Automatic Regen too often

56ram2500 said:
A regen 4 times in 270 miles is not acceptable nor is it normal, its there way of saying we don't know how to fix it or what the problem is an its just tuff luck for you....

Yeah I’m getting that impression. I don’t think 1 regen in that amount of miles would be acceptable let alone 4
 
Don’t pay too much attention to miles between regens, concentrate on hours. Unless you idle a lot that too few of hours for sure.

Did the dealer do the DPF reset in the ECM that’s required with a new DPF?

Also, the paper towel method is still a good one for fuel dilution but it’s also easy to see with an increasing oil level.

I don’t know if they reset the ECU from the DPF installed. I would hope they would if required but being in the dealer industry I can also understand if it got missed. I didn’t check my idle hours but I from trucks I was looking at before I purchased this one compared to what this was, the numbers on my truck were very low as it was a 1 owner truck. I try and limit idle time and when I do I use the high idle feature.

Nevertheless, the dealer gave me a loaner 2025 2500 HO with 10 miles on it so they can take as long as they need. Apparently they opened a star case so now it’s just waiting on ram to walk them through what needs to be done.
 
Quick update. The dealer called me and said they tried to do a hard reset per the RAM, and that didn't work. They are replacing the air filter (I just installed the correct filter 500 miles ago) and swapping out the MAF. From there, they will be putting 100 miles on the truck and seeing if that fixes the issue. I have a Thuren leveling kit in the garage just waiting for the truck to get home so I am ready to get my truck back. The 25 loaner truck is pretty sweet, but they have done everything to remove the turbo noise so its not as fun to drive .
 
I had the DPF totally block (40k miles) and was towed to the dealer. They used their software and did a DPF regen/calibrate. This is usually done when a new DPF is fitted. It ran the truck at reves for probably 30 minutes. When finished it showed zero. They said the issue was contaminated DEF so this was drained and refilled. No problems since then and it now has over 100k on the ODO.

Dont know if this is available with alphaobd. Would be good to know.
 
I have been afraid I was masking any DPF issue because I almost always just use my '22 for towing. We are away from home for a month and or only "grocery getter" while here is the Ram. We pulled the bass boat up here with it. I was used to 23 hours between regens. The last 3 look like this:

So it appears, like so many other '22 6.7 owners, I have the DPF bug. When I get home, I'm going to try to get them to honor the TSB for this. I haven't thrown the CE code that I know of though. Makes me wish I'd never gotten rid of my '18 6.7.

Do you have the September 2022 build date? My dpf got replaced before the tsb came out, but was regening every 30-50 miles

Slight update that might help others - with the warmer weather I started to see my regens creep up after nothing but 24 hour regens (except 3 hiccups) since August last year when I picked up the truck from the dealer after they had it for several months trying to fix it. With that said, I ran 6400d about every 3300 miles. Which was about every 3 regens. Except those 3 hiccups that started with much warmer weather. Since then I've run the 6500 a little hot - 6 oz to an average of 24-25 gallon fill up. It has since been back on 24 hour regens. While I agree there may be a programming error (aside from the 09/2022 build date tsb) I'm mostly of the opinion the programming is for 50 cetane but most fuel is closer to 40. The cetane boost likely creates a cleaner burn as well as higher EGTs, however someone with a scan tool could confirm that as I dont have one for this truck.

What is the paper towel method?

Based on what I 've been told very short city stop & go driving with trips under 10 miles one way is very hard on the emissions system aka DPF, even more so if your using B-20 full time, it was suggested to limit B20 use for all hwy driving, also understand it that Ram has decided that if you get 350+miles between regens then your having normal DPF regens :confused:....

The TSB covers more than trucks built in 9/22. Mine was built in 8/22.
This bulletin applies to vehicles built on or after August 01, 2022 (MDH
0801XX) and on or before May 01, 2023 (MDH 0501XX) equipped with a
6.7L I6 Cummins Turbo Diesel Engine (Sales Codes ETM or ETL).

Yes, I'm fully aware of that. But they have a TSB to address excessive regens in many of the '22 trucks. I'm hoping I qualify. Speculation is that they had a bad batch of DPF's.

I have not paid attention to what kind of diesel I've been using here in Northern Wisc. I doubt there is any choice though.

If you use fuel with more than 5% Bio you increase the chances you will need to do a lot more Hwy miles to help keep the soot load down in the DP...
 
Got the call, my truck was ready to get picked up. Speaking with the advisor, she states that the tech replaced the MAF and the filter and put 60 miles on the truck. In the 60 miles the there was no regens so they are going to close out the star case. Picked the truck up, and all appears well. What pissed me off, in "60 miles," they blew through 3/4 tank of diesel and gave me back the truck with 30 miles left in the tank. Looking at the MPG counter, it shows 11mpg. That's what I get when I tow my travel trailer. I assume they beat it like it owed them lunch money to get the results they needed, all while I made sure the truck I brought back had the exact amount of diesel as I got it with.

Did you check your idle hours?

I wonder if they did a stationary de-soot.

My guess it was the MAF relearn procedure. I'm quoting from memory but it's something like drive for 20 minutes at a constant rpm then shut the truck down for 20 minutes. Then do that 2 more times. Likely that is where the 60 miles came from. Since most highways don't have stop lights, that is where the mechanic or lotboy usually do their drives for this.

That would make sense. With that said drove it to work today and the DPF jumped to 25% by the time I got to work. I have a 25 mile commute that’s a mix of bumper to bumper and normal driving. My guess is on the way home it’s going to be into a regen.

Having gone through what you have, I hope it gets solved soon. Ram had my truck for almost 4 months last year...
