Automatic Regen too often

[OLEJOE]

Well, I think my good regen times are over. The DPF replacement from last April seemed to have my truck operating 'normally' with great passive and 24 hr regens. The Archoil treatments seemed to help as well. I've now had 2 soot based regens in less than 8 engine hours, with the one this morning taking almost 40 minutes of hard mountain driving. It was nice while it lasted.

I’m sorry to hear that. It’s so frustrating that nothing has been resolved with these issues after this amount of time. These emission systems are so complex with so many different systems and components and it only takes one piece out of kilter to throw the whole system off.

What’s even more aggravating is the fact that it might only be a minor tune adjustment might clear all of these problems up but is not possible with the encryption they’ve used.

How many miles since the DPF was replaced?

Shut the truck off this morning at 7:13am at mileage 48,821.9 and a dash gauge showing 25%

Started it back up at 2:35pm at the same mileage and the reading is higher now, showing 37.5% on the dash gauge lol

No passive regeneration on the way home.

I think it’s impossible to nail down a pattern unless you’re towing all the time. That happens to me all the time. I will get what appears to be some consistency with soot loading and on the very same trip that I just had some passive regeneration occur, I get soot build up and the gauge never goes back down indicating zero passive regeneration. I do however experience something similar to you, on my commute when I know there has got to be some passive regeneration going on, I get home and the gauge has not moved. Turn it off and the next day get in and start it up, gauge has dropped down but it doesn’t always behave that way. Very strange.

I’ve noticed the same thing with mine. I think the gauge is reading higher when shut down simply because of the differential pressure while driving. Then when it’s restarted cold, the pressure hasn’t been as high so the differential pressure is lower momentarily. Mine often jumps back up to where it was when shutdown after driving a little.

How many miles since the DPF was replaced?

I'm just guessing right now, but less than 10K

 

[Blackpowder]

Just slightly off topic, but I ran across this 2022 for sale and one of the add pics shows a loaded DPF screen! Think I would steer clear of this one.

Dealerships are shameless, greedy predators.

Well, my truck is looking like it's going to do a soot load regen soon, it's at about 88% on the regen PID, the dpf gauge is one before 50% and I'm at about 13hrs since the last regen, BUT I was towing the last part of that, so when I got back from the camping trip the estimated soot load was 0 and since then I've been driving it like I always do and I've driven about 120 miles and it went from nothing in the dpf to a almost soot load regen. I am running the 2oz to 10gal of archoil also.
I really hope they figure out why these are doing this and have a software update to help soot loading in warm weather. The older trucks had no issues with the seasons, there is no reason why these can too

Agreed. I wonder if they already know what the "fix" is, but can't roll it out for fear of running afoul of some EPA, etc rule.

You would think they would want it running efficiently regardless of temperature. From my understanding, any changes to the emissions strategy have to be cleared by the EPA, so maybe that’s where the hold up is. If I had a nickel for every frequent regen truck I’ve seen reported in the past few months, I’d be a few months ahead on truck payments. There are currently 128 trucks on my tracking spreadsheet. Just haven’t had the free time to update it.

And how many more that don’t know they are having trouble or are towing daily and not seeing it ? Or haven’t had a problem YET.

My guess?….LOTS of them.

I encounter people almost every day that have no idea what the DPF screen is, or that it’s even there. And also usually have no idea what regeneration means.

 

[Ramsomair]

Yep, my 2022 with 80,000 miles goes into regen almost every day now for the past 2 weeks. All 70+mph running on the highway.

While it does border on conspiracy theory, much of what I've heard from sources I trust, indicates their primary driver is indeed getting diesel trucks off the road. They don't care about efficiency, longevity, or proper operation so long as the evil NOX and PM are kept in check. Much like many government agencies - We're letting the lunatics run the asylum IMO. Specifically in the case of our trucks I have heard from more than one source that the EPA pressured cummins to run them richer and use more EGR over spraying more DEF "it has a DPF"... Yea a DPF that the things are wrecking under certain operating conditions.

They really don't care about the impact to working people or the effect they're having on inflation - If you don't think this crap drives food inflation go talk to any farmer that's had to deal with modern emissions on equipment failing during harvest, planting, etc. We need balance and solutions that actually work and keep these trucks on the road working rather than nonsensical solutions driven by ideology over pragmatism.

As a farmer myself, who has dealt with malfunctioning emissions equipment during the harvest and hay making seasons, I can wholeheartedly confirm that it becomes a significant and detrimental issue. A machine that goes down isn’t making money or getting work done. Both of which need to happen 24/7/365 in farming.

I try not to play the conspiracy theory game too much, but I would totally agree that the powers that be, in places on high, have demonstrated a clear contempt for diesel vehicles and an almost maniacal obsession with their continued restriction. That being said, I think the vast majority of the emissions issues we face come down to one of only three things, none of which is conspiracy. These are:

1. Operator habits and maintenance (or a lack thereof)

2. Software, programming, and tuning management

3. Component quality and assembly quality control

In no particular order. The latter of the two being predominantly driven by corporate greed and an interest in stockholders shares rather than a commitment to the customer and end user.

As for driver habits and maintenance, much of that comes down to a lack of understanding and knowledge. Manufacturers, especially in the automotive sector, do very little to properly inform or educate owners of best practices for both maintenance and operating these systems

Not to derail anything, I just made a drive in my truck that hasn’t been driven for the last week. Put about 70 miles on it and had a chance to get it to good operating temperature. With speed in the 75 mph range, EGT’s would run just around 600 degrees. To get them in the 650-660 degree range required 85-90 mph cruising. Can you imagine what a highway patrol officers face would look like if I told him/her “I was trying to get my truck to regen and clean out my DPF”.

3rd trip to the dealer with no fix yet. Here's the list of parts so far differential pressure sensor x2, maf sensor, correct air filter, new particle matter sensor and a reflash of the pcm.

This week I pressure tested the intake system and clamped off the CCV line for the test. No leaks at 20psi of shop air like the test states. Next I pressure tested my exhaust and no leaks from the down tube to the cats. All sensors and lines passed. Mpg is decent. 17 in town and 20-22 on the highway on the dream o meter on the dash calculating it.


I'm literally pulling my hair out with this truck. Constant regens and building soot. Here's my graph from a 10mile drive on the highway. Started at 2Grams and spiked to 3grams in a matter of minutes. Pulled off on to the exit ramp and spiked to 4 grams. If I drive in town only I build no soot. Driving on the highway is the only time I build soot in the dpf.


Does anyone have a list of confirmed fixes on these trucks?

Is it worth contacting ram cares?

I find mine also builds soot faster while driving on the highway over 60mph while climbing a grade of a few miles, flat highway doesn't build much. Surprisingly driving around town doesn't build as much, or it actually does but it can't really measure it properly until you get the speed and load up a bit, then it recalculates and gives the soot load swings

That sucks you were almost to point of my truck. Good thing you have everything documented from before.
