Does your Cummins regenerate once per tank?

Has anyone that has had a DPF replaced for excessive regens had the it cut open to see if its actually loaded with soot?

Wrong TSB, see my earlier post for the correct one. If you are implying that because one TSB didn't fix some issue, all TSB's are worthless, I'd disagree. I do wish this one was a recall and not a TSB though.

I never implied all TSBs are worthless...thats silly.

What would a recall change vs the TSB? They don't really know what to recall...considering the trucks have all the EPA required equipment, granted not working as designed completely, is probably why its a TSB not a recall is my guess...could be wrong.

Curious if this was done under warranty would Stelantis allow the dealer to do that?
I do think it would be an interesting answer, full of variables though, like when was the last regen before it was taken out.

It would certainly tell you if there is an actual issue with excessive soot...or a programming issue.

Have you read the TSB? They know very well which trucks to recall.

As far as what it would change, it would make my truck eligible for a replacement. Since I pretty much only use my truck for towing, I may not see this issue come up until the warranty and TSB have run out. I just turned over to 20K miles, coming up on 3 years. Replacing a DPF is pretty darn expensive, from what folks have posted. I'd like to not have to eat that. If they suspect all those trucks may have a defective part, they should recall and replace them all, IMO.

{sigh} No, what I meant, they have no idea how to fix it. They probably wont recall something with out some sort of "fix", may have to wait on the parts etc however if they are not readily available.

You don't have to always have to replace a DPF, they can be professionally cleaned and restored/recore to new for $500 or less. (like this place https://redeyeradiator.com/)

A recall does not make your truck automatically up for replacement. You could do a buy back now if you really feel you have a problematic truck. A buy back is generally not complicated unless you go the lemon law route.
 
I have an update on my truck. I have almost 300 miles on my odometer since the last regen. My DPF dash gauge shows 0, absolutely no reading what so ever. My driving habits have not changed and the only difference is as suggested I used Archoil 6400D in my last fill up. My last several regen cycles occurred with around 300 miles or less. The DPF gauge always showed a reading with less than 70 miles of driving. This is surprising to me and yes I am driving with the DPF gauge showing so there is no chance that I have missed anything. I am convinced that this 6400D product works as advertised.

So you think they'd issue a TSB saying replace the DPF, but they have "no idea how to fix it"?

True, and I may check into that, if the time ever comes.

In this case it would, as my truck is one that the TSB applies to. Assuming the recall would be for the same lot of VIN's.

I've done a buy back. But my truck is fine, as I pretty much only tow with it. I'm worried about down the road when it's 10-15 years old. Yes, I keep my trucks that long. RAM knows the DPF is, at the very least, suspect in my truck. They should replace it, IMO.

Well, I think it's a "best" guess since for some, it has not fixed it. In fact, between this and other forums it seems replacing the DPF has not been very successful.

Maybe they were replaced from the same bad lot of DPF's.

I would think they would specific lot numbers or even a part number change for the new DPF, I would say you can just enjoy that truck if its not having issues.

Post TSB, maybe.

A lot of folks don't start having issues until they start to roll the miles on. So it will remain a worry. I could bury my head in the sand and hope for the best, but I am a guy that takes a lot of time and effort to take very good care of all of my stuff. So burying my head is not really something I do.

Jeb,
All I will say on this subject is you cant worry about things you have no control over. Drive it and maintain per the manual.

This makes no sense, at least to me. It doesn't keep me up at night, but it's worth keeping an eye on/worrying about. It's not hard to keep track of it, and yes, I have a spreasheet for it. Maybe you'd feel differently if your truck was one of the ones listed in the TSB.

I owned a 2022, never had any issues with it other than some Uconnect issues -

Just because your truck year/build dates are on a TSB doesn't mean it will have issues. Honestly if it were me and I had to choose between a spreadsheet or spending 6K to eliminate the issue completely.

I am spending 6K, I have enough spreadsheets at work I don't want one for my truck.

I do agree with some points you make in your replies, with the exception of your last sentence, we shouldn't have to pay an extra 6 grand or any additional amount of money for that matter to rectify or "fix" something that should be a non issue. Also I feel it Shouldn't be a weight or concern either, yes these are mechanical beasts with a million moving firing electrical parts and things break or go bad sure enough.
With that said I have a question for opinion, was the whole (in general) DPF def regeneration system rushed to meet guidelines demand and keep product being produced or is it more a work in progress to continually improve.

Ya I don't think a truck owner should pay 6K to fix a known problem if there is a fix and your truck is having issues - FCA should be on the hook.

But if your truck is running as designed but the DPF is causing some concerns, OCD territory, just delete the darn thing.

Comments like this are where you’re just trolling the thread and not providing the benefit you perceive you are.

There is a huge amount of trucks operating between “as designed” and total failure. That’s where threads like this that educate folks are useful. It’s an expensive system that can be maintained far better than your recommended approach.

You say your 2022 didn’t have any issues, great! Many of them do. I’ve asked before and don’t recall being answered, but how many miles were on your 22 when you sold it? What was the average duty cycle?
