Regens at alarming rate!

The rear mounted water separator will usually be pretty dark in color after a 10-15k interval. In most situations the black color comes, not from dirt, but from small particles called “asphaltenes”. They’re a tar-like byproduct of high pressure common rail fuel injection. The 25-30k psi fuel rail pressures tend to heat the fuel to extremely high momentary temperatures. When that happens, the asphaltenes are generated as a byproduct. They are harmless to the fuel system as they are soft a pliable but the filtration media in the two fuel system filters will capture them. The water separator, being the first in line, captures the vast majority of them. This is yet another reason why the filter intervals shouldn’t exceed 15k. It’s also a good reason why you should avoid running the fuel tank lower than 1/8-1/4 level. The quantity of fuel in the tank helps to dissipate heat in the fuel. The lower the tank level, the hotter the fuel will run as it has less volume to draw heat away. The hotter the fuel is entering the system, the more asphaltenes are generated and so on.

That's probably why mine looked so clean after the first change. I rarely let my 50 gal tank fuel level drop below 1/2 or at most on a long trip, 1/4.

Definitely helps. I’m a big proponent of “1/4 is empty” for a whole bunch of reasons.

The missing Particulate Matter sensor would not be the cause for frequent regenerations, as the sensor’s sole purpose is to detect the amount of soot passing out of the system. If the amount of soot particles gets too high, it will trigger an error code to indicate that the DPF has been compromised and is no longer adequately trapping soot.

Understood, but I've read where Ram programmed them to use a bit more DEF because of the missing sensor.

I`ve read the same but I don't believe that to be accurate. I think that was a remnant from back when the trucks were first coming out and the general public had no idea what sensor was actually missing or what it did. The DEF system on a 2022 is fully intact and should function as any other model year. The PM sensor has no ability to detect NOx, nor would NOx levels have any bearing on the functionality of the sensor. It`s sole purpose is to identify soot in the exhaust stream and measure quantities. That data would be used to monitor the DPF only, not the DEF system. To the best of my understanding, and after extensive research on this, I believe this to be accurate. I would be happy to review any material you are referring to, as well as any criticism or corrections from someone more experienced than I.

I’ve always taken the stance of filling up at 1/2 a tank unless I’m on a longer trip then yea 1/4 is empty. I’ve seen quite a few filters damn near 100% plugged by Asphaltenes from back when I sold additives to bulk fuel consumers (fleets, school districts, larger farms, etc) so I do everything I reasonably can to prevent that. A good fuel additive pack will help keep them dissolved in suspension rather than gumming up on the filters. It’s similar varnish in an engine or oil coking inside a turbo.

Spot-on.
I’ll add that it depends on tank size too. Another reason the factory 50 gallon is a worthwhile investment.

Is this really a thing? Tank is 1/8 full and was working great yesterday after my fuel filter change but the boost is back down and starting to increase dpf levels. Should I fill her up and swap the filters out again?

Oh yea with untreated cheap bulk diesel. Typically ad packs are mixed at the station or during distribution while all the bulk fuel in a given area comes off the same racks. What a lot of folks were thinking was algae build up was actually asphaltenes in the newer HPCR equipment, most solid ad packs will help with both issues. That being said it doesn't like you have enough miles where you'd have a super contaminated tank unless you've been getting really low quality fuel. That sounds more like a boost leak issue to me rather than something fueling related.

One way to check would be to pull the separator and see if its dirty looking already. If it is I'd say something like two tanks of fuel with Primrose 406 at the clean up rate, Primrose 5007 at the 1:250 rate, or HSS Diesel Extreme at the bottle rate. That and switch up where you're getting fuel ASAP. If you do have some nastiness in your tank you might have to change filters more often until you get it cleaned out, but again at the mileage you sound to be at I wouldn't expect it to be nasty.

Well, you guys can add me to the list. It happened to me yesterday. 2022 3500 H/O Tradesman Dually from Mark Dodge, delivered mid Feb '22, 4050 miles, 274 total hours, with a high % of idle hours that I will do better about going forward. Driving down the road, message popped up for regen, regen started and very quickly after said Exhaust Filter Full, Power Reduced, See Dealer. I was still driving down the road, but it went from Regen to See Dealer within a short distance and time. Found this thread and others last night, so there's clearly an issue. Local Homestead, FL dealer service department said they had not heard about this issue, scheduled me for TWO WEEKS from now and told me not go on any long trips but that I could keep driving it. I let them know that I had seen the issue discussed on the forums and that there had been a letter circulating about the sensor and when I asked him to confirm that it's a warranty item he did confirm that. I'm going to write to RamCares Ram Chat and send all I can to the service department to get on the STAR list, but I have no intention of going through a never ending revolving door with the service department to get this dealt with. I plan to document document document. I didn't buy a brand new vehicle to be worrying about whether I can get an appointment or get an issue fully resolved. I'll do better with getting more frequent longer drives and the idle times, but I'm not going to deal with a regen every 10 hours. There's a problem and the manufacturer needs to address it and/or give an updated communication to their customers, dealers, and service departments.

If that message “Filter Full, Power Reduced, See Dealer” pops up, how serious is that? I have not seen that message yet, but I have been seeing some of the other issues discussed in this thread, such as frequent regenerations, and the DPF gauge showing the filter level increasing a lot more quickly than I would expect. We’re about to head off on a road trip from Arizona to Kansas pulling our toy hauler and I’m trying to figure out how big of an issue that would be if that message pops up when I’m halfway across the country. I know you said the dealer told you not to go on any long trips, but did they say why? If I run into this am I not going to be able to continue to pull my trailer until the issue is fixed?

 

[Bullwinkle_The_Black_Ram]

Can someone with a reader provide MAF readings at idle and highway driving 70 mph. Im getting 22 g/s and 120 g/s which seen unusually high. Using a cts3 reader.

Your road trip will actually be beneficial. Pulling the TH will keep the EGT in the range where you will be doing passive regen continuously while driving down the highway. Which will be cleaning the DPF, so you should have less chance of seeing the DPF full message.

This is true, provided everything is functioning normally. However, there are certain scenarios where this error could trigger without the DPF legitimately being full. In that instance, the only way to know for sure would be to get it scanned at the dealer and see what codes are driving the message, as well as take some readings from the onboard sensors to see if it is indeed full, or there’s something causing back pressure or a restriction.

That's about 15 lbs/min at hwy speed which seems about right for a cummins. I could check later on with my idashes, but I need to get this banks airbox out of the truck 1st since I keep throwing the EGR codes with it on. Even then my numbers won't be 100% apples to apples being an SO with the monster ram/grid heater delete on it. I'll also have to remember to drop the EZX I've been playing with down to stock (Doesn't seem to be impacting the EGR codes since I'll still pop them with it set to stock).

 

[Bullwinkle_The_Black_Ram]

Okay similar to mine 15 lbs/ min 115 g/s.

Closing my excessive regen for now. I had front end body work down 2k miles ago from a front collison. After cleaning all my sensors and running data logging using CTS3 I noticed last week my truck could actually passive regen quite effectively. Added dpf norm % tab 2 and thought it was "off" do to some algorithm bc CTS3 showed 50% soot load while the truck dpf screen showed 0. The Next day it went from 56% to 80% on the CTS3 and the truck screen went from 0 to 30%. The soot % was increasing 1% every 30 sec at warmed up cruising speed 75 mph. I backed off on boost after being disappoint and noticed the CTS3 % was decreasing smoothly. Then I got into boost again then the % shot back up. I then proceeded to drive into work at the lowest boost <2 psig lugging the motor 75 mph egt2 650 F. It dropped 15% for the first time really trying. I later tested out idling and parked it for about hour and the dpf % only went up 2% vs 24% withing 10 miles of driving in boost.

Fast forward to today and I had bought a boost tester and found it wouldn't hold 1 psig with my compressor. The shop had screwed a screw into the bottom of my intercooler and then tried to hide it under a required plastic tab. The truck could still hit 30 psig and didn't throw a code. The amount of air that was allowed to escape and no code is crazy. I can't image the about of back pressure I have been putting onto my turbo to over work to keep up. Calling warranty tomorrow and hopefully get it fixed soon.

 

[joshuaeb09]

Wow... Any shop that hid that sort of shotty work would never get a chance to put hands on my truck again. Hopefully you get it ironed out, but that leak would explain your issues for sure.

Yeah it was at an Autonation collision center so never thought i would had that issue. But I had so many issues working with their poor management of vehicle break down, parts order and timely install. I caught they charging my insurance for $2000 of parts that were never replaced. Also never fixed the KO2 tired that was damaged when I picked up the truck. It was bad management.

 

[wolfpack]

I’ve always added Pittsburgh Power Max Mileage and never see my DPF gauge move off of zero.

 

[agmund]

Any more word on this? My truck is doing a auto regen every 100 miles or so. It's a 22 model I have the banks ram air system could that be causing it? I went back to stock air box because banks one was throwing egr overflow code apparently banks is working on a module to fix the issue I did have a dpf performance code pop up too it's completely sporadic the way it fills up I even got a continue driving warning

@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.

@RamCares My truck is having this exact isssue! Regens every 30/40 miles for the last 600 miles. Dealer won’t do anything til they hear back from Chrysler. Saying it could be months. Currently at 10,400 miles total. Started around 9,500
