Automatic Regen too often

After DPF replacement mine functioned much like yours. For about 4 months. The regen issue is getting cranky again with a couple of low mileage interval soot based regens recently. I'm still getting passive regens, but they're taking longer and I have to work the truck harder. I run 295/70/18 and they never made any difference with my regen problems. I am happy for you that your truck is functioning more or less as intended, I was happy when mine was. Something is terribly wrong with these trucks and I believe the DPF is a symptom, not a cause. I know you monitor your truck closely, and I don't want to rain on your parade, but don't be surprised if it starts getting cranky as well.
So far I've only had 24 hour regens outside that one mentioned above. On the tires I wonder if there's enough difference with what I'm running vs what you had run. I see they're about 3/4" shorter. I'm running Toyo Open Country RT.

One thing I have definitely noticed on archoil 6500 vs no archoil is that the truck seemed to have more get up and go at normal throttle with the 6500

The Archoil does seem to improve at least the regen problem a little. Between a transfer tank full of fuel and steel lumber rack I'm carrying an extra 1000# so I might not notice the throttle response.

That should be plenty of "extra weight" and work your truck is doing lugging another half ton around. I have a fiberglass camper shell thats 400 ish pounds and a deck in the bed plus additional steel tool box and tools. I wasn't likely at 1000# but 800 is a safe bet, and was still having regen issues. Despite all that weight I was still getting nearly 20mpg. The tires knocked my mpgs down, and at least appear to be getting my EGTs high enough. I don't have anything hooked up currently to read EGTs but have a Bluetooth from my ecodiesel I'm hoping to get the PIDs changed for the cummins. For now I'm just speculating they are getting high enough regularly.
 
I wondered about this too…..I went to go remove the baffle and noticed it was very different from previous years, so I decided to leave it in. I would be curious if anyone has removed and what the impact has been.

I pulled mine. Seems the same
 
I ended up giving architectural a shot after the install of my third set of injectors and another new dpf. While the check engine light seems to remain off, and I'm not seeing it go into regen near as often, I seem to be burning a lot of DEF. I recently drove it from my place in southern colorado to my parents in California, round trip was roughly 1700 miles, all highway at relatively high speed. I filled the DEF tank prior to leaving and about half way back the warning light came on with a warning that def was running low and I had to refill it. I waited until the next fuel stop (about 100 miles later), then topped off the DEF tank again. By the time I got home I was down another quarter tank.

Does this seem excessive?

To be clear....I meant archoil, not architectural

Are you filling it with a pump or jugs?

My truck will get ~700 mpg DEF empty and ~350 mpg DEF towing. If your mileage was poor due to speed it could be normal

thats alot of def man. i just topped off my def at about 1900 miles. ill keep track on this tank full and see where its at but generally my other two trucks would go 3500+ miles unloaded.

It’s inline with other DEF mpg reports for 19+ trucks.

The 19+ trucks use more DEF and less EGR, which is a god thing. The EGR crossover tube on my truck still isn’t discolored at 23K miles, where it was discolored by 5K miles on my 18 that for 1000 mpg DEF empty and 500 mpg DEF towing.

3500 miles would be about 700 mpg if you ran it empty. A lot depends on fuel mpg empty too, the less fuel you use the less DEF you’ll use. With how I use my truck it doesn’t see many easy empty straight cruise miles. Life average or 12.98 mpg diesel and 536.5 mpg DEF.

gotcha. my 21 didnt eat much def until i hooked a trailer up. then it would burn a quarter tank in a few hundred miles. my 24 i just filled the tank for the first time after 2100 miles, 350 miles of that was towing a truck on my car trailer, or the dump trailer to the dump. but the dealer didnt fill my def tank when i bought it minus 1 gallon they had in stock. so ill see what i get on this full tank.

Mileage wasn't bad as far as diesel itself. Truck wasn't towing or loaded down, si that was just over 18mpg average. I would imagine running highway the whole time it wouldn't have clogged up or regened as often.

As far as def goes, before the trip it was filled up to the top with jugs and while driving back at the pump. Both times the meter read full and I literally could not have put more in without having it slosh out.

It seemed excessive and never was a problem on previous trips.

It was nice however not to have a check engine light come on.....yet at least.
 
Possible fix if anyone is having issues with their dealers still, TSB - 25-005-24 dated September 27, 2024. Have your dealers check, and if you’re having this issue and you’re within the warranty they will replace DPF.

Doesn’t cover a very wide span in production dates. 8/1/22-5/1/23. Mine was built 6/22. Maybe they are going to work their way backwards.

Wouldn't you know it, mine has a build date of 8/2022 and they replaced the DPF (and MAF and paid for several months of rental). If all was added together, it was about $3600 in rental truck fees plus per an email I received from Ram (trying to sell an extended warranty)the repairs were about $3300. At a retail level, their (or parts supplier) screw up cost nearly $7k

Lol amateur numbers...... I am well over that in just rentals probably tipping the scales to $100k..... they do replace stuff under warranty but it takes diagnostics to get it replaced.
