regen frequency

[Andrew Jahn]

I've had that done....

I did try going the dealer route... I was told that their diagnostics wouldn't turn up anything if there were not any codes.

I have a monitor. I can see when the Soot level reaches 100% and when the computer triggers a regen. I do not get the EVIC message everyday. Its the background regen.

2014 with 79,000 miles.

At what soot % does it complete/finish regen?

have any of you tried Diesel Deep Clean from Lucas Products? https://lucasoil.com/products/problem-solvers-utility/diesel-deep-clean

I tried one can some time back, can't say if it works or not as its one of those things that are tough to quantify using seat of the pants measurements.

as an aside, I can't speak for what goes on with these monitors civilian end users have on their personal trucks but I can say regarding stationary regens on Cummins ISB equipped vehicles while observing parameters on Cummins Insite while doing a stationary regen, will commonly see a soot load of 3+ ounces at the beginning of regeneration and by completion of regen the soot load is zero ounces. stationary regen can take 45 minutes.

Just want to point out that driving 20 miles at a pop may not be long enough for the DPF to clean itself completely in light load driving

I agree. It will take 5-10 miles just to get up to operating temps..... depending on ambient temps.

I used to run a cheap obd II monitor that displayed real time on my phone. I did it just to get a feel for what was happening with the sensors and especially with the dpf. (Temps and pressures)

I could see that the active regen always happened after it was completely warmed up and wouldn't ever start right after getting up to operating temps, but would wait about 5 mins (approx). Some will say to drive at 60-70 mph for a good hour once every 2 weeks.
I don't know if the suggestion actually helps.

Regen showed complete once it reached 25%

I have been using the Lucas oil deep clean. Agree that I can’t say it does anything

My 2014 6.7 Ram has been regening every day for the past multiple months. No Codes - so the dealer says nothing is wrong. Its averaging 30 to 40 miles between regens.
I drive 20 miles to work and 20 miles home - all highway averaging 55 to 60 MPH.
When I first got the truck it wasn't like this. The MPG's have dropped from low 20's to mid 17's. Mostly due to the constant DPF regen.

I'm at a loss and with the dealer not showing anything I don't know what to do.

Has the dealership you've been to performed a stationary regen?

 

[Andrew Jahn]

Has the dealership you've been to performed a stationary regen?

No. They haven’t.

 

[Andrew Jahn]

No. They haven’t.

I have inquiries into a couple of diesel shops to get their opinions.
I’ll let you know if they have any suggestions.

 

[skorski]

I AGREE WITH SNOW KING 75k ON THE 14 AND NEVER SMELLED A REGEN . if ANYONE CAN SMELL IT THEN YOU MUST HAVE A LEAK IN THE CAB AND HOW CAN A SMELL COME IN AT 50 MPH ???

 

[6V92TA]

if you happen to come to stop while in the process of regen and the breeze is blowing the right way you may smell it, especially if the HVAC isn't set on recirculate or you have the truck windows open.

 

[Newsa]

No. They haven’t.

They won't do that under emissions warranty unless you get a "DPF ash full warning ... See dealer" Can't remember the exact wording of the message. But it is something like that.
That is probably why the dealer is saying "The truck is fine ".

You might be able to request a stationary regen and pay for it?

But if there is no EVIC error message nor CEL/MIL code, it is probably fine.

 

[6V92TA]

I wish that Ram/Cummins had put a serviceable DOC and DPF like they offer on their heavier duty exhaust systems instead of the sealed unit that they have on these. you can remove the DPF and have it cleaned and re use it.

 

[JR]

^^^Thank Ram for that, not Cummins .
Every Grove/Manitowoc crane I've encountered with a 6.7 or 8.3 that is SCR equipped has serviceable DPF.

I have had my truck display "100% Full Regin Process necessary" or whatever it says. I have been on the interstate every time. The first time I figured "cool" its doing it job. It was the first time I had witnessed the notice. I bought truck with 20k miles and I did not get a regen notice until 38k miles. It now has 42K on it and I have had 2 regens in the last 2 weeks. Every time it happens it clicks down from 100% to 70% in about 5 mins and then says COMPLETE. I read a few posts that said to keep RPMs up, so yesterday I shifted into 4th or 3rd and maintained RPMs around 2200. Still completed the cycle at 70%. Does anyone have any thoughts/suggestions. There are no other lights or problems. Truck runs great...

Mine does that sometimes. But it clears up when I drive several hundred miles. I wouldn't worry about it. I think the count down that you speak of is based on time rather than actual regen completion. Because I have actually had mine regen more than once per week. When it does this, I realize it really didn't get down to 70% completion the first time, and regenerated again that week because it really didn't clean it up the first time.

Your truck is waiting until you get on the highway and probably waites 5-15 minutes after being on the highway before it "decides" to start the process. Keep driving it on the freeway every chance you get just to ensure it is completing regen.

If you are not getting a Check Engine Light, then it is really doing what it is supposed to do. Keep plenty of DEF in the tank, because it might use more during the regens it is doing. It might be actually doing some regens it doesn't notify you about. Taking the interstate whenever possible will help keep your DPF clean.

Andrew, not sure where you live - if it got cold last winter, but last winter here was extra cold and moisture got into the delta P sensor on my 2013 and cracked the sensor so it didn't give an accurate indication of how plugged my DPF was. (I average 150 miles a day, longest constant run is 75 miles.) My truck went through almost constant regins and my mileage tanked. I had that sensor replaced and everything went back to normal. Just a thought.

Just don’t overthink it. Continue driving until you actually encounter a problem.

My truck (2016 3500 SRW) has recently been doing the same thing where I get a “100% full regen in progress” however today I noticed the check engine light came on. I haven’t noticed any performance issues and drive at 65+mph until it shows 70% where it gives me a regen complete. The engine light has stayed on after multiple starts throughout the day. I do not have a scan tool to check why engine light is on. I’m figuring I should get an OBD scan tool, am I correct?

 

[Wiredawg]

I purchased a DPF cleaning system when I reinstalled the DPF on my previous 2009 Ram 4500. I is an aerosol where you remove the front sensor, spray it in before starting, reattach sensor, drive it on the interstate for about 30 minutes, and repeat. I guess the 4500 needed a regen when I removed it and when it sat for 8 years, it pretty much hardened in there. The stuff worked. If interested, I'll go to the shop and get the info for y'all . it worked. Check YouTube as well, they had a video cleaning a Volvo DEF without having to remove it... removing requires baking in some type special oven/cleaner. Anyway let me know. Ron

My 16 does this too. I drove 300 miles straight two weeks ago. I stopped for a break and when I started the engine, I got the "filter full" alert and a check engine light. I drove it around for the weekend anyways. It finally turned off when I was about half way home.

My truck goes in for recalls today, so I'm hoping they can find why it gives me the filter full message even though I'm not a stop and go city driver.
