Automatic Regen too often

[OLEJOE]

I’ve always noticed my DPF inlet and outlet pressure sensor delta to be above 1.3 or so when I go into a soot based regen, yours is not showing much difference and your at 6g of soot. Of course my screen shot is just after it went into a regen. Maybe something to look at.

I have noticed on my SG that the dp goes up during a regen. I also noticed after going to the larger tire size that the EGT’s run closer to 700* at 80 mph. Speed limit on I-49 is 75 so I was able to maintain 80 mph for about an hour and it really made a difference.

Yeah, my 18 was a very different truck when it came to regens too.

The duty cycle doesn’t sound like it very passive regen friendly, at least that wouldn’t have been for my ‘22. Most my driving is on 50mph and lower roads, but I was able to maintain my avg mph in the low-mid 30’s. A week of driving to/from work was all the truck would need to switch from time based to soot bases regens, regardless of how much I had towed the weekend before.

I’d probably give a tank of archoil 6400d a try and then just monitor the regens. If they start getting shorter and shorter let them, wait for the CEL and take it in for the DPF TSB.

Actually this tank has the 6400d in it and I've been using R99 fuel as much as possible, there is some B5 in this tank but mostly R99.
My truck was built out of the DPF TSB window (May '22) so I don't think that would apply to mine, i also have the monster ram so I'm sure they would say that is the issue.
Before the last camping trip I was noticing the soot loading and I did check the system for boost leaks and there was none. I pressurized the system to 40psi and sprayed everything with soapy water and didn't find or hear any leaks.
After I get back from this next camping trip this weekend I may try the MAF reset procedure and see if it helps any.

How long have you been running the Monster Ram ? Mine is a June 22 build. I noticed a MAF relearn in JScan but I don’t know if it’s actually anything other than the instructions on how to do it.
It says for after replacing the MAF.

Monster ram has been on for a few months, I didn't notice any change in soot loading at that time.
AFAIK, there is no scan tool reset of the MAF, you have to do the drive 10 minutes at 2600 rpm, then pull over and sit key off for 10 minutes then do that procedure 3 more times

Obd link mx+, you can customize the dashboard on the app.

What app ?

The OBDLink brand readers have an app.

The perform service message is more than likely to change your CCV.. Triggers off mileage / time.
Once CCV is changed to reset it... turn the ignition to the ON position without starting the engine, press the brake pedal twice, slowly press the accelerator pedal all the way down twice within 10 seconds, and then turn the ignition off. After completing these steps, start the engine to see if the message has been cleared

Hi everyone. I have a 2019 Cummins tradesman. I got the Perform Service message at 67,500 miles. I changed the CCV filter and reset the message. Then at 75,000 miles exactly, I got the same message again. I’m guessing this is because Ram changed the CCV service interval but didn’t update the software.

The internet says: “For a Ram with a 6.7L Cummins engine, the crankcase ventilation (CCV) filter should be changed at 75,000 miles, as indicated by the service message on the vehicle's console. This is consistent with the maintenance schedule for 2019 and newer models. For older 2007.5-2018 models, the interval is 67,500 miles.”

I’m wondering if anyone here knows why I got the message twice. Is it just an error, or is a different service required?

Thanks in advance.

Where did you purchase the replacement CCV filter that you installed at 67,500 miles?

 

[Andrew2019]

I bought it from Geno’s. Just checked my receipt to confirm it was the Mopar CCV filter.

Since you have already swapped it out and with a quality filter, I would just reset it again and see what happens.

 

[mbarber84]

Yeah it’s definitely legit if it came from Geno’s.
I’m wondering if your prior CCV filter just happened to fill up at 67,500 and you got the previous notification due to that, rather than the 75k reminder interval.

What engine oil do you use?

Chevron Delo Full Synthetic Motor Oil 5W-40

Not sure what happened here. I pasted in my oil type above. On my end it looks like it is part of your post.

Anyway, I use the Chevron Delo full syn 5-40. I can change the CCV again, but it seems very early to me. What do you think?

Thank you for your feedback.

I find it highly unlikely that you’d saturate a CCV filter in 7500 miles.

If you’re not running with excessively high oil levels, and aren’t suffering from weapons-grade blow by, I’d just reset the message and move on with life.

Joined the P2459 club this week. 2022 2500 with 37k miles.

Saw it was coming. Miles between last several regens was 73-65-60-58. Check engine light came on when the next regen started.

Going to pull an oil sample this weekend and send to get tested. Haven’t been checking oil level as driveway is too steep to get good reading.

Will contact dealer next week to see when I can get it in for service and see what they’ll do. Hoping a new DPF is in the playbook and doesn’t take too much to get to that point.

Dropped the truck at dealer today.

I checked the oil over the weekend after getting it level and letting it sit 30mins. The result wasn’t good. Was onto the cable part of the dipstick. I certainly didn’t overfill it at last oil change so the frequent regens are definitely increasing the oil level. I mentioned this to the service writer as well. Hoping they have some details by Friday.

Also, waiting for my oil 2 analyses to come back.

Curious as to your driving habits.

Curious as to your driving habits.

Short trips around town. Occasionally a highway trip. Tow 10k trailer 4-5 times a year. 37,227 for 29.5mph avg. 25% idle time. I don’t let it idle but cumulatively it is what it is.



Here’s the oil analyses from Horizon. Not good. Only 7k on this oil change. I didn't use them for the last oil change so there’s a gap in the history listed.

 

[Trash Panda]

Short trips around town without adequate high loading time like interstate driving & towing is a recipe for a plugged DPF and/or frequent regens.

That being said, it sounds like you’re dealing with a problem in the system itself on top of it all.

Unfortunately you have the wrong tool for the job, any diesel in the last 15-20 years isn't the right engine choice.

I completely knew that going in. Didn’t expect it to be THIS bad though. Obviously Ram using engine injectors for regen was an awful idea. Guess they got rid of those who made that decision and finally changed to add the 7th injector downstream.

My 2006 5.9 had 175k when I traded it in and it never had any issues with my driving habits. Averaged 15mpg too. Once “they” added the emissions and handicapped diesels, that’s when the problems started.

That will help with fuel dilution, but not frequent regen issues from the duty cycle.

Apples and oranges unfortunately, emissions really have caused a lot of problems.
