Regens at alarming rate!

[steve49]

Which one of these Scangauge II EGT settings is the one to watch to see if the temp is getting hot enough during a full active regen? Thanks!

Exhaust Gas Temperature 1 – DOC Inlet (℉)

Exhaust Gas Temperature 2 – DOC Outlet (℉)

Exhaust Gas Temperature 3 – DPF Outlet (℉)

Exhaust Gas Temperature 4 – SCR CAT Midbed (℉)

Exhaust Gas Temperature 5 – SCR CAT Oulet (℉)

DOC outlet and DPF outlet - above about 600 f or so and you should be in passive regen. Don't worry your self about trying to get temperatures in range though just drive it. In active regen i have seen both those numbers get to above 1075F and approach 1100F.

Well I've just joined the P2459 club (too many regens) after a full filter the other week. I'll update if I learn anything interesting.

If any of you happen to be in one of the four Pacific Northwest States and are experiencing frequent regenerations (with or without DTC’s), please speak with your dealerships service manager. Ask them if they received any emails from their Stellantis Regional Tehnical support team regarding the regen frequency issue.
Word on the street is Ram is aware this is an issue and is actively investigating.

@RamCares I hope all is well with the team.

I own a 2022 3500 6.7 CC SB picked it up last Dec 4. Amazing ride, comfortable, quiet, and decent fuel milage, believe it or not 24 mpg for a trip from Va to Fl and back to Va.....other shoe drops. Three weeks ago, my DPF climbed rapidly 0% to approximate 32% in a day. The next day July 2nd it went to approximately 45% and then the regen started, within minutes the DPF showed 100%, CEL, reduced power, see dealer. So within one hour I am at the dealer. Can't help you need appointment. Scheduled appointment for July 8 @ 0900. At appointment, mileage 12,255 when checked for appointment, diesel tech takes truck, does a computer reset/forced regen to see if it would clear the CEL (3 codes were showing, don't recall what they were). An approximate 45 minute forced regen was done, no codes, no CEL...cool. Tech takes truck for a drive (about 25 miles round trip), when he gets back truck is doing an auto regen...second regen now in three hours. I drive home truck finishes regen during drive. July 12, auto regen. July 16 auto regen, July 21 (TODAY mileage 12, 693) auto regen. My DPF goes from reading 0% to 45% approximately in less than 50 miles before every regen. Dealer says there are no TSB's, recalls, notices, holy F's, or anything. Five regens, including the manual at the dealer in less than 500 miles. I believe it is a bad sensor. Dealer noted that there was a similar issue with the ECO Diesel, and it was resolved. BTW, mine was the first 22 at this particular dealer for this issue, they had seen it in older units.

Any info besides...there is nothing, will be accepted.

Thanks for your time.

I have the same exact issue on a 2023 with 6,300 miles. It's a 3500 CC LB dually

I updated my thread on my issue but I’ll also post here. After replacing the air filter with the proper part number the truck didn’t Regen once nor did it even get above 0% on the EVIC! Huge difference from last week where it Regen’ d all the time and threw that error code (too many regens). Loving this! Towing tomorrow so will log and see if it’s happy as well.

So either wrong filter or dirty filter… or a combo. It did likely get installed at 48000 km and now I’m close to 80,000km so could simply have been dirty. Though now I am swearing by the proper filter just to be safe and it will get changed likely every oil change or so.

Thanks for this thread as so far it might have been my smoking gun!

I'm assuming you mean air filter?

The wrong air filter can absolutely cause aa regeneration frequency issue.
It’s been noted in enough STAR cases that supposedly Ram is actively investigating this at the engineering level.

 

[Riddick]

I installed a wix air filter about 3 months ago and have definitely noticed more regens since the install. I have been watching this and other threads anf I decided to go swap my filter to an oem one.

One thing I noticed on my wix filter is that it was made in Mexico, in a different thread somebody posted a picture of one from China. Mine also has the pleates glued together. Here are a couple of pics for reference this filter was purchased 3 months ago from RockAuto. This filter has about 1500 miles on it.

Yep the Wix / NAPA 6930 design has been changed at least two times in the past two years. Its country of origin has also changed. The original ones were made in the USA, had orange foam around the top, metal mesh on the top, contained no glue strips, and was a spot-on match to OEM mopar 53034051AB.

 

[Firebird]

I'm hitting regen now every 3 to 5 days, will switch back to an OEM air filter to see what happens

 

[mbarber84]

I guess the time has come….

Start getting your info together. I’ll post an official thread when the spreadsheet is ready to go.

AIR FILTER?

A few thousand miles ago I replaced the factory air filter with a new on from Autozone (Wix) and didn't think anything of it.

I noticed two things, but it took until this thread for me to suspect the air filter. First, many more Regens, averaging about just over 100 miles each, with the Regens taking about 26 miles each. I thought it was because I was taking short trips over teh last few months. Mostly only city, with a little bit of highway. The other thing I was noticing was after the first start of the day, I'd get some initial acceleration hesitation leaving the neighborhood. By the time I got out of the neighborhood, it would be gone and not come back. Both symptoms have been going on for a while. I was also suspecting lower mpg's.

After reading on this thread, I went to the dealer and a new air filter and replaced it. While it has only been two days, the hesitation after inital startup completed went away. I'm at 85 miles and only have 1 tick mark up on the DPF which is an improvement so far. I also feel like I'm maybe getting better mpg's. So I'm hopeful!

I have attached pictures of what I took out (yellow) and the new one I put in (white) from the dealer.

You brought up an interesting point which is the hesitation at initial start up. I changed my fuel filter and air filter a few months back and I have been experiencing the same thing. Mine only did this on cold starts and it was during my initial acceleration, it felt like the truck would shudder for 1-2 seconds and clear up. Initially, I was thinking something with the transmission and have been monitoring to see if it got worse. I changed my air filter back to OEM this past weekend and while I have only driven a few times so far my hesitation/shudder appears to be gone.

I will ask the million dollar question, what is different between the filters to cause this issue/excessive regens, is it an airflow issue?

That’s a great question. I’ve yet to see a definitive explanation or answer. There is something different.

I am only speculating.....but I think the issue is that between the turbos, engine, and emissions, you have a triangulation of tolerance of air. Three separate things but related to air that all require specific tuning. The engineers programmed everything based on the OEM filter (which makes sense). The after market air filter looks similar but they are different for sure in material and spacing. By changing air filter (and flow) a fourth variable was introduced that previously was not a variable, we possibly introduced chaos into the system. Ultimately, I think the engine is doing its best to stay within parameters, but in doing so, the other side of the balancing equation is extra particulate (i.e. poor fuel burn, either too much or not enough). Because I do not tow, I'm not running hot enough or long enough to burn it off to over come it, thus my DPF fills up.

Or I am just totally talking about out of my...., but it's more of an explanation than I'm getting from any dealer. So yes, that's a long winded answer I think it might be an airflow problem. lol

 

[mbarber84]

The composition of the filter, the material used to make the media, the number of pleats and their spacing, and the general CFM rating of the air filter would all play a part for-sure. Add to that variations in manufacturing. The WIX / NAPA 6930 is a perfect example. Over the past two years, that filter has changed design and build specifications and manufacturing locations at least three times. The most recent iterations having glue strips and known to cause P0299 and P2459 codes.

 

[kanigie]

I installed Fleetguard filer p/n AF27684 to replace a unknown filter with glue strips. I did notice the fleet guard filter had glue between the pleats but not a glue strip. 500 miles later, regens are still happening every 100 or so miles with 60 miles needed to regen DPF. Last regen was came with a P2459 code and took 150 miles and 2.5 hours or highway driving to clear DPF.

I just order the mopar p/n 53034051AB to try.
