Regens at alarming rate!

Same issue on my '21 SO 2500 CC. I have been having a p2459 code every 600 miles. I brought it in to be seen not long after having my first p2459 code repaired because my oil test report said I have 10 percent fuel in the oil. Dealer said to keep driving it and to bring it back for them to service and do their own oil sample. I noticed my milage went down on the lie o meter and that it seemed to regen excessively. I then had my second excessive regen code. I have had 3 p2459 codes in the last 15-1800 miles and am unable to smog it because of codes and ECU flash. The dealer kept flashing the ECU with the tune for a truck that does not regen enough according to service writer. They gave it back and said no concern but wrote on the ticket that it had a NAPA air filter in it and the tech bulletin said that was the cause. Here I am 600 miles later taking it back to the shop.
It would regen 3 times a day in freeway miles. I can watch the DPF gauge climb while accelerating on the freeway. The truck ran for 9000 miles with that filter with no issue.
They will not consider any of my suggestions, like turbo line oil leak, injector, boost leak. They said they can only do what FCA advises. Then said they need to keep it again and drive it again and may have to "throw parts at it". If I didn't care about the warranty or live in CA, I'd repair it myself and delete it. Glad it was the WIX filter.
It's in the shop now and they are throwing parts at it. I took it for a drive Sunday night to video the regen cycle before my Monday appointment. Basically it regen'd 3 times in 50 miles at highway speeds. I gave it to the lead diesel tech and he started with replacing the EGR and a STAR case. Truck has 21500 miles.

I just had my ‘22 at the dealer yet again for similar issues. It’s ridiculous how many issues this truck has had already with only 13k miles on it. One of the most recent issues is that about 500 miles into a road trip while towing my toy hauler, I got a message stating “Service DEF system. See dealer.” I was in the middle of nowhere in New Mexico so I checked what I could and it didn’t seem like the truck was having any issues. So I ignored it and it went away and never came back over the next 3500 miles. After the road trip I had to take my truck in for other issues though, so I had them check on that service DEF message as well and all they did was a forced regen, which is what they seem to do every time I’ve brought it in and it obviously doesn’t fix the underlying issue. When I left the dealership my DPF filter was at zero. After the 12 mile drive back to my house my DPF filter was showing almost 1/4 full already. Then after another 25 mile round trip drive the DPF filter was showing almost half full. Now I’m just waiting on the dealership to call me back so I can have them start a STAR case. Sounds like a lot of you guys have already done that though with not much luck. It would be nice if Ram would figure out why these trucks are having all these issues.

Hi Tyler,
We're sorry to hear about that. Do you happen to have a case number? Please send us a private message with some additional details, including your most recent appointment date. Thank you.

I had the same issue nd discovered is was being caused by an Air Filter change to a K&N filter. First mechanic said no way it could cause this but next mechanic Sid to change the filter back to a Mopar nd see what happens. Problem solved.

I have a 2022 2500 Cummins with the same issue, I have 5,100 miles on the truck. Took it to the dealer yesterday they did a stationary regen I then took it for a 60 mile run. The truck went into regen mode on the highway for a little while then the error message shows DPF full power reduced (didn't notice a reduction in power) see dealer again. I watched as the DPF guage went from 0 to 100% in 30 miles. Not sure what to do, does anyone know if they can be turned back in under the "Lemon Law"? And to top it all off the local dealership will be closing it's doors next week..

2020 2500 CTD. About 37k miles on it.
Was getting regens <100 miles, even with brutal mountain driving. From time to time I was getting P0299 codes during city driving. Truck finally threw "DEF Full See Dealer" message.
Dealer pulled codes P1451, P2463, P242F. DEF soot was at 10g. Performed air leak test and found that both charge air cooler hoses were leaking. Repaired air leaks, verified no other leaks, performed stationary regen. Drove and code P1451 came back. Found that DEF was face plugged.
DEF replaced with new gaskets and clamps (warranty)
Charge air cooler hoses (68357482AB, 68417829AC) replaced. Dealership claimed not warranty items. I pointed our page 14 of the Warranty manual (Federal Emissions warranty section) where Charge Air Cooler and associated plumbing is listed as the second bullet point item. Service manager is researching the issue. "We don't go to the statute, we plug the item into Chrysler's system and it tells us if it is warrantied or not."
As a bonus they did the Y78 recall (HPFP) while I was there.

Interesting. I appreciate the info! Mine was still a stock air filter though but when I got the oil changed at 13k miles they said it definitely needed replaced so I just had them do it. Then the DPF filter filled up to 1/4 full after the 12 mile drive home.
Check and see what air filter the dealer installed. If they put 68517554AA in the stock air box, that might be your issue. Need to use Mopar 53034051AB or Fleetguard AF27684

Boy am I glad I saw this. Active regen 3 times on this tank of fuel. 70 miles of highway driving today and it went from 0% (I drove it yesterday on highway until regen finished) and it's 25% full. Had the oil changed in North Carolina dealer while visiting in Feb and just checked the receipt - PN 68517554AA. So is this not a Mopar filter - new style that replaces the 53034051AB? Going back to selling dealer next week and he has both in stock - might just ask him to change to the older PN.
68517554AA is indeed a mopar filter. However, it is not the correct Mopar filter for a 2019 and up truck with the Cummins.
You want 53034051AB. Or it’s Fleetguard equivalent AF27684. Both are identical and what should be in the truck. I can’t say with 100% certainty that this will correct your issue, but it has proven to do so multiple times. Is your truck a 2022?

2020 HO. Curious why it isn't the correct one - fitment or just an 'improved' version? I called the dealer that serviced it and for my VIN, the 685175544AA shows up as a replacement for 53034051AB.. Called the selling dealer in CT and they have both.

I’ll check the actual filter in my truck to be sure but according to the paperwork they put in the 53034051AB so that shouldn’t be the issue with mine.
Worth checking with your own eyes.
Both will physically fit in the air box, but the 68517554AA has been known to cause issues. It is slightly different in its construction and also has the glue strips on the base of the filtration media. It also seems to use a different type of media. I wish I could say exactly why this is the case, but I can’t. There’s just not enough data out there to go on. There is a note in the mopar parts system under “tech tip” but they have to actively click on the little icon to see it. The note tells them which filter to use for which application and the 53034051AB is for 2019+ diesels. 68517554AA is for 2019+ gas trucks

So, just worked through this with the North Carolina dealer. This is a Mopar fauxpas. If parts enters the VIN when getting parts, it will automatically supersede to the 68517554AA. There is a tech tip associated with this that says 68517554AA is not the correct filter for pre-2022 Cummins. 53034051AB is the correct PN, dealer parts confirmed and is sending me a replacement and the tech tip number. If I had to guess (and I very well may be wrong), the newer filter to accommodate the DPF sensors that Stellantis didn't have for 2022s?
Correct. I posted that information here previously. I have a whole thread on the air filter problem here:
6.7 Engine Air Filter Confusion
Wondering if someone can shed some light on this issue. I’m being given conflicting information regarding the engine air filters for these trucks. My dealer parts counter, as well as the service techs are telling me that engine air filter # 68517554AA is the correct engine filter for my 2022...
hdrams.com
I don’t believe the filter mix up / substitution issue has anything to do with the missing particulate matter sensor. I think they’re just coincidence. All that sensor does is monitor the exhaust stream to make sure almost no soot is exiting the DPF. It basically just counts soot particles in the exhaust stream and measures / compares the reading with a preprogrammed threshold.
There sure is a lot of confusing stuff with these big trucks. I've been driving Toyota trucks from 1985 to 2022. Just never needed a big truck. The only problem in all those years was a loose decal on a tailgate. That said, I really like our 2022 3500 HO. I like the features, the looks, the power, the tech, and really like driving it. I'm a bit dismayed by all the seemingly random problems reported on the forum but I know the other big truck brands have their issues also.
I am curious if any knows why a different air filter should impact DPF clogging or regen frequency.
The Mopar estores list both of these air filter part numbers as fitting the 2022 3500 6.7L Cummins. I haven't yet checked what is in our truck but want to. The 2022 has 9K miles. That brings up my other question. I tried to look at the air filter the other day. I loosened all the screws but couldn't get the top of the filter housing up enough to see the filter. The front left corner of the housing top is underneath a frame brace/bracket. Do you need to remove the piping between the filter housing and the turbo intake so you can slide the top of the housing toward the engine? What is the trick or secret so I don't foul something up?
Thanks for the help.

Dodgeman, yes it's best to loosen the big hose clamp and slide the rubber elbow back, then work the box cover out.
