Automatic Regen too often

[19Ram2500.Mega]

Fueling calibration and delivery may indeed be part of the problem. However, I would expect more users would be experiencing issues if the software was at fault. Although, many users may not be paying attention to the regeneration cycles. They may be having issues but are unaware of it. Thats the problem with this problem, it can hide itself very easily if the operator isn’t paying attention, and moreover will not always generate a DTC. My own truck has never generated a P2459 but I can tell you it has been regenerating more than it necessarily should simply because I monitor all of my trucks functions very closely (sometimes to a fault). The data is a good way to see what the truck is doing, rather than simply relying on DTC’s. Which is what most dealerships will do. No DTC? = “operating as designed”

Understood. I'm wondering how many people are actually having this problem and aren't following forums or looking into it. I know there are several trucks at my local dealership experiencing the same issue, Some worse than others.

My particular vehicle goes into regen around every 20 or so miles, irrelevant of how it is driven.

I have spoken to many other people that are so frustrated they are looking to either trade then in for another brand or put them on a diet.

You and I have identical issues. I was regening every 20-25 miles. They've done a manual cleaning of the dpf, several forced regens, a new MAF, now they're moving onto testing the egr, fuel pump, injectors, and are going to replace the CCV filter with an oil change. My truck will have been at the dealer 2 months now this Friday

Every 20 miles or so no matter how it’s driven? you have problems other than poor fuel quality; which I believe plays a part in this whole mess with the tight emissions on these trucks do to the fact that the archoil seems to alleviate some soot loading issues; archoil can help with your soot loading once your actual issues are hopefully ironed out by the dealership.

There’s a lot of people that don’t even know how to monitor DPF performance on the EVIC. I would imagine it’s a lot more people having trouble and not knowing until the CEL comes on. What’s even more concerning is the lack of competent technicians capable of diagnosing the problem and correcting the issues. I don’t believe Ram/Stelantis/Cummins or whoever came up with the tuning for this would create what they did and then lock the door behind them to prevent any corrections.

Well I hope that works. Mine has a new fuel pump and is on its third set of injectors as well. It's has the dpf replaced, the catalytic converter replaced, pretty much everything you mentioned. Short of a new turbo and block, everything's new or newish. It has been in the shop well over six months in t

In total.

And who’s to say if replacing all of these different parts fixes the issue, 6 months down the road it doesn’t happen again. There has to be some commonality to the problem yet when someone else comes up with it they start back at square 1 and start all over again. It’s like they don’t want to figure out what the actual problem is.

Reminds of the movie Groundhog Day.

I agree, it's as though they are running back to square one, just to avoid addressing what is likely a much larger issue.

With fuel dilution being what it is and the damage it could be causing (wouldnt be surprised if my motor is smoked at this point), coupled with the cost of parts failing, it would seemingly be in their best interest to get this resolved.

I would gladly hand them my keys to use as a test case, if they gave me a similar vehicle without issues. That said, I would also like verification that they wouldn't just sell off my vehicle, to an unsuspecting person, just to make it go away.

Exactly like that movie

Just thinking outloud here, but on the trucks that regen under 100 miles and have had multiple parts replaced with no real solution I wonder if there is a internal hardware issue with the ECM causing bad injector control which coululd cause excessive soot to be produced, or something wrong on how it reads the differential pressure sensor or other sensor data. Does anyone know if ram has replaced any ECM's after every other option has been tried? It seems like it could be possible, especially with the chip substitutions during the covid shortages.

Evidently they don’t have anyone smart enough to look into that.

I'll ask when I go in late next week. That said, everytime I ask a question I get the "our technicians will have to diagnose it with Stellantis, I don't want to lead them. Also, when was the last time you changed the oil and filters? You probably aren't driving it hard enough". Then they swap a few parts, test drive it and if it doesn't throw a code in the first hundred miles, they hand it back. Code usually pops up in a few days to a week after getting it back.

Your theory would make sense.

I'd say at least you're getting a code. I wasn't getting codes despite a train of documented regens - usually multiple per day. The ram dealer refused to look at it until I called Ram cares who then called the dealer to take a look. They started with doing all the recalls and a forced regen. I picked it up, and the DPF screen was at 40% before even driving off. Talked to the service rep and tech who said "Oh you just need to drive it about 5 miles and it'll clear". Nope, I made a few miles and it went into regen. Called the dealer and they said to "bring it in Friday" which was way back at the beginning of May. Other then stopping by last week and pulling an oil sample that I mailed to fleetguard Monday - I pretty much haven't seen my truck since other then when I'd drive by the dealer and see it sitting. The dealer shares responsibility here too as my tech apparently quit the first week of June and no one touched it until both Ram Cares and I saw the star case was closed. So we both called to see what was going on. My fingers must've been faster because I got the service rep first who then informed me (this is on June 26th) that it had not been reassigned to a new tech and were "very sorry". This led to me getting the service manager involved, and I've been told my truck is now the priority of their most experienced and trained tech. I have met the tech now, and he at least seemed motivated by the words he spoke and what he planned to do (egr, injectors, etc).

Ultimately BS walks and money talks so we will see if I am a priority or not. Both the dealer and Ram cares have been advised I already rescheduled my vacation to the Wyoming mountains from June to August pulling a camper so it had better be a priority.

I wondered this as well. Might be the ecm at the source of some of these. Especially the ones where all the major components have been replaced.

Well, 32 pages long and I just don’t remember, what year is your truck and what are the lemon laws like where you like where you live? I had a similar problem, down to the camper and all, except I was going to the smokies and broke down pulling my camper. That was with the 6.4l (it was a turd), lemon lawed it and ended up with the 6.7l.

2022 with August build date, purchased at the beginning of October 2022. Lemon laws in Oklahoma are limited to the first 12 months after purchase with few exceptions (really none other then the law being vague on what those are) and all responsibilities fall on the buyer to prove they got a lemon. For the most part I think I'm on my own short of hiring a lawyer should it come to that.

My DPF gauge, too, goes up quickly when I go over 60mph. Takes a while at 70-75 for it to come back down. It’s as if it runs it worse around 60-70 mph and creates more soot there than slower. Above that speed is less soot and maybe offset slightly by higher temps in exhaust. #shrug

Interesting, good to know!

 

[TomTom]

That’s pretty common, most folks that have commented on that says theirs behaves the same way, mine included.

Interesting, I hadn't realized this. I thought maybe something was going on with my AGS or something else air related that was causing it. Thanks!

Groundhog day awesome movie.
To me this is hectic and it can be many tings or a combination of things.
The short story for me is the DPF should not regen that regularly and the reason is the DPF is getting full to fast and this means the engine is not burning clean and it seems crazy that the dealers are just throwing parts at it and not diagnosing it.
Now I am talking personal experience here, finding good techs at dealership level is like hens teeth. They usually pay below average and the saying goes you pay peanuts you get monkeys.

Happy to report have the last regen everything is working normal. Passive regeneration is back even with some idle time. Difference is shell fuel vs Kroger.
