Regens at alarming rate!

[NVYCHF]

@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.

Looks like you may be in for a new DPF soon or the DPF particulate sensor is faulty

I told them it is probably the sensor, until a TSB or recall comes out that won't cover it even under warranty. Sensor clear and CEL goes out...nothing to see here folks!

Thats a load of crap the dealer is taking you for a ride, its Absolutely a warranty issue

I suggest you contact Ram cares and voice your concerns over the dealers lack thereof .

My 2022 3500 6.7 CCSB build date 11-3-21 and I also picked up my truck in early December at Mark Dodge now with 10,241 miles is doing the exact same thing, right before moving back to Washington from Wisconsin right after the 4th of July my truck started a Regen. While driving to Wausau it goes into regen, 3 miles later I get the Exhaust Filter Full Power Reduced See Dealer even thou the DPF filter screen says it was at 45% before the CEL, I turn around and finish the regen and stop by the dealer to clear the CEL before my trip out west. Since getting out west my truck is doing a regen every 4 hours and an average of 80-156 miles before it goes into regen again. I have been doing 70% hwy and 30% city driving. I have an appointment on Tuesday to have it checked out as I cannot afford this thing burning diesel at that rate.

BighornHDRam,

Good afternoon. I picked up my HD from Mark Dodge Dec 4th, you? When I picked it up I specifically asked about Recalls and TSBs, and was told by Aaron that active Recalls and TSBs were taken care of. Did you use a reader to gather your data? I have milage, def, et cetera at every fill up. But I would be interested to see the deep data. Your "3 minutes at 45% before the CEL" is spot on.

@jebruns thanks, that is the same letter I got back in July of last year when I ordered my truck.

@RamCares anything of value to be added?

Be safe,
Randy

I picked my truck up December 9th 2021 at Mark Dodge, best truck deal I have ever dealt with with those friendly guys there. Mine was not 3 minutes but 3 miles after regen started that it popped the CEL and Exhaust Filter Full Power Reduced See Dealer. I did not get the code from the dealer as I was in a hurry to get things done for my trip. After I started seeing all the regens I created a spread sheet in excel to document them for reference.

As you can see in the pic my truck only had 6627 miles before the CEL popped up and Exhaust Filter Full Power Reduced See Dealer, it has been doing a regen every 4 days through the month of July. I thought the 2k mile drive out west would of cleared any issues with the system.

 

[rsday75]

Not a 22, but my 19 goes back to the dealer next week for frequent regens.
This time, they are replacing the DPF. They have replaced sensors, done forced regens, nothing has fixed it.
They have a case open with STAR as this isn't the only truck the dealer has with this particular issue.......
I am getting a regen every 50-100 miles unless I have my 15K trailer attached, but not exactly convenient to drive with a 40' trailer loaded down all the time.....

Interesting since my Y78 pump replacement and reprogram I am getting frequent regens as are others. My service manager is consulting with STAR

 

[BighornHDRam]

Yesterday my truck was at the Ram dealer for this ongoing regen issue, they checked and no codes present even thou in early July back in Wisconsin my truck popped the CEL and Exhaust Filter Full Power Reduced See Dealer and I had them clear it for my trip but I did not get the code from them. They tell me there is nothing to do until a CEL comes on and then they can open a STAR case for frequent regens.

When I drove the truck to the dealer on Tuesday it had just done a regen the night before, I drive to the dealer 17 miles away all 45-60mph and when I get there the DPF screen still reads 0%. I leave the dealer and within 2 miles it's at 15% on the drive to Fisherman's Marine that's 7 miles away on I-5 65mph. I leave Fisherman's and get back on I-5 going 75mph going to Woodland 27 miles away, the DPF goes from 15%-35%. The drive back to Vancouver WA on I-5 going 75mph and it's at 48%. Start the truck today on the way to the gym Boom another regen in 2 days.

So since Ram is not going to do anything I ordered a new Differential Pressure Sensor 68312096AB and the 2 Differential Pressure Hoses 68376348AB upstream and 68376349AC downstream to see if this will fix my issue.

@RamCares any help you can give me on this as the regens and fuel prices are killing me at this rate and the dealer was worthless without a code.

Any updates on when the DPF sensors will get installed. I'm almost 5,000 miles and I've gone through two fill tanks of Def... it's stupid the amount I'm tuning and burning

My wife thinks I only have 3 guns

Are you getting excess regens?

DPF regens don't really have anything to do with DEF usage/dosing. Additionally, 10 gallons of DEF in 5K is 500MPG which is about what everyone gets not towing. I only get 350MPG DEF pulling 16K.

Today I got the new Differential Pressure Sensor 68312096AB and the 2 Differential Pressure Hoses 68376348AB upstream and 68376349AC downstream and installed them. Took about 30 minutes all in all. I also changed the air filter today at 12180 miles while I was at it to see if these changes will effect my regen issue. When I had the dealer look at my truck for this issue on July 25, 2022 they applied TSB 18-094-22 that has had no effect on the regen issue.

Here is my current regen rate as of late.

I have been watching this thread with some interest. Maybe I'm worrying about nothing, just seems like the '22s have some ... issues in this area my 2020 did not seem to have. (I have a 2022 HO). Close to 10k miles, I've done several empty trips and pull a ~15k 5th wheel. (I really need to run it over the scales). Anyway, I don't have another vehicle and don't really want one, so it's a daily to run around town and do errands when I need to, before someone tells me I shouldn't use it for a grocery getter. I don't like to do the short trips, but that's my situation. Having another vehicle around really isn't feasible, though I'd love to find something sporty, the appropriations committee (i.e. my wife, will not approve the expenditure, lol) I haven't gotten any codes, but I did recently get a pair of Banks iDash monitors and I love the visibility. I need to start some data logging, but I haven't gotten around to it yet.

I monitor the miles between regen PID, there's a DPF % PID (can't remember exactly the name), when it goes to 100% regen kicks in. It's no surprise when I have several short trips around town without pulling the camper, my miles between regen drops to around 320. Pulling/empty and highway speeds I never see much in the way of regens except the ones that are time-based.

An observation/theory I'm forming is the conventional wisdom around locking out 5th/6th gears when going around town is actually not as helpful one might think. Volume of air going through the system isn't has helpful as higher temps. Watching EGT1/3, the temps are a lot higher if I let it drop into 5/6th gear and lug a bit. I did some research and it's basically air volume -- more air at higher RPMs actually cools things down and higher temps should, in theory, help passively regen/clean. Far as I can tell, my DPF is currently 'clear', the % 'full' PID was at 17% when I got back from a trip this morning. I pulled the trailer this weekend and it did an active regen right when I hitched up. I'll see if I can add some more data on a truck that's ostensibly working (mine )the way it's supposed to, although 3xx miles between regens kinda sucks IMO. Not as bad as what you're seeing, but not great.
