Ok I have an update:

The dealership (AutoNation Colorado Springs Dodge) finished replacing the fuel pump (Recall Y78). The instrument panel says the DPF is at 0%. I spent some time Yesterday going through the work history (receipts). It looks like I have taken the truck in for manual regeneration about every 3,500 miles since I bought it. And the dealership has replaced the DPF every-other time (first time at 7,738 miles, and this time at 14,219 miles).

The first time they replaced the DPF the tech. noted that the Turbo was under boost. It doesn't say that they did anything to correct the it? It does say they replaced the DPF and re-flashed the computer. According to my receipts the dealership has re-programmed the computer 3 times (Recall VB6 @ 1,742 miles, Reprogramed at 7,738 miles when they replaced the DPF the first time, and Recall Z20 at 14,172 miles). Just to be safe I had the dealership replace the fuel filters at my cost each time they replaced the DPF.

I would really like to solve this problem once-and-for-all before we retire next year and start traveling with our 5th-wheel trailer.

Jesus does Colorado have lemon laws? That many major issue with the truck I would be looking into getting Ram to buy it back, your time is more valuable you should not have to deal with this.

What year is the truck ? If its not a 2022 there are other options

I know it seems weird I went through a probably 6 month period chasing down odd drivability and soot loading issues. The truck ran well but seemed to regenerate a lot more and got worse mileage then my fathers nearly identical truck. I thought screw it I’m delete it buying into the delete the world crowd. I delete the truck with a highly rated tuner, it runs great but is really smokey and the transmission tuning is weird… frustrated after the delete company won’t really help me anymore and say I’m driving weird. Pissed I undelete the truck running it stock for a while but it irritated me that I had installed a built valve body but wasn’t using the advantages anymore. I caught a calibrated power tuning sale and decided to go for it. Now all of this occurred in while I was living in a very flat part of the county. I would visit friends in the Rockies and began to notice weird drivability issue 100 mile regens terrible mpg and what I can only describe as surging in the mountains. I sent calibrated probably a dozen data logs finding nothing wrong with their tune or stock files they suggested I buy a boost tester and check my truck. I ended up finding two massive boost leaks, and several exhaust leaks at the egr cooler. I fixed all of leaks, my truck has never run better to the point I’d say with a great degree of certainly the boost leak at the air horn was a factory doink….

Kind of a long story to say check it it’s a real issue and caused me to burn thousands of dollars in delete parts collecting dust, replacement sensors that are probably good, and to almost trade in my truck for a 7.3 gas superduty and swear off diesel forever.

You had massive boost leaks and the boost gauge read full boost?
I didn’t think those were fake gauges….

@Yakkety Yak , quit being a sucker. “Dlr replace fuel filters each time just to be safe, on my dime.”

Good lord….must be made of money…
I like to keep mine!

Not sure I understand your point.

Well it is my money to spend. Have a good day.

It's a late 2019 that I bought the beginning of 2020.

The Dealership just replaced the DPF filter again!!! This is the third filter (2nd replacement) in my truck and it only has 17k miles on it. I am getting real tired of taking it into the dealership to have it manually regen'ed. It does the auto regen until it reaches near 100% and then it won't regen automatically any more, and I have to take it into the dealership. They manually regen it until they just can't do it any more and they replace the DPF filter.

Anyone else having this issue?

FYI - the only mod I have on the engine is an S&B Cold Air intake.

Is there any outcome in your case or they still replacing DPF filters every other week?

 

[Yakkety Yak]

No. 😖
Last month Dodge replaced the DPF again (this is the 3rd DPF). Dodge also replaced the fuel pump at the same time. And I put the factory air intake back on. We are planning a trip with the 5th wheel next month. That should be a good test of both.

Haven't heard anything more from RamCares.

I suspect it is an ERG related issue. I hate the idea of recirculating dirty exhaust back into the engine.

 

[H3LZSN1P3R]

The issue may have been a CP4 related problem time will tell

yes... the DPF getting full is just a symptom, not the problem. Continuing the just replace DPF after DPF is foolish.

Yea most of the time its EGR valve is sticking open a little and letting in way too much soot. I would fully pull the EGR system, cooler and all, then preform the service on it to clean it all out and inspect. I think they stopped requiring newer trucks to do the service. On older trucks it was the 67,500 miles service. But it would still apply.


at minimum pull off the EGR valve and inspect. A bath in purple power wont hurt. its super easy and the most common suspect.


I do admit I dont know much about the changes in the newer trucks, so someone correct me if I'm flat out wrong here.

You cant pull the EGR valve apart to clean them on these trucks either they work or they dont also even at 250k most people have almost no buildup in the EGR system due to how little EGR they use. I would be willing to wager it was a fueling issue due to the CP4 that little ******* caused so many issues

I hope you are right. I'll let everyone know how it goes after our trip to down to Carlsbad Cavern next month.

 

[Grit dog]

Not sure I understand your point.

Sorry, my point was truck has a boost gauge. So if you had massive boost leaks, one would think it would be evident just by looking at the boost gauge.
Similar to exhaust leaks which even a very small leak upstream of the turbo can be heard pretty clearly when the exhaust brake is applied.

 

[Grit dog]

Correct and apologies, I didn’t say that very politely.
What I meant was there is zero connection between fuel filters and any dpf issues or suspected dpf issues.

The 2014+ trucks use a lot less EGR than the previous years (07-13 pre DEF)

I believe you are correct. The filters were showing around 50%. And I had a larger fuel tank (52 gal) put on a couple of months earlier so I figured it might be a good idea to replace the filters, in case something from the tank was picked up.

Yes i did say they use very little EGR… also DEF started in 13 not 14

I guess I said “never” too early to my issue with DPFs. I posted it in another thread and just leave it here, if someone could help. Thanks!

“I have the same issue on one of my 2019s. It never does automatic regen while idling, no matter what temp is outside. Dpf gauge fills up to 50% in about 40 miles of highway driving. Then automatic regen kicks in, the truck shows 7-7.5 mpg under 15k load at 65mph highway driving. Normally I get 11-13 on my other trucks under the same load. I’ve rarely seen automatic regen on my trucks bc we do highway driving 90% of the time. I’ve never seen DPF gauge to fill more than 1/8. So this truck turns on automatic regen on a highway and stays on for hours and DPF filter never fully empties, stays at about 50%, permanently in regen wasting diesel. Regen turns off only when I shift to park and then goes back on when I start driving. Stationary desoot works perfectly. I tested it several times and the truck was able to desoot every single time to 0%. During forced regen all live data shows normal, egr closed, actuator at 10-11%, ~1050f on DPF temp sensor. I cleaned egr valve, egr cooler exhaust pressure sensors and tubes, replaced DPF pressure sensor, checked for exhaust leaks and couldn’t find any. Still the same. Stationary desoot works great, automatic desoot can’t clean the filter. Truck can idle for an hour when it’s cold outside with DPF say at 50% full and never increase Rpms to burn the soot and can’t efficiently fully empty the DPF while driving on a highway either. I appreciate any help and where else to dig, what data to check!

I scheduled for cp4 recall plus software update to seeif it helps”.

I am beginning to think this is a serious design issue. I have gotten several good suggestions from other members, but none of them have worked. At this point I am ready to delete my truck after the warranty expires. I have some friends that deleated their farm truck and they love it. More power, less pollution and better gas mileage. Win, Win. Win.
