the EVIC. An Active Regen shows on the EVIC.

This is my preference as well. I’m completely fine with how it is stock. And would prefer to keep it that way at least until my powertrain warranty is up.

Unfortunately The dealer is correct in their answer. A stored code is a snapshot that just says this incident occurred but is not currently an active issue. Not much different than an intermittent short in your lighting system. The best and easiest way to diag the problem is with an active code otherwise you’re just chasing ghosts.
If you have the DPF gauge pulled up you will see all regen actions. Passive regen says “Automatic exhaust system regeneration in progress”. If the system is in active regen the message will include, “continue driving”. When a forced regen is required the gauge will turn from gray to red, the vehicle will go into a level of derate depending on soot level, and the new message will tell you to see dealer.

mine went into a "Active regen" this morning at the 24 hour mark. when it started it was just under the quarter mark on the gauge. cleared after 14 miles.
this is the 3rd regen since owning this truck. 1st was a 24 hour regen, second happened around 19 hours and the 3rd was at a 24 hour regen.
I filled my def tank at 1900 miles, and its used 1/8 of the tank in 800 miles.
yes, im keeping track as this is a 24 model and also a HO

Well, you're wrong about that.
The only indication you're in passive regen is the gauge going down, or if you're monitoring soot levels, that also going down.
The display you're showing is an active regen and that is displayed only when doing an Active Regen.

I am now asking for advice. I posted way earlier in this thread that if mine ever started doing this I’d either get rid of it or lose some parts. I do not need a diesel, I bought it because I’ve always wanted one, but I was well aware of the possible issues.
I’ve now for the last 6 weeks been averaging two Regens a week with anywhere from 200-350 miles in between and 4 engine hours if not towing, or 6 if I’ve been towing. This is all highway mostly 70mph+ and a couple weekend trips pulling the camper in there as well. This is how I’ve always used the truck.
I’ve thrown no codes so I know there is nothing the dealer can do. My question is if I want to keep it in tact do I need to accept that this is functioning normal for how I use it? And if that’s the case do I just change the oil more often or am I looking at trouble here? I’m only at 31k miles so I’m not sure I’m comfortable losing parts right now when I have 70k miles of power train warranty left. If I did that and then my lifters go out or something and I have to pay for that out of pocket that would be a real kick in the nuts. I feel like I need to make a decision here and I’m struggling with what to do. I really like this truck but driving it every day staring at the dpf gauge has taken the joy out of it. Any advice is appreciated.

keep running it. document everything you can. it will eventually pop a code i would hope.

I would keep it and don't lose weight while under warranty, I really do believe a recall will eventually happen for the regen issue. There is a TSB out for certain build dates for the 22's on that, and if you fall within those dates you might see some new parts installed, see post #1315 and print the two pictures and show the dealer. I also believe it'll eventually cover all the trucks effected. Just document and drive it!

Yep I have the tsb saved on my phone. I will continue to document all my regens as well. I’m going to run some archoil systems cleaner through and try running their additive on every tank for a while to see what happens. I figure worth a shot. Thanks.
I talked with the wife and explained everything to her. If it comes to it she would prefer I put it on a diet over giving up on it. She likes the truck and specifically enjoys how nice it pulls the camper.
An aftermarket monitor (banks idash, Edge CTS3, etc etc) is really a good investment for these trucks if you want to monitor regeneration cycles, and emission function. There’s a lot going on “behind the scenes” that the basic evic DPF gauge does not show.
Suffice it to say any message on the evic with regard to regeneration (either the normal one or the “continue driving” is indicative of an active regeneration cycle in operation. Passive regeneration doesn’t have any sort of notice since this occurs without any intervention or input from the truck. Its merely a byproduct of high EGT’s and isn’t a scenario the truck can create on its own.

The 2022’s emissions woes seem to rear their ugly head around the 20-30k mileage mark. I suspect yours is likely on a downward trend. I would continue documenting for now and avoid any fuel additives that might prolong the inevitable. (I’m assuming yours is a 2022?)
Time is the factor that triggers the P2459 DTC and that time value has to get very short in order for the truck to generate that code. If it does, and your truck fits the build date requirements for the new TSB 25-005-24 for this issue, I would take it to your dealer with a copy of that TSB in-hand and have them carry out the required DPF replacement. That being said, there’s been a massive spike in DPF procurement in the Mopar parts network within the last week (I wonder why?). Thus you’ll likely be waiting quite a while for a replacement.
Regardless. Documenting is key. Document everything and compile your data. You’re within the emissions warranty period. And if your truck is a 2022 that got Y43 completed, you also have an additional one year unlimited mileage warranty on your DPF.

I'm curious if the oil change intervals as suggested by the EVIC could be causing these regen issues (at least partially). Starting about 10 days ago I was regularly getting quick soot build in the mornings. It would go from 0 to 13% to 25% to about 33% in 10 miles then would take the rest of the day of highway driving 70+ to work back down. 8m a contractor and my current jobs are 70 miles away so I'm driving about 160 miles round-trip daily as I have several jobs going north of OKC. Changed my oil 3 days ago at about 6300 miles on that oil. Since the change I have not had any more soot build like I was having. So I'm wondering if "dirty oil" could increase the soot being produced. Just for reference I use 10w30 Valvoline Premium Blue.
Just a reminder my DPF and MAF were changed out about 6400 miles ago after my daily regen issue. Build date 8/2022.

It seems like anything outside of the ordinary on these trucks causes problems until it can eventually readjust. I try to change my oil right after a regen so that there’s 1 less regen event on the oil. When my truck was newer it seemed like changing the oil would make it regen early very soon after changing it. That was running Rotella T6 5-40. I switched to VPBE 5-40 and keeping up closer with the regen cycle and it doesn’t seem to effect it on mine. I’ve tried opening the door twice and standing on one foot or the other with one hand on my head and just haven’t quite figured out the right combination yet. Now looking for a monkey foot to wave over it and see if that helps. IDK
I hope that didn’t come off as being sarcastic. I’m retired so I have plenty of time to wonder what could possibly be a solution. I’m still just as confused after owning the truck for the last 18 months as I was on day one. I can get 24 hr regens back to back for several times in a row and then suddenly get 10 hr regens back to back with the exact same drive cycle. Still can’t correlate weather or temperature and no way to check fuel quality other than getting it at different locations.

Haven't updated this thread on what I'm seeing in awhile... Basically all of the following is w/o towing.
Mine had a bad lifter bore and thus a lifter tick which drove ultimately to a replaced short block. Before the new SB it was averaging ~350mi - 450mi (10-14 hrs) per active regen. After new SB, for the first ~1500mi it seemed to be about the same, but I was babying it. Changed the oil they put in(rotella t6 5/40) at ~500mi and put in rotella t6 10/30... No change. Started the archoil regiment and saw improvement initially like others with the 6400 which then tapered off in subsequent tanks of double dose 6500.
Stopped babying it once I got the oil analysis back. Now, with a new job which is just under 1hr drive each way with most being interstate.... Happy to report it's 4 or 5 24hr regens in a row.
The evic does come off 0 @ ~300mi after last active and floats up and down between 0 and 1st tick mark.

Sorry for the late response, I was out of town all weekend putting up deer stands and had no cell service. Which is a wonderful thing sometimes.
Yes mine is a 22, built on September 23rd so it does fall in the TSB window. My truck also did have the Y43 recall done. It was done a couple days before I bought the truck on 8-8-23 . It was a brand new leftover with 18 miles on it. So thanks for the info on the warranty for the DPF, I did not know that. I will refrain from using the additives for now as I don’t see it being long until it throws a code.
I started tracking my regens on 10-7-24, since then I’ve had 6 regens in exactly two weeks time. In that time I’ve driven only 1,329 miles and 23 engine hours of drive time. Almost half of those miles have been towing and it’s all highway. I changed my oil only 5,400 miles ago but with all of these regens I think I should change it soon. It actually did a regen twice last Friday. Once on the way to work and then again on my way home. I always let them finish before stopping or shutting the truck off. I attached a picture of my regen’s since I started tracking. I have pictures of each time as well.
Thank you for the reply and info.

Yeah that looks pretty close together. I’d say you might be a candidate for the TSB if the code trips
