No thats a really fast regen that would not do much

depends. if its one of the regens that happens every 24 hours of engine time and your gauge was at zero already then yes, 5 min is pretty normal. If you are nearly full and only have 5 min of regen then you arent making progress to clear the filter.

Up until i hit 50k all my regens have been with nothing on the gauge and taken at a minimum 20 mins…

Mine have all been the same so far though less miles on the truck. Every one at 24 hours and gauge at zero. They always take about 15 to 20 minutes at highway speed. If I am on a short in town run when a regen starts, I will get on the freeway and go a couple of exits and back just to get it over with. I know Ram says that is not necessary and yes it wastes fuel, but with this problematic system, I just feel better getting it over at a steady high temp. Rather than letting it start and stop multiple times over a week with short in town trips.

My last regen was the first regen with a reading it was over 3/8s. My run to work is 7 mins on the highway and it took 2 runs there and back over a couple of days it was back to zero each time i parked the gauge was lower. So no need to run extra on the highway but im sure it does not hurt

I do the same. My on the highway regens last 20 miles start to finish. My gauge has never gone off zero but shows it in regen. I monitor regens and soo levels with an Edge CTS3.

I guess it varies! My last regen was with 14k miles, had been towing for the previous 500+ miles and it only regened for a few min. I did not time it, but it was certainly well under 20 min. When my DPF filter is above 50% is when I have the 20-ish min regens. And the majority of my driving is without a trailer in tow.

Too bad there isn't a default indicator when it goes into regen, vs having to keep the display on the DPF screen. I like having other things on my display.

Cant confirm this, as my DPF hasn't gotten this high yet, but I believe that once you hit 80%, you will get a pop-up regardless of what info screen you are on and a message to "keep driving" so the regen can complete. Personally, I'd rather monitor and manage the DPF/plan longer drives instead of waiting until its that high and required. With my luck id be late for something already and have to stay on the highway an extra 30min.

Several times that I've looked at the DPF gauge, it is always on zero. I was lucky enough to catch it going into regen when I had that screen pulled up.

Here's what I believe is happening.
The truck will regen if the soot level hits 80% before 25 hours have passed, and always every 25 hours.
An 80% regen will always take the 20 minutes or 20 miles
If there is no 80% regen it will regen at 25 hours and take whatever time or miles according to the soot level at that time.
If there is an 80% regen let's say at 20 hours, it will also regen at 25 hours regardless of soot level and may only take the 5 or 6 minutes as mentioned.
I could be totally wrong, but all that I have read and what's being reported makes me think the above.

 

[kennelpj]

I'm in agreement!

I wish I could get to 80% soot level on my 2022 SO, it hits 48% and within a few miles boom it will go into regen no matter what the hours are and I have seen this multiple times. See my regen rate as of late and I have been doing 70% hwy driving.

I'm currently waiting on Differential Pressure Sensor 68312096AB and the 2 Differential Pressure Hoses 68376348AB upstream and 68376349AC downstream to install to see if this fixes my regen issue since the dealer was of no use to me.

I see you do a ton of idling is that in high idle? If not i would highly recommend it

No I don't do high idle, most of that maybe sitting at offramps at freeway exits that take along time to change around PDX since the greenies want you to sit in traffic to push their green agenda and not build larger freeway's. as they have not made a new freeway in Portland area since 1980 and another 1 million people moved in since then.

I start the truck let it warm for 1-2 minutes then drive to the hwy. Since my CEL early July and this popped up at 6627 miles Exhaust Filter Full See Dealer right before I moved back from Wisconsin to Washington I was on the standard 24 hour regen. Since that event it has gone into hyper regen and have been keeping record when it goes into regens. I don't know if the -20° winter weather in Wisconsin had something to do with it IDK. I wish it would give me another CEL to go to the dealer to look at.

 

[BighornHDRam]

I wish a tune was available for the 2022 trucks, the only reason I ordered a 2022 was I was sick of the CP4 issue and 2 pump replacements I went thru and the headaches with star over it and now this. I'm considering getting a Ford Transit 250 at this moment if this issue continues.

when you went to the dealer for the DPF full message, what was the resolution and cost? Haven't gotten to that point (yet) but am curious to that process.

I think I agree with this. Except on mine I have had 6 regens. Every one of them has happened on the 24 hour interval, not 25. Odd that there might be this small difference. My last one started at 144 hours.

There was an older thread here from last year sometime that discussed what the computer might consider idle time and why different trucks report such large differences in idle time. My truck is now at 46 hours idle and 99 drive. There is no way this is correct. I tow the TT almost exclusively with this truck. So even though I do idle when hooking up or backing into a campsite, (and some of that is high idle), generally I hook up and then drive many towing miles and hours to the destination. The truck is never used as a daily driver. Also almost never used around town unless I need to take the utility trailer to the landfill. Almost all of my miles are distance towing miles except for the 700-mile highway trip home from the dealer. I just can't see why my truck would report 46% idle time. Makes no sense but there were others in that thread that reported similar. But even with all that reported idle time, the only regens I have had have been on the 24-hour marks.

I have read 25 and 24 hours. However, there are more posting like you within 24 hours. I'm inclined to believe 24 hours is a more accurate number. Thanks, I'll start using 24
