Frequent Regen 2020 6.7

[Electrified]

Mine does the same thing. I have more miles but it’s been doing it since probably 40000 miles. And just to clear up your warranty is only 50000 miles for emissions yea I know. I thought it was drivetrain also. They have done all mapp sensor change air filter Supposed to be a computer update in May. The service manager is really working on it and has found out this is a major issue with them. I talked to them today and said he is still waiting for update.

Thanks for the insight. This has been doing this for the last 10k miles. Hopefully they'll cut me a brake on the 2k miles. But I wont hold my breath.

They should there helping me out .I paid for a mapp sensor, but haven't charged me since, also a claim can be started through Ram cares for financial issues if needed.

Looks like I’m heading back down the regeneration slide again. The truck has been flawless since November of last year. 7 months straight with only a 24 hour regeneration and no soot load registering on the dash. Fast forward to this week, I’m 424 miles since last regeneration and over 25% on the gauge already. Same drive cycles, same speeds, same routes, same fuel, same filters, same driver, same fuel station…….literally every factor the same except that the weather has been getting warmer.

The truck didn’t miss a beat over the past 7 months and now it’s climbing like this for the second straight week in a row. Almost like it’s starting to repeat the same regeneration cycle stuff it did back in July of last year.


I consider myself very well versed in these systems and the operation of the truck generally, but this regeneration system has me utterly baffled. I fully believe there’s a malfunction somewhere, but finding it is going to be difficult

I had something strange happen last week, changed oil, air filter and fuel filter at 10,500 miles. It did a soot based auto regen at 525 miles and 13 hrs (right around my average) since the last regen just before the service. A few days later, at about 15% on the DPF gauge and 175 miles and 4 hrs it did another auto regen, which I thought was strange. Just had another soot based regen, 45% on the DPF gauge, yesterday at a little bit of a longer interval 216 miles and 5 hrs. Hopefully it keeps the intervals going longer and longer, maybe it just needs to relearn after the new air filter, idk. I have not changed my driving habits and before anyone asks, my oil level is at the top of the hash marks and I bought all my filters at Geno’s, so they are legit. If it continues this trend I’ll take it to the dealer and have them look at it since I have the steering wheel module recall to complete anyways.

These regen frequencies are hard to nail down. I thought I had it figured out as well.

26 miles later…Nearing 45% and the regen trigger point. A whopping 450 miles since last regen finished. The last seven regeneration cycles were all 24 hour timer-based and the soot load stayed pretty much 0%. 7 months worth of timer based regeneration cycles with an average distance of 938 miles between them. Absolutely zero change in any factor except the date. Now this thing, out of the blue, can’t make 500 miles or 12 hours before it’s loaded up to the point it’s ready to regen. It makes absolutely no sense.

Thats how mine behaves. Never had 0% for 24 hours tho. It never clears out on the highway (85-90) either. My favorite is automatic 1/8 soot load when i refuel. Its usually every other tank i get an auto regen. I feel I'm somewhere in the middle of the regen debacle.

Could be fuel, try a different station.

Could be, but that’s the same thing he did to rectify his frequent regens prior. I’m wholly convinced it’s in the programming. From what I’ve seen and experienced with my truck, if you’re not towing at least 50% of the time, you’re going to see soot loading variations daily driving the truck.

What I’ve discovered with my truck, I run 75 about 25 miles on the interstate to work in the morning and the DPF gauge will jump up some, it’s not quite far enough to get a real good passive regen. Kind of just a net zero, as soon as I jump off the interstate though, I use the skinny pedal and do a real good run up to 70mph and after driving for a bit after that, the DPF gauge will jump back down some.

I thought that initially but I’m using the same fuel station I used when the regen frequency issue corrected itself the last time. The only change I could see would be the switch between winter fuel and summer fuel. I spoke with the fuel specialist for this particular chain of stations and he assured me they only sell B2 diesel at their locations. If you look at my regen data sheet. The frequency between regen cycles picks up when we go into the spring / summer months and then improves as the weather here gets colder. The truck runs the same daily drive cycles for the most part. This will be the second time. It has to be environmental or the change to summer fuel (or a combination of both)

Well…

502 miles and 14 hours since last regen cycle.
My prediction: This will be the beginning of the downward slide again.

Do you use a branded fuel station or unbranded? Unbranded (Loves, Flying J, similar) can change contracts for who they get their fuel from. Branded (BP, SHELL, Chevron, Phillips66/75/Conoco, Marathon, TYPICALLY! I’ve seen them use other companies refineries/tank space) can still get fungible product if they source from an interstate pipeline.

I use a local BP / Amoco station that is owned by a large local energy company (Coen Oil). It has seemed to be very reliable source for good clean fuel and after speaking to their fuel specialist, I have their assurance that the diesel they sell at all locations is B2 only.

80 is net gain for me. 2 hours at 75 still builds suit load, albeit 1/4. I'm at the point where the 18-20 mpg at 70-75 and active regen every other tank at 45% is better than 16-18 and overly speeding to try to passively regen. My truck just doesn't wanna.

The next question to them is, during the winter months are they mixing in #1 diesel to winterize the B-2 ( I assume it gets below 32 degrees during the winter months in PA) or are they using strictly anti gel additives to winterize there fuel...

I would think they’re sticking to additives only. And yes it absolutely gets below 32°F here in Pa during the winter. Seems like we usually linger in the teens and low 20’s for a decent portion of the winter.

31 miles since last active regeneration cycle finished:


Definitely back on the downward slide.

Did you recently do a service? Just curious.

No I’m about half way through the current service interval. Fuel filter and oil filter life showing 45% and 46% respectively. All OEM filters.
