Does your Cummins regenerate once per tank?

[AH64ID]

I noticed the shorter time, mileage regen frequency after bringing the truck in to the dealer for warranty recalls.
According to this attachment I need to confirm that I have the correct MAF sensor.

Which recalls?

Give archoil 6400d a try, it really does a great job cleaning DPF’s.

I've never used 6400, only because I haven't had to so far. I've used 6500 at the "performance dose" since the first fill up after I burned thru all my free dealership fuel. Only 4400 mi on the rig but the DPF, according to my gauges and regen frequency (right at the 25 hr mark every single time), is squeaky-clean. I'm going to contribute that cleanliness, at least partially, to my using Archoil 6500. A good amount of those 4400 miles are around-town stuff nowhere near passive regen temps and still, so far, not a tick on my DPF gauge (I probably just jinxed myself). After the most recent regen last week (while towing on the highway thankfully-- which produced EGT3 temps of over 1000 degrees) my Banks monitor showed DPF @ 3%. Of course, if I continue driving, it will creep up to about 45% and thats where it sits until I shut the truck down or until the iDash starts showing time-based % instead of soot load %.

I second that!! Trying to figure out what to watch to catch it, rpms, temp, fuel mileage.

Well, my issue is I dont care to know.

Dealer had my truck for two full days plus 3 hours this morning. I was told that there were no active or stored trouble codes.
They completed 2 regens (Forced?) the second this morning that took 80 minutes.
After the second regen I was told the truck was driven for 20 miles and the DPF showed 0%
I drove it on the freeway after picking it up and it now has 55 miles on it and the DPF is showing about 12-1/2% clogged!
I sent a pic of my DPF from my dash display with the odometer showing to the service manager. I then called her and she asked me to set up another appointment to have it looked at again.

Neither of those recalls will have any effect on regen frequency.

Before I started to use Archoil I was getting regens in the 275-325 mile range, after I started using Archoil I could get 675-700 miles between 24 hr regens, I just got back from a 14 day 4544 mile trip, I was able to go what I thought was a fantastic 1467.7 miles between my 24 hr regen, this surprised me as I was forced to use a few tanks of B10-B20.....

Yesterday afternoon when I started the truck it showed the same about 12-1/2% on the DPF gauge. After driving about 5 miles and one stop I drove on the freeway again and looked at the gauge and it showed 0%. This was after about 5 minutes of driving at 72mph.
WTH is this thing doing?

What I question is when they look for codes do they automatically reflash any software to the latest or a CA updated version

Combination of passive regen, and mostly the truck reading the soot level. I personally think there are some calibration issues with back pressure and soot loading. What you saw on a cold exhaust is similar to what I’ve seen, which is a quickly dropping DPF gauge when cold and empty. It will likely climb fast if you do stop and go when warm again.

That’s a “normal” thing and wasn’t impacted by the recalls you had done.

 

[oledirteh]

im getting about 1150 miles between regens right now. this cycle ive had about 25% down to 12% on the gauge and it will go up then down. ill prob hit 24 hours this week as its about due.

 

[Resilient]

My DPF gauge has never showed a lesser percentage of soot after showing a reading. The gauge climbs steadily, and it does not matter if I am driving 70mph unloaded, driving 60mph towing my boat up a long grade or driving 25-35mph in town. Once that gauge starts moving it has only climbed higher until regen. While freeway driving during a regen the gauge would start climbing after a short while and then go into regen again in less than 1 tank of fuel.
On a different note. I drove to the airport to pick up a couple friends last night and received a little surprise. My friend said “You are not going to like to hear this. Your passenger side headlight is out”. I guess 3yrs is how long headlights last before giving up. I can accept that. I will pick up a new pair of low beam bulbs today and look up to see if there is anything tricky about replacing them.

Is the truck running poorly?

If not just drive it and leave the cluster on the boost pressure screen.

O n my resent vacation my DPD showed zero then jumped to the auto regen in progress message an seeing it, it let me know it was a 24 hr regen not a soot loaded regen...

Truck is using extra fuel with frequent regens. Fuel here in CA is close to $5 a gallon. When the truck goes into a regen, I need to drive an extra 20 miles or so for no other reason on the freeway because you shouldn’t stop the drive cycle during regen process. Waste of fuel, and time.

Based on what I’ve seen only soot based regens shouldn’t be interrupted. If the regen is 24 hour based then there isn’t a need to run until complete. 24 hour based regens also haven’t taken 20 miles to complete in my experience, on average they are shorter than that.

I have had 5 or 6 Ram HD trucks since 2017. Not once did I ever worry about regens....or interrupting regens, passive or otherwise. There seems to be a lot of speculation on this forum as to the conditions and what triggers a regen. No where in the 0wners manual does it say to never interrupt a drive cycle during regen, it does say the emissions mode can last for 20 minutes of drive time but does not say that must be continuous. I think even the grocery getters can do 20 min straight of drive time daily.

I daily drive about 30 miles a day during the week and then on weekends as well. I tow our 5th wheel maybe 4-5 timers a year. These trucks will let you know if something is truly wrong - the engineers did not slack on warning messages and chimes on these trucks. They also engineered them to be driven as daily/weekend warriors or as the the Hotshot guy hauling everyday.

You can nerd out on regens and tracking the cycles but the Engineers did that already. Just drive the truck...sometimes I think people over think this stuff and create issues that are not there.

"If the engine is allowed to idle or the truck is driven
on low engine speed drive cycles for more than two
hours, the system will automatically enter an emissions
operating mode that will increase the engine idle speed
to 900 RPM. While in this mode, which is designed to
help maintain the Diesel Particulate Filter, the engine
idle speed will return to normal when the brake pedal
is applied. A small change in engine tone or a slight
change in engine performance while accelerating may
also be noticeable at speeds below 20 mph (32 km/h).
This operating mode may last for up to an hour of idle
time, or around 20 minutes of driving time."

Exhaust Filter Nearing Full Safely Drive at Highway
Speeds to Clear — When the Diesel Particulate
Filter (DPF) is 40% full of particulate matter, the
vehicle will look for opportunities to automatically
enter regeneration mode, without alerting the
driver or requiring any action. However, under
conditions of exclusive short duration and low speed
driving cycles, your Cummins® diesel engine and
exhaust after-treatment system may never reach
the conditions required to remove the trapped
Particulate Matter (PM). If this occurs, and the
DPF reaches 70% full, the message “Exhaust Filter
Nearing Full Safely Drive at Highway Speeds to
Clear” will display at key-on and when the vehicle is
in PARK. If your vehicle has an instrument cluster
with analog gauges it will display the words "at
Consistent Speed" instead of "at Highway Speeds".
Either message will be accompanied by a single
chime.

Although it is not necessary to immediately drive
at highway speeds to address this, or to continue
driving once regeneration has started, it should
not be neglected for long. The fuller the DPF is,
the longer the regeneration process will take to
complete. For example, if the DPF reaches 90%
full, complete regeneration will typically require 45
minutes of driving to restore the system to normal
operating condition.

● Exhaust Regeneration In Process Continue Driving
— If the DPF reaches 70% full, this message will
display with a chime when the regeneration mode
is automatically engaged while the vehicle is being
driven at a suitable speed. This will repeat every
three minutes while the DPF is self-cleaning, until
the particulate level is reduced to zero. If time or
circumstances do not allow the vehicle to continue
to be driven, the system will resume regeneration at
its next opportunity and will redisplay this message.

● Exhaust System — Regeneration Completed — This
message indicates that the DPF self-cleaning is
completed. If this message is displayed, you will hear
one chime to assist in alerting you of this condition.

Exhaust Filter Full — Power Reduced See Dealer —
This message displays if the DPF reaches 100%
full. It will be accompanied by the Malfunction
Indicator Light (MIL) and a chime. Engine power
will be reduced. At this point, regeneration is no
longer possible and the vehicle should be taken to
an authorized dealer as soon as possible to have
the DPF manually cleaned. In extreme cases, a
completely full DPF can damage the exhaust system,
requiring part replacements. For these reasons,
never let the DPF reach 100% full.
NOTE:
The DPF gauge on the Premium Instrument Cluster
remains available during DPF regeneration. Analog
Instrument Clusters will display "Automatic Exhaust
Regeneration In Progress" in place of a value.
NOTE:
Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by 0
miles remaining will prevent the diesel exhaust filter
from performing its cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and
reduced engine power. Only an authorized dealer will
be able to correct this condition.

I dont get the whole worrisome of the DPF. I also have owned many Rams and have stoped / parked mid regen with out issue. I feel this has surpased the CP3 worries and post. I say just drive the truck and enjoy it.

I don't get it either...when I see these posts I picture a guy popping Antacids like candy and updating his Excel spread sheet on the center console flipping out.

 

[AH64ID]

It’s pretty simple actually, the 19+ trucks (especially 22’s) have proven to be far pickier about driving style, filters, etc when it comes to regens. DPF’s are expensive and paying attention to how a truck regens will probing its life.

I’m very much a fan of drive and forget but unlike my 2018 that was not possible on my 2022. If everything worked as intended then we wouldn’t even have this thread, but it’s not working as intended.

Sstoner911: my opinion on points of this thread is prevention and understanding the system, so as to not or never achieve a 100% full dpf and need a manual cleaning keeping the system healthy as it were. In part I like the ideas of what I've read in your post, but have never heard any "chime" for anything and only know its in regen if the filter screen is displayed.
