Pulled the code and it is P2459 - Powertrain - Diesel Particulate Filter Frequency

I've had 3 official regens as notified by the EVIC at the following intervals (appx): 2,650, 3,600, and 3,750. I know I've had a bunch of "unofficial" regens as well. MPG is good this tank @ 24mph per EVIC. I've not noticed any changes in drivability.

I don't make many trips under 10 miles. Work is about 15 miles one way (5 highway). I have two 450 mile trips and multiple 100 mile trips to date. Of the 130 hours of run time, I have 6 idling hours of which there were 2 when the truck was delivered along with 10 miles. In my opinion, this is pretty typical driving.

I'm taking the vehicle in tonight after work. See response below from dealer.

"My tech would prefer you bring in the Ram as soon as you can. This code typically would not appear until a diesel has 90,000 to 100,000 miles"

where in the Evic does it show the regens??

 

[Tim]

only 150 miles between the last two regens. You noted 5 hwy miles to and from work, that would not be adequate to regen. It probably takes about 5-6 miles just to reach the required temps to incinerate the particulate matter.

hypothosis: It sees you are on the hwy, and starts previously incomplete regen, then you exit off the highway before the regeneration has a chance to complete. could this may be happening on every trip to work?

The regens were completed. In each instance, the EVIC displayed a message of the DPF being 90% full. As you drive, the message will count down and tell you it 90% full, 80% full, 70% full ect. until it completes. In each of the three instances the EVIC stated the regens as completed and I saw them finish at either 0% or 10%.

I have the premium display and it pops up right in the middle of the display in bold block upper case letters. There is no missing it.

Like this.

Exactly however I have the other IP.

Bet you have either oil leaking into the turbo or an injector issue. All of these problems used to leave tell tale signs with the color of smoke coming out the exhaust, but now they just plug up the filters. Then when the engine sense a full filter it tries to burn in out with a regen cycle. However, I bet the fuel/oil doesn't burn.

 

[shaker223]

Tech at dealer could not find anything from the codes. Looked at the oil and said it appeared normal for the miles. The oil was still full.

He opened a case with Chrysler and left the codes active. Said there was one other case out there with the same fault code.

You're right about the exhaust clues AWITX. The tail pipe is pretty much spotless after 4300 miles so if there is a problem, It's in the DPF!

Being that the ecoD is not my truck...I have not seen this message, however I did note at one time while driving it the fuel economy dropped to 21 mpg while driving home on the highway, then after a while it went up to 30 after about 20 miles. I guess you have to set up the display to show this message?

Hope they get to the bottom of it quickly, let us know the outcome.

Tim,

You do NOT "set up" anything to get the regeneration message. When it regenerates, the message just comes on.

Noticing a change in fuel mileage might be some indication but I doubt it. The whole thing is over in little more than 10 minutes. I really never noticed much of a fuel mileage change on TWO notifications that my truck did this.

Hey Tim,

Official regens show in the evic and have a chime I believe. Nothing to set up. I too have experienced the "mini" regen several times that you experienced. Driving the same roads everyday to work you learn what your MPG should be normally and when it is off 10 or so, you know something is up.

 

[Tim]

OK, thanks for that info guys.

I asked my wife if she has the message, she says no. Her truck has 4000 miles on it of which 75% is highway.

 

[mattyj724]

i have 2600 and never have seen the message. My Evic has the LCD screen that you put gauges where you want them... not the small black and white one..

Same here.

For those who seen the message pop up, how many miles did you have when the regen message first appeared, and then after how many miles did it reappear?

Your answer for the first of THREE I have had ...in picture.

 

[Tim]

599 miles, so it must be happening but we do not see a message.

It's possible that if you run hard and long, it would not need to regenerate.

I have done almost no long runs and towing. Thing regenerated around 600, 3,000 and now 4,800 miles or close to those figures. Really disappointed I have not run the snot out of the thing but that has not been the case.

Coming up this weekend I will heat and beat this Eco., towing a 5-6,000 lb toy hauler, depending on how it's loaded. It should run so hot that the heat of operation will burn off the exhaust filter without having to inject diesel on it to burn things up.

Time will tell.

My first regen as shown by the premium evic was around 2650 miles. Second was around 3700 and third was around 3850. Not sure why...nothing changed in driving habits.

Have not heard from dealer or STAR since they looked at it last week.
