Automatic Regen too often

I'm not sure what size of tube is on the my UOA suction pump I bought from Amsoil, but I was able to easily get the tube down dip stick tube far enough to get an oil sample on my truck its a 2022

Well, I stopped by and ended up snagging like 42 oz. Mostly because once I pulled the plug it came out quickly. However, given how far above the full line it was I doubt it made any difference. Now off to fleetguard. Whenever I get the truck back, this will just be done with each oil change, and any other time it may seem necessary. Thank you for the Amsoil info. I'll try to order their siphon pump.

The dealer has had the truck 50 days as of today. However, in talking to the second tech that it has been upgraded to (their most experienced level 3 tech I guess) after the guy assigned to it quit - he has some plans that just had not gotten to. He will be testing the egr, testing both the injectors and pump, and checking the ccv filter. This is all planned to take place next week, and probably the following week given the 4th holiday. I've been nice and will continue to be so, but was direct in that it better be ready for our vacation in August because it was already rescheduled from the original June date. Additionally I know the truck sat 11 days untouched after the last tech quit because I found out via ram cares the star case was closed due to lack of response.

Anyways, I just want it fixed and fixed right. I was tired of fighting them on an OA so now I'll do it for them.
 
Curious how much soot, if any, y'all are getting in y'alls tailpipes. Happened to be looking under the truck tonight since I had a few minutes and was thinking about tackling my rear control arm swap if my back starts feeling better with the long weekend coming up. I noticed that before my inter-cooled tip the pipe was black and if I reach up and run my fingers loosely over it I get black soot. Not grey, not ash, but black soot.

It's not a thicker coating like you find in the intake from the EGR, more like a light dusting - but its there. The other truck's not around at the moment since my folks are on a trip so I can't go easily compare.

Thinking I might need to force myself to find the time to get the PM sensor recall done and force them to take a look at my DPF to see if it's cracked so it can get warrantied right then and there if it is.

Sounds like a failed DPF. There shouldn't be any soot in the tailpipe.

Figured as much... I always remembered intact trucks being pretty damn spotless so when I noticed it dark I was like FML. I monitor temps and DPF loading pretty religiously as emissions equipment failure/issues is one of those things I'm borderline paranoid about - IMO the least reliable aspect of modern diesels hence why it's always on the back of my mind.

I guess time to call the dealer on Monday. Luckily she hasn't been driving any differently so at-least if I NEED it in the short term she's running - Just gonna keep a real close eye until I can get into the dealer.

I doubt they will do much if there is no dtc. You have extra warranty on the dpf after they do the PM sensor recall so I wouldn't loose sleep. My tailpipe is not spotless either. I had the PM sensor recall completed about 2k miles ago and no dtc yet for dpf efficiency.

Sorry for the stupid question, what is the PM sensor?

PM = Particulate Matter sensor
It is a sensor that is installed at the very back of the SCR chamber, at the end of all emissions aftertreatment. Its job is to monitor the output exhaust flow and look for soot particles. It can capture and “count” soot particles in the exhaust flow. If the amount counted is larger than a preprogrammed value, it’ll trigger a DTC indicating that there’s excessive soot present in the output exhaust. This would indicate that the DPF has failed (either the media is cracked or the canister is leaking) and is allowing soot to escape into the environment. The DPF’s are about 99%+ efficient at trapping soot. There should basically be no soot present at the tailpipe. Even if the DPF is full, it shouldn’t be allowing soot to bypass.

Thanx for the explication, I seem to struggle with different abbreviations and did not want to make a a$$ of myself.
DPF concerns are caused by many many factors and the most common are air leaks, thats intake and exhaust leaks. Overfilled sumps and wrong spec oil. Engine coolant temperatures and short trips.
This is a interesting tread and when regen takes place the proses needs more fuel to do the burn and some of that extra fuel ends up in your sump. Its really concerning that the dealers dont renew engine oil during these concerns they are trying to resolve, we always renew the engine oil after any DPF concern repair.

As i understand it, that lack of oil change comes down to what Stellantis / RAM has defined as part of the repair process / procedures. If it isn’t explicitly called for, the dealership won’t do it because RAM will not reimburse. There are many repair procedures that need significant revision from what I’m told.

My tailpipe is a bit darker/sootier than yours, but yea most likely knowing the dealers around here my concerns will go nowhere unless it pops the 2002. I'll still get the recalls done (I've been meaning too, but between work, medical issues, and wrapping up our move I haven't had the time), but I might end up talking to my friends in the great white north about a proper repair if it pisses me off enough and the dealer won't look at it.... My time is more valuable than the cost of fixing it permanently.
 
The saga continues - Needed to run into town to get some stuff for my daughters bday. I figured I'd go ahead and re-calibrate my pedal monster since it had no problem commanding 100% throttle, but down low it was a little twitchy. Went straight from key on, pedal relearn complete, to foot on brake turning over. After she fired up the EGR PID's errored out. At 1st I thought it was just an idash bug, but the truck ran like it was EGR off and I did double check it wasn't in regen. It RAN GREAT - I mean seriously she hasn't run that good ever when its this hot. The NOX PID was reading north of 1000 ppm so I also assumed that EGR wasn't happening. Got back, shutdown, let it go to sleep, and refired - EGR was back, but then the NOX pid was reading 0 PPM which it never does even at idle. Gonna make that call to the dealer tomorrow to get the PM recall done, but I just think there's something deeper going on with the emissions systems on these trucks. I'm the original owner, its only ever been worked on by the dealer, myself, or the navy vet I used to use before he moved. Only party to ever flash the truck has been the dealer after the ECM recall.

Didn't grab pics of the other PIDs while I played with it, but here she is going down a farm road showing no EGR pids. ECT was bouncing between 185 and 190 and its 100 F out here ATM also making me think EGR was indeed closed.

There should be a PID to show EGR %

If you notice both the EGR CMD and EGR ACT pids blanked out. Once I let the truck sleep and restarted her they were back, but then the NOX pid was just reading 0. It's never done anything like that before.

edit* Also didn't throw any codes either CEL trigger or hidden codes waiting to trigger an CEL.

Gotcha, yeah bizarre. I’ve never seen that before.

I wonder if my NOX sensor is on its way out and causing the tune to internally fault or something ??? Maybe whatever the hell cummins did around the 2024 fines was either half baked or has some race conditions in the logic leading to odd behavior. At this point I think its anyone's guess as to whats going on, but it seems like either here, IRL, other forums, reddit, etc I see/hear/follow a number of guys just having all manner of emissions gremlins with no rhyme or reason.

Dang it you guys are making me worry my new truck is waiting for me to pick her up.

Nah, you’ll love it. However get a CTS3 or Banks Gauge from day zero so you can learn the habits of your truck (especially when it is time to regen for whatever reason).

Keep records of everything, log regens if possible and if you drive it short distances a lot, take it out for a good long drive or tow something.

There is so much good info here it makes life so much easier.

Our other 2500 has been emissions issues free and see a lot more idling and city miles than my truck. It really does seem to be luck of the draw.

What makes it even worse is the amount of crap on these engines that if one piece gets out of kilter, it screws the whole thing up. There are so many different subsystems that have to work together as a whole that makes it very difficult to pinpoint exactly what the problem is. Throw in a tech that has never worked on one of these systems and it’s a miracle if they ever get it figured out if at all.
I’m fortunate my truck is doing great and not exhibiting any bad behavior yet. If it does, we’re going to big D and don’t mean Dallas.

Yea its too bad RAM didn't see fit for all the extra garbage to go the way of my connected services from the factory ... Non existent.
