How’s it going guys
so finally got my new 22 6.7
ive got about 300 miles on it and I’ve notice it regening already
ive used FORScan to put % screen up and for the longest time it’s read 0% until yesterday about the 220-300 mile mark
it got up to 30% and by the time I was back home I noticed it was regening again and down to 10%
what’s weird is I’ve also have the auto reg gen Turned off
many ideas?
my 18 didn’t do this

why do you have the auto regen turned off on a brand new truck?
why do you have the auto regen turned off on a brand new truck?
I keep mine turned off and watch the DPF%. I typically drive less than 4 miles one way to work every day, through 6 red lights, so there is no opportunity for the truck to really even get started with a regen, let alone complete one. By keeping the Auto Regen turned off I can wait until the truck reaches 100% and then just plan a longer trip somewhere, flip it back on and actually let it complete the regen. Much better than driving it around at full all the time and never allowing it to regen. If you are driving longer distances at highway speeds everyday, I agree, it's not as much of a concern. Just depends on your driving conditions/habit.
Not sure if it matters but I turned mine off in the plain English section of FORScan and not the coded version
So, you don't turn Auto Regen on/off with Forscan. With Forscan, you are simply enabling or disabling the option to appear in your instrument cluster. So Auto Regen has actually been turned on in your truck. Another easy way to tell when Auto Regen is turned off is that every single time you crank your truck you will get a notification letting you know it is turned off and you have to hit OK to turn the notification off. If you want to turn it off, you will need to go back in with Forscan and enable the Auto Regen to show up in your instrument cluster. Then, once you enable it, you will need to go into your settings in the instrument cluster and uncheck the Auto Regen box.
and new trucks will do a few early regens as part of the ecm programming..my first one was less than 100 miles on the way back to dealer for a warranty item for an interior part..or so i was told and saw first hand on my truck. after 1k mile sit went to normal and will passive regen on highway or if i do lots of city drivign will do one at 100%

You haven’t disabled anything. You just have the DPF % enabled that’s it. If you enabled OCR (operator controlled regens) then when the DPF is full it will prompt you to do a stationary regen. Further the dash % is usually about 10-30% off of what the truck considers a full DPF.

Thats incorrect, my auto regen is turned off/disabled, so my truck won’t regen unless I turn it back on. But yes, I also have my DPF% enabled too. Auto regen and DPF% are 2 different things. When my DPF% hits 100 I get a notification that my exhaust filter is full and I need to clean it soon. If the auto regen wasn’t turned off I wouldn’t get that message and the truck would automatically go into regen once certain parameters were met. So, when I get that message, I get on the highway and turn the auto regen back on and soon after the truck regens.
As far as what “full” actually is, I have no doubt that when the dash reads 100% that it is actually 100%, but instead just a benchmark that first notifies the user that it needs to be cleaned soon. And this notification pops up because the auto regen is indeed, disabled.

what model is your truck.
your dash gauges are upside down from mine.
interesting

So essentially you have OCR enabled then disable it and turn auto regen back on when it gives you the prompt instead of doing the stationary OCR? You are doing an auto regen? Does this prevent it from doing a passive regen?
Passive regeneration occurs when exhaust gas temperature is high enough to incinerate the soot in the filter. Pulling heavy does this. In this scenario, the active regeneration is somewhat perfunctory as there's not much in the filter to incinerate, so the computer commands an active regeneration on a 500 mile interval just to make sure everything is nice a tidy in the filter. The owner's manual covers this in sufficient detail and reads that the active regen will be very short since there little to nothing to burn off.
You are confusing the various terms.
Active regen: Computer squirts diesel into the exhaust stroke to put the fuel into the DPF to incinerate the soot.
Passive regen: Hot exhaust gasses passively burn off the filter soot.
Operator commanded regen: The truck operator controls when the regeneration occurs.
Stationary regen: Sitting in your driveway (or anywhere else) with the truck doing an operator commanded regen.
I think I got all that right. You can look in the owner's manual as all of this is covered.
