Automatic Regen too often

22PearlRamMegaHD said:
So an update on mine - hope mbarber, olejoe, etc see this.

Picked mine up today after over 70 days at the dealer. 480 miles put on it since dropped off. 28,080 miles on pick up

The bad - despite nearly 10% fuel dilution they were adamant that it was due to the extremely excessive regens. All they did was a basic pressure test using the computer. No dye, ohm, or sending injectors off for proper testing.

The interesting - he showed me my old dpf and a new one. The old dpf was at least 4" but probably 6" shorter front to back compared to the new one. The new is also completely bolted in with flanges for easy removal and cleaning. Old one was welded - he hadn't had the old one from my truck sent in for testing yet but the exhaust was largely one solid piece. Ram was requesting mine be returned to them for some reason. He said for the 22s that for some reason, likely parts shortages, ram knowingly used inferior parts. In this case DPFs that are not capable of dealing with the soot of the 6.7. This problem is further exacerbated by the German MAFs. He advised the the MAFs screwing up, paired with an undersized DPF - that once the MAF starts sending the wrong readings the undersized DPF cannot catch up even with "normal" regens. They are set up to fail essentially (my words) but greed to push trucks out the door meant they rolled the dice figuring they'd make more profit then any losses by the time most people's emissions warranty ran out. In Oklahoma emissions are 3 years 36k miles. Mine failed in under 28k miles.

Lastly, he point blank said that the new MAF and DPF and most recent flash should solve my issues... we shall see as I plan to do an oil change between 2-3k miles since my 9.3% fuel dilution was at 2700 miles on the oil. Then I will do another OA on that change.

With all that said I'm not happy about the lack of fuel leak testing, but I drove it 375 miles to my old hometown in Kansas for the weekend and will drive home Monday. 375 miles, and the DPF gauge didn't move off 0. Average speed was 72 mph with less then 10 minutes (I clocked) idle time for the drive. I got 19.8mpg hand calculated. Fill before I left and again upon arrival. My hopes are essentially nothing, but maybe some headway has been made. I told them my plans for the next oil change and OA, and that if dilution is high a very unhappy person will be returning with fleetguard OA in hand AGAIN...regardless of if I have a CEL or not

I would very much like to see pictures of all of this. I’ve never heard of a DPF being bolted in. All of the ones I’ve ever seen were a one piece unit with the DOC attached and all welded construction. If what he’s telling you is indeed true, then it would explain why 70% of the trucks I’ve documented are all 2022’s.

As far as the undersized dpf goes I’m skeptical about what he is saying. The dpf length has been the same from 19-current and there are a whole lot of trucks out there without regeneration issues.

I would very much like to see a picture of the new one myself. Mine looks like the one in the picture.
The solution I’ve found is a 4” muffler 54” long. Lol

How many of the ones without issues are:

1. Towing constantly?

2. Operated by someone who pays no attention to the regeneration cycles?

3. Operated by someone who doesn’t even know what regeneration is?

Oh heck we all know that customer base, but then there are us forum members who are more in tune with their trucks. These are the customer base that I am in touch with. I frequent more than this forum and like I said there of plenty of people out there without regeneration issues.
As far as #1 in your post there are people who tow constantly and still have regen issues…

I agree with what you are saying. I asked 1 guy if he has had any regen issues and he told me he thought it had an alternator.

I’m inclined to believe there are far more trucks out there with regeneration issues than what we’re able to “see”. I just think a lot of them go unnoticed because the operator is unaware. In fact, I think there might be a connection between frequent regeneration issues and premature valvetrain wear on some of these. I never had a problem with fuel dilution in my 2017, but it seems like this 2022 is more prone to it. I’ve been fortunate that my numbers have been within acceptable range, but I’m seeing some wildly high numbers reported by trucks that are otherwise “operating normally”. As for the trucks having regeneration issues when towing, well those are 100% component failure in some aspect as that absolutely should not be a problem.

It's raining but I'll work on a photo. It didn't look too different from the picture on the prior page, but when he showed one then the other the sizes were more evident.
 
My trouble free (so far) 2024 looks the same as the picture. Approximately 39 inches long. There used to be a sticker but it's burned off/melted. Stamped numbers/letters have a date of 08/31/23 time 23:37 and the only thing that appears to be a model number is A-439 L-6405861BG R-RCP500099. Google doesn't find anything for that though. That info is right above the crossmember, kind of a pain to see.
 
This is what they installed. About 10-11" between "can" welds. The bolt flanges are approximately where the cross member is on the left side of the photo.

Sorry for the poor photos. It's rai ing pretty good, and I don't have anything to lay on to get more/better overviews

Where did you see the stamped info? Once it dries up a bit here I'll see if I can find that stuff on mine

Bottom of the DPF just above the crossmember to the right in your photo. You can see part of it in my picture here. Unless I'm not seeing it in your picture, it looks like there is some kind of notch in mine that your's doesn't have. Or I suppose your notch could be somewhere else higher up. View attachment 75226

Here's what is on my exhaust

Pics of mine from my '22
I couldn't find any part numbers on it that turned up results on a google search

This the length of the filter area, I put the other end of the tape in the center of the weld
