Regens at alarming rate!

40% is normal, that is what my truck stops on for the finished regen with the OBDlink.

40 % is what mine drops to on the ScanGauge but while towing I have seen it get a little lower in the 39% range. When you turn it off for a little while it will drop back to the time setting.
ie every 5:46 minutes = .395% on the ScanGauge III. Sometimes it goes up.4% and sometimes.39%.

@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 had the same problem. Dealer said it was the DPF sensor which was on back order. I accidentally fixed it by replacing the trailer park light fuse! I have confirmed this fix twice on my truck.
 
I call bull on that. Though I did look given everything else hasn’t fixed my Frequent Regens.

Adding my truck to the list. 2021 2500.

Story:
Back in the spring at 48K miles, I had a “See Dealer” fault pop up. Instead of reading the fault I took the truck in to the dealer due to all the pending recalls that I was delinquent on. The dealer scanned the truck and said the MAF was bad and was a result of me not replacing the Air filter. Not covered under warranty…. They replaced both the filter and MAF for $600 along with all the recalls. Fault went away and everything seemed to go well for about a month. Then about a month later I had a DEF quality issue pop up. I cleared the fault and it went away after refilling. About 3 month later ~55K miles I have noticed my fuel mileage tanking 15.1 ,not towing, and about a month ago I got my first Frequent Regen code. I cleared it and started paying more attention to the regen. My regens were within less than 100 miles. I started searching the forums and replacing all the typical items. Air Filter and MAF again, checked the MAP and thought I had found it due to how it looked but I think I was wrong. Picture of the MAP attached. Replaced it with one from Genos.

My one question, is when I went out to train the sensors, just before I jumped on the highway another regen started. I did the train/relearn with the active regen going on. Is this correct or should I try to run through the drive cycle train/relearn process when its not in regen? That regen took ~60 miles to complete but after it was completed it restarted again after 70 miles.

This is a real PITA and I am getting very close to gutting the system or trading in the truck. I like everything else about the truck.

Which air filter is in your truck? And do you tow a lot and or drive a fair amount on the the highway/interstate?

Sorry to hear this, are you buying diesel that contains more than 5% Bio content, short city driving under 10 miles one-way and or a lot of slow city stop and go driving? I've learned in my truck that with Bio diesel over 5% its no friend when it comes to regens unless its driving on the hwy full time. You may or may not have some luck with a quality fuel additive like Archoil 6500 & 6400D or Hot Shot Secret every day use.

I did but some Power Services Diesel Clean to try today. Otherwise I was going to see what I can fix with a hammer.

Yes, do the MAF relearn in-between regens.

IF your DPF is face plugged as mine was, nothing is going to fix it. Consider having the DPF bore scoped. It takes a very small, and expensive, borescope to get in there. It is what if is, if face plugged, get if fixed. Look around, sometimes people delete their trucks and have good used DPF,s available, but they are heavy and hard to ship. It cost me $2500 at the dealer to have one installed. Or delete, but I like the clean smell of my trucks exhaust.

It was doing to many short drives, along with the air filter debacle, that eventually led to a face plugged and ruined DPF.

My truck runs good now. I recently installed the Banks Monster Ram Intake and Grid Heater Delete. When I took off my EGR crosstube, I was surprised, and happy to find only a light coat of soot. The old grid heater was clean too. My soot level goes up and down with the new DPF, I watched it the other day go from 85% to 64% in ten miles! I'm over 650 miles on my interval.

Yup that kills em. If I run to Lowe’s, 2 miles from my house a few times during the weekend, soon as I get on the interstate my DPF gauge will jump up 25% from where it was at before.

Have been unable to legally drive hard enough to keep this rig hot enough. Considering titanium exhaust wrap to hold more heat in my DPF and more easily maintain adequate temp (600-800F) for passive regens (2022 RAM 6.7). Looking for do or do not advice of wrapping and any adverse effects of this alteration on active or forced regens with >1150F temps. Thank you.

And, yep, using the 530....AB no glue air filter, truck stop pump DEF or BlueDef only, have run some HotShots cetane, but haven't tried the ArchOil yet, no idling except when hooking up the trailer, using gear limiter to keep rpms around 1800-2000. Rural mountain driving in 4th gear is only putting about 450F into that rear pyro.

Which is indicative of a huge problem in the system for certain.

The system needs to be able to function better than that. No wonder there is such a demand for weight loss on these expensive vehicles.

As soon as my warranty is up, the Hamilton cams kit & a diet is surely in order.

Where we spend our summers, in Libby, Montana, a very small town, everything is very close. That I was doing to many short drives, is not in question to me. It got away from me. But I was already having shortened regen issues, the short driving was the final straw. In the year long effort of trying this and that, it was in the end, a new DPF that was the fix. Towing would not clear the DPF out. When I bought my truck new, I never worried about the regens. And it is not unusual for us to get caught with this issue, without knowing it was an issue, until it is too late. I do know this, it was buying some cheap air filter two years ago that started this. Before that, all was good and proper.

This year, I bought a cheap 2007 Grand Caravan beater for $2875. Put about $400 in it to fix the windows, charge the a/c, extra keys, a better cheap usb radio, and it's a perfect round town dog hauler that gets good mpg. And that was the answer for me. It runs great and has already paid for itself imo.

There are services that clean DPF,s available, or used, there are options.

I think that’s the answer to regen issues. I don’t short drive mine and I also have a gas burner to do the short trips.
We just finished a towing trip and mine did great as far as regen frequency, but when we were empty and getting hung up in traffic jams, it would jump up pretty quickly on the EVIC and it would take a good bit running empty to get it to come back down. The DPF should have gotten cleaned out if it was going to. The EGTs stayed in the 800* range most of the time but did see some 900+* temps climbing hills towing.
The trip consisted of 98 hours run time, 4870 miles and 4 time based Active regens. No soot load based regens.

Don't know where you live but here in the PDX area of Oregon I don't need high RPM to get passive regens, I have had many passive regens on 2 lane county roads at speeds between 45-55 mph, my 24 hour regens can take around 16.1 miles in 19.38 minutes at 55 MPH, but have also had them take long in very slow freeway traffic jams..... I use Archoil 6500 in every tank and the 6400D every 5K...

I would counter that I live in the same area and do not get passive regens until I'm going 70+. Headed back to La Grande last week and it cleaned itself out nicely. I think I had my first timed regen.

My truck doesn’t even try to passive regen until I’m cruising at 75-80mph.

I must have a unicorn for an emission system because I can normally get passive regens with non stop engine speeds between 1200-1450 RPMs driving west on Hwy 26 from hwy 217 to Hwy 6 at Banks, I have learned a heavy right foot can cause my DPF gauge to jump 12% so I try to not have one...
