So who else has the WORST regen timing?

I figured I was close to completing my last 24 hour regen when we arrived home from a short towing trip. I left the truck in drive even and when my wife opened the door to get out, the regen stopped! Arrgghh...

Drove a block up and it restarted, went out of the neighborhood and the long way around back in, maybe 3 miles, and it finished.
That’s how mine did. I didn’t realize her opening the door would stop it. When she got out, it stopped so I just cut it off and got out too. Started again about a half mile after we got back under way and finished about 3 miles total later.
I guess I should have made her climb out the window.
 
The inconsistency in how the system operates is truly maddening.

Some soot based regens are pretty inconsistent, but once a regen starts the trucks are consistent on how the regen operates IME. Soot based and time based regens do act differently.

The inconsistent part is watching my regens go from consistent 24hrs, to 12-13 hours, with no change in driving habits or fuel source. 12-13 hours isn’t horrible, but I’d like to figure the reasoning at least.

They are incredibly sensitive, and difficult to figure out. Sadly for me, having a heavy trailer attached 24/7 just isn’t an option either. If the owners manual stated “must be hauling heavy weight for DPF to function properly” I’d have never bought the truck.

Weather changes seem to be a factor too.

If your diving doesn’t include decent passive regen then it’s not surprising to go from 24 to soot based, and I’d guess after a 12-13 hour regen with no change the next one will be soot based too. Soot based regens also don’t seem to be nearly effective enough so the truck gets caught in a cycle if you don’t break it.

Haven't had or seen a regen on our 2024 Ram 3500 Cummins in the nearly year and 11K miles since purchasing it new. It's not hauling heavy weight all of the time. Driving from our home onto our highway there's a very long continuous stretch of downgrade with up to a 10% gradient. I use the exhaust brake to hold it back. No stop signs or traffic lights for 30 miles. Seldom sits in any traffic or at a stop light for long. Different driving habits might be why the regen is not an issue.

Unless you average over 450 mph you’ve had multiple regens, probably 10-15 of them unless you do a lot of really slow driving.

If you don’t monitor them it’s impossible to know much about your trucks regen habits. It’s very possible to be having soot based regens and the wrong duty cycle for the emissions without setting a regen CEL.

I assure you that you have had multiple time based regens.

I hope so.

Our Stellantis shark fin antenna was not functioning for the past 11 months shortly after our purchase in Montrose, Colorado. Thought it was poor cell phone coverage. Required a trip to the dealership which isn't close. Not sure if it's related. Time for regen is probably based on engine hours. Finally got it to a Ram dealership in Laramie, Wyoming earlier this month. It took 8 days (7 of them working days) to repair due to the part had to be shipped in. Now Stellantis can track our whereabouts.
 
The first few months I owned my truck, I missed multiple regen events from simply not having the EVIC on the DPF page. When towing I would keep it on the temperature page to keep up with how everything was doing and completely missed several regen events. Got the ScanGauge and now I can watch both and know when it’s going to regen and keep up with the EGTS and know when it passively regens. Here lately the EGTS have been running a little lower than usual but it has cooled down some.

Every time the truck leaves the house, it has 16 miles of 75mph to and from. Passive regen works great for months at a time, and goes to hell for just as many.

75 was hit and miss for me on decent passive regen depending on weather and road conditions. 80+ was usually a good speed.

I just have a sneaking suspicion that I’m lucky enough to have the 2022MY blues, and I should just be thankful it’s not going into regen every 50 miles.

I’d love to work with a dealer to find a solution, but that’s just never gonna happen with the quality of dealer service in my area. It’s gonna be sell it or weight loss once the warranty is up.

Weather / climate seemed to be the most defining factor for my 2022. I could achieve 24 hour regeneration cycles very consistently when operating in the cooler months of the year (October to May) and then from June to September it would struggle to achieve more than 12 hours. Even with Archoil the warmer months were a struggle and the truck saw very repetitive drive cycles 12 months out of the year, with only intermittent towing. IMG_3870.jpeg

Is your 2024 equipped with the fully digital instrument cluster?

Highly doubt that my Tradesman has anything fully equipped except for the emissions.

Update. No. It doesn't have this display available at all...

Since my 4500 mile road trip (truck was empty for the whole trip ) back in mid May the truck has been even better about regens, my EVIC DPF dash gage has not been going up between 24 hr regens :), so I started taking it out about every 5-6 weeks on a 3 hour round trip drive to the Oregon coast for no reason other then to keep the DPF happy and I'm surprised being the top speed on the trip is 65 MPH in a 1-1.25 mile passing lane, that speed is if your lucky and you have no major traffic keeping you at 45-50 MPH when you get to the short passing lanes. I also have to say my truck seeing 24 regens is thanks to Archoil products 6400-D and 6500....
 
Not trying to derail but anybody else hear the rumor about Ford testing factory deleted trucks?
 
can a new truck go into a regen cycle with under 700 miles? I noticed this morning the instant fuel mileage at 55 MPH went from around 19-20 to 15 and almost stuck there. At home, in the garage, I noticed a burning smell. How can I tell for sure that is what it is doing?

Absolutely, how many engine hours?

The truck will regen based on soot loading or engine hours, not miles.

Mine was the same, new with only about 800 miles it smelled like burning plastic, and you could see the fuel consumption increased.
Hours were right on 24 .
