Cluster messaging regarding DPF

I have a 2022 2500 and had an issue with my DPF recently. At 59000 miles I got the cluster message "exhaust filter full reduced power see dealer" (sort of like that). Brought it in and their only response was it needs to be replaced and since I would out of emissions warranty came out of my pocket. Didn't seem right at 59000 miles but no matter what road I took same response, DPF needs to be replaced. Long story short had it replaced. During my driving up to the 59000 I would randomly get the message about the active rengen, continue driving with a "ding".

Started watching my DPF guage more... only 5 driving hours in and my guage shows between 25 and 50% full (since 4 divisions I am assuming that is what it is). Got a message on my cluster while in the DPF screen that stated active regen in process, but no statement to continue driving and no ding. Went to the speedo guage to see if the message would show but it didn't. Drove the truck for about 20-30 more minutes and message went away and the DPF is now 0%.

Question is... are the two messages the same? Since I did not watch the DPF previously did I just not see this message before? Why does one say keep driving and the other does not? Also, 5 hours on a brand new DPF seems early to have a regen

Also, went into my user manual and none of the messages listed in the manual are what I get!!! What the heck
 
I have a 2022 as well with 30K. I’ve never gotten the first one and I average 800mi between regens as it’s dedicated to mostly highway and towing my fifth wheel.

As to the second one, I find the dpf gauge to be utterly worthless. I have a Banks iDash cluster to keep track of things and I’ve had the Banks showing 90% to regen start and the dpf gauge show minimal or zero. My dpf gauge has never gone over the 50% mark since I’ve owned the truck.

Doesn’t the DPF fall under the 8/80K emissions warranty?
 
“Active regen in progress” is either a soot loading, or time triggered regen.

The “keep driving” message is when the driving habits have not been able to generate enough heat in the active regen to clean out the DPF effectively. The two are related, but not the same.
 
Just had the DPF replaced and only have 5 hours of driving.... so guessing not time triggered, not sure how I could have enough soot loading in 5 hours unless that was always the case and I just didn't see it because I was not on the DPF screen

My 2022 has been exhibiting rapid DPF loading as well.

Just had a 5 hour regen cycle, actually.
 
Really just wondering now... since I never left it on the DPF screen that this is actually normal and was happening in the background (didn't get the "ding" and more aggressive message), and that if I failed active many times would get the other warning?
 
Everything you’re experiencing is “Normal”

If you do know the truck is in regen, I’d definitely advise driving it until the regen is complete, and to avoid slow speeds if possible. Stopping mid regen and being stuck in slow speeds is a recipe to receive the “continue driving” message on the evic.
 
There are two messages:

“Automatic exhaust system regeneration in progress”

This message is the “normal” message which only appears on the DPF page within the EViC. When the truck engages active regen mode, the DPF gauge will temporarily disappear and be replaced by this message. When regen completes, the message goes away and the DPF gauge will return.

The other message is what’s known as an “intervention strategy” message. It reads:

“Automatic exhaust system regeneration in process continue driving”

This message will appear on the EViC as a “pop-up” regardless of which screen or page you are currently viewing, and is accompanied by an audible “ding” or “chime” from the instrument cluster. When the intervention strategy message pops up, it is usually because the operator has repeatedly short-tripped the truck, or interrupted the normal regeneration cycles to the point the filter is higher than the 50% trigger capacity for normal routine regeneration. (These trucks initiate active regen at 50% of DPF capacity OR every 24 engine hours…whichever one happens first )

Being that it’s a 2022, I’m not surprised to hear it has DPF issues. Has the truck ever activated the check engine light due to a P2459 code?

Emissions warranty is 5yrs or 50k miles for most trucks, but can also be 7yr / 70k miles for trucks sold and registered in states that follow CARB regulations (called the California emissions warranty)

Also, if your truck had the Y43 recall completed, you automatically get a 1 year unlimited mileage warranty on the DPF from the date the recall was completed.
 
I have not had the CEL due to P2459... yeah I am a non-carb state so 50k was for me. I will check but not aware that I have had the U43 recall. Is the duration expected? Only 5 driving hours?

832 avg between regens, 841 since the most recent regen. 20 hours since most recent regen.

And, as you can see I am 84% to my next regen and my dpf gauge reads zero.

5 engine hours and already requiring a regen cycle would be very short, and not a great sign. Did the dealership perform a soot load verification test before and / or after the DPF was replaced.

I cringe every time I see a dealership jump right to “replace the DPF” because more often than not, the reason for the P242F (filter full) code is an upstream issue or a lack of adequate drive cycles / work load and the DPF itself is merely a casualty.

Tossing a DPF on the truck without fully confirming proper operation of all upstream systems is a quick way to have the truck return with the same symptoms

did you get just one Banks or multiple? Are you able to get enough data?

JFYI You can have up to 8 PIDs show on one view on the iDash at one time. Plus have multiple gauge screens. So lots can be tracked although 8 is the limit on any one screen. On mine I find one screen gauge with 8 fields monitors more than I need.

Mine has had the ding and aggressive messaging once likely the result of some bad fuel that time. Otherwise all 24 hour regens with no dinging and messaging, runs in background.

The new iDash pro can connect to your smart phone via blue tooth and update automatically to the latest software, as well as it allows you to “build” your pages much more quickly than using the buttons on the unit itself. Can swipe left and right on your smart phone and change the display on the actual iDash unit. It’s a nice update over previous models.

That’s because you have zero soot load and are 20hrs into a 24hrs time based regeneration. Your normalized trigger for the Dpf regeneration is computer calculated using hrs since last active regeneration and zero soot load. The closer you get to 24hrs with good passive regeneration the higher the percentage will be.

I fought this every which way I could... I am even a Chrysler retiree and tried to go through my contacts no help at all. Even tried a different dealership and got the same answer. Once I got the exhaust filter full, reduced power see dealer it appears the "script" is to replace. Tried to get customer care involved. Only thing that is good is that I have a 2 year unlimited warranty on the replaced part. It is scary how little some know and try to act like an expert, one of the tech's even asked me how much DEF I was going through!!!
