Dpf fed up

WEEZY1 · Jul 13, 2022

I have a 2020 tradesman that has 18000 miles on it in two years, my commute is 10 miles each way. I’ve tried to do what’s right but yesterday my ram decided to regen about the time I pulled into work to park. I ran inside dialed in to start my day, went back out to drive it and it now comes up and says dpf full in limp mode see dealer. Tried to look up how to manual regen and there is NOTHING in my manual about how to do it. Took it to dealership where I service and they tried and said it has to be replaced??? At 18000 miles? Getting real tired of this smog crap that does nothing but restrict my rams capabilities. Any suggestions? Plus they can’t get the part for like 2 to 3 weeks? Must be a huge issue. Never had this issue with my 17, 3500. Don’t see a need for def and dpf!

You don't see a need for it but unfortunately the EPA feels differently....

Your biggest issue is the 10 mile commute to work, that is hell on a modern diesel emission system. Your truck never gets warmed up and never has enough time to complete a regen.
It's not a huge issue at all but parts of every kind are hard to get right now so that's why the wait. The system you have on the 20 is really no different then the one on your 17 so it's just bad luck.

I know what you are after but unfortunately it is becoming more and more difficult to delete at this point. Tuners are out there but they are becoming few and far between with the EPA cracking down on them and closing them down. Lots of fly by night people selling tunes as well so it can be a crap shoot.

You can get an Edge Monitor. It monitors all the main diesel parameters (regen, EGT's, etc.) and allows the user to initiate a regen cycle.

After you get this fixed, you’ll have make sure you get out on the hwy every so often to clean that filter. Others that own one may be able to advise how often.

One thing I do is stay away from Bio Diesel, my self I try to get mine out on hwy at least once every 7-10 days of town driving of under 10 miles, so far have had one regen in the last 72 hours on engine with 62 of that driving and the regen happened the day after dealer had truck sit at idle for over 30 minutes for software update... Also Alf OBD can be used to do manual regen, clear codes and a whole lot more...

I don’t recall my 17 having dpf, had def but never had any regen on it and never had a problem with it other than normal recall stuff, and I drove it exactly the same way I am this newer one. I agree the problem with not putting a lot of miles on it, mess with the dpf but seems like a design flaw to me that I’ve noticed other people using the same way are having. If you only need a diesel if your putting a ton of miles on it then a lot of the farmers/ ranchers in my area are in trouble. Seems crappy I have to put 20 extra miles on my truck each time it decides to regen to keep it from stopping up especially with fuel prices the way they are now

Unfortunately your issues are probably due to your driving habits .Short trips are brutal on diesels . They need to run long and be worked hard .

I had a 2015 ED, Gen II. I sold it after 10K on Odometer. Now, nothing wrong with the truck, but I was not working the diesel. U have to work a Diesel every once in a while. I had a Blue Driver Monitor and knew when regens occurred. But since mostly daily driving to town and back, once a week I would do a 60 mile loop on a state highway at 60-75 MPH to make the motor did a full regen and keep it cleaned out. There are a lot of good people that were on the ED Forum Site and provided a lot of info. I sold because did not want to throw the dice on a EGR/Main bearing failure. The Gen III ED's supposed to have dealt with that issue, but alas, FIAT/RAM/STELLANTIS pick a name discontinuing the ED for RAM in Jan 2023 anyway.

ADDED: Not trying to compare a ED to a CTD, but the DEF/DPF principals are the same and needed usage ref regen the same.

Alot of issues with the eco diesel is software is Fiat based where as the Ctd is not . I was having an issue with my Ctd but no codes. Finally tripped a code ,10 fix but was worried about the countdown to limp mode. I was told by the tech , known him for years and what he told me about Eco's was scary . When countdown hits 0 and goes into limp mode , can't reset computer you replace it where as the Ctd it's a simple reset . This may have changed.
I was not using my 3500 ctd as it should be and that's why I went to hemi , much better suited to my driving habits.

Before I bought a new 2022 2500 CTD, I read many forums about the current HEMI BS, what I read sealed the deal for me to buy another CTD an take the chance of dealing with DEF & DPF...

Set your cruise when parked turn on your engine brake and set your idle up the 1100 rpms. That will increase your temperature in the system to do a manual regen.

It won't get anywhere near hot enough to regen doing that, you are just wasting fuel and making it worse. I've monitored the DPF temps so I'm not just guessing on this.

Funny when a dealership does a force regen on a truck that is the exact combination that they use. It was my local ram shop that told me this and watched the computer doing it to my truck. But when it is running down the road and it does a regen the rPMs are only around 1500 as a norm in my truck.

AlphaOBD->Engine manual regen:
The one time I did it it ran for 35min. Went from 97% (Torque Pro "DEF Status") to 15%.

A forced regen is a function where the truck dumps extra fuel on the exhaust stroke to heat up the DPF, It's nothing like just idling your truck. It has to be initiated by a dealer tool or something like AlfaOBD, the truck doesn't do it by just high idle

Bad info. The Edge will not initiate a regen on a 6.7

I have a 2021 3500 HO cummins. 15K on the clock in less than 24mo of ownership. Inthe first few months of ownership, I took some long trips...9k of the miles has been in the last 16mo, around town, no freeway, short trips. The truck really doesn't need distance to regen, it needs heat. If you let it idle and warm up to temp before leaving the driveway, the 10mi drive to work will be sufficient to regen the truck. Same thing on the way home. It needs heat, and if 6mi of your drive is spent getting it to temp, you'll always have an issue.

Are you sure you are regening in that scenario?
My 2020 HO takes 20-25 miles to complete a regen.

You've never seen how long it takes to go ten miles here in Pinellas county, FL :favorites37:

PS: In the last 4 months, I've never taken a trip longer than 10 miles. My DPF regens when showing 25% and goes to zero all the time. That's all I know. :cheers:

Gotcha
My 20 mile regens are @ 70-80 mph and my 25 mile regens are @ 60-70 mph all while tripping on wide open freeways.
My 2016 Ecodiesel takes 9-15 miles @ 60-65 MPH on local freeways. Our SoCal freeways stack up like yours, 45 minutes to go 10 miles, being retired I don't drive at those times.

My DPF gauge has never moved. I monitor with an Edge CTS3. MY 2020 HO regens start at 100% and finish at 9%.
The Ecodiesel starts at 65-70% and ends at 9%.

Dpf fed up
