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.

Very little city driving. I tend to do some 60-mile round trips into the mountains, and some hauling a 5th wheel on vacations. That's about it.

Would not disagree, but I can't figure it out. And the dealership has no incentive to do anything more then what their failure mode tells them to do. They plug it in and it tells them the DPF is full so they do a manual regen, and plug it in again. If it still shows the DPF full they replace the ceramic filter and call it a day. Dodge doesn't pay them to do anything more. I have thought about putting the factory air intake back on to see if that fixes the issue, but I had it on the first time they replaced the filter. I have to say it took longer the first time though?

Hi Callie,
My RAM is still at the dealership having the CP4 fuel pump replaced with the CP3. They told me it would take a couple of weeks. So any suggestions would be welcome.
Thanks, Leonard (Yakkety Yak)

Did the dealership pull any codes from the truck? I had pressure sensors failed in couple of trucks, and that’s about it. Never had another problem with DPF even when “daily-driving” for several months without putting my truck under the load to burn soot. Go to a good diesel mechanic if your dealer so messed up
They said the only code was for the DPF.

When I was looking for my 2500 came across a newer 2500 that was priced lower than most 2500s. Low miles and just over a year old. Turns out it was a Lemon Law return. Ram was never able to repair a leaky door….
I bought mine new from Rocky Mountain Dodge at the beginning of 2020.

Sorry to tag onto this but it looks like a conversation associated to my problem?
So, regarding the thread and the DPF and dealers, I just had the actuator replaced by the dealer (extended factory warranty). After they installed it they called and said the DPF is full and will not regen they want 5K to replace the filter. I picked it up today and drove until the regen complete notice appeared. Can the malfunctioning actuator and limp mode cause the filter to fill up?
I started a ticket with Ram Cares. I'll let you know where that goes. The truck is currently in the shop having the CP4 fuel pump replaced under recall.

@Yakkety Yak, how many miles were you driving in-between regens? Based on your reported driving habits, I would estimate that you should be able to drive 800 - 1,000 miles in-between regens.
Just before I took it in it was trying to re-gen every time I drove it.

Thank you for the information. I am a little lost on how an exhaust leak would cause the DPF to fill up with soot. Or are you saying the DPF is ok. But an exhaust leak is tricking the sensors into thinking the DPF is full?

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.
Hum. I just watched a video on the boost leak test you mentioned. After I get the Truck back I am definately putting the factory air intake back on and checking for leaks. Thanks

Just got my truck back today. The DPF reads 0% and the new fuel pump sounds good. Will take it for a test drive tomorrow and see how it does.

I went back through my service records and the original DPF was replaced at 7,500 miles. This one was put in at 14,700 miles. By my calculations that's a new DPF every 7,500 miles. On the paper work for the first DPF replacement it showed that the tech. pulled a code for Turbo charger under boost. I don't know if that was a symptom of the DPF being full, or a cause?

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.

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.

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.
