EcoDiesel's Achilles Heal...

Likely he deleted it.

Also a great option if available to you.

If you have an iDash/Scangauge, scroll around and you'll find a metric for regen yes/no. Alternatively, if you use a exhaust temperature metric, watch for the temperature to exceed to 1,100°. The high temperature is the surest way to tell that an active regen is happening. There is no indicator on the Jeep's dash itself except the one I mention in post #10. And...that one is basically "this is your last warning". It's for when you've inadvertantly terminated regens one too many times. You DON'T want to see that warning. Buy a Scangauge/iDash. It will open a whole new world to you. They should be standard equipment. Good news: they're cheap.

Alright. Thanks for the explanation. I never deleted anything that states “regen” I will check my I dash and see what’s up. Thanks

Because you haven't had a diesel for 15K miles.

No I just haven’t had an SCR or DEF for 15K.

For me, one of the parameters I monitor on Torque is DPF Differential Pressure sensor, and it's always been relatively steady at a very low value. I also monitor EGTs and haven't ever seen them at values that can't be attributed to load. Granted I do pay more attention to driving than logging, heh.

I guess that doesn't mean I haven't ever had a regen cycle. Unfortunately when I was trying to pull logs on Torque, the logs I have access to don't actually have any logging for the PIDs I have it configured to log.

Wow, yes Diesels hate short hops, but I'm surprised to hear you're only 18k and experiencing this. I haven't yet had a regen at 35k, but fewer short hops and more towing and high-load scenarios like off-roading helps.

Willing to bet - YES YOU HAVE, it constantly does passive regens while driving and full regens around 80% (I believe) capacity of the DPF. There is not always a "message" drawing your attention to it. If you had a scangauge 2 or 3, or similar. You would see this.

 

[SargeDiesel]

I can confidently say I have not had a regen in the last 15K….

You've had almost constant passive regens. That is how you keep your DPF % down. Once at a certain level, you get a full regen promise, you've had them.

 

[SargeDiesel]

For those who have a scangauge 3, is the PM11 fill level... the DPF% ?

My PM11 fill level all the sudden stopped working, I am trying to figure out how to properly do a hard reset.

Any suggestions ?

Sorry it was a joke my SCR has been sitting in a scrap pile for the last 15k.

You got me... ha ha... I m a little slow sometimes....

I programmed the x gauge for soot into my SC3. I know it's supposed to have automatic x gauges but I couldn't find one I was happy with.

I have the Banks iDash and when the soot level gets to 80% it does a passive regen. It does not take very long to complete and it gets the soot level below 10. My opinion is thew banks gauge is worth the $$. I used the Banks pod mount - easy install.

 

[zouch]

curious; did you do the upper or lower pod mount?
do you have any other Banks goodies?

If you’ve driven more than 750 miles you have at least had an active regen initiated.

The system is set to regen at 80% dpf or 750 miles whichever is lower. You can see this happening in a scanguage II from my experience.

With aftermarket gauges you can see what is happening and ensure you are burning down below 10% at every active regen.

Failure to do so shortens the life of your dpf filter. So you can continue to to trust jeep and that should last till the end of warranty…

I used the upper mount pod and I only have the iDash gauge (for now).

...is short hops. I have 18,000 miles and I'm taking it in for a new DFP. I drive almost exclusively short hops (5 miles). I'm retired, and all of my activites, friends, and relatives tend to be within spitting distance. I have another 4 years of emissions warranty so it won't cost me. To be truthful, if I keep it past that, the power delivery will make me more than happy to pay out-of-pocket. The symptoms were active regens taking place twice as often as usual, and soot% bouncing up and down by 10 percentage points where it used to just march up 1% at a time. Yesterday it threw a P2002 code but it drives just fine. I am the antithesis of the typical diesel driver, but that low-end torque is worth it to me. I have it modded just where I want it, it's in great shape, and switching costs will be 10X the cost of replacing a DFP. Switching costs tend to be the thing that most buyers ignore (at their peril).

Still a very happy owner.

I used to have a 2016 Jeep Patriot, and for a while there I lived across the street from my job. I love driving so I would drive it to work anyways, 500 ft to work, go out to lunch, less than a mile, come back to work, drive 500 ft back to the parking garage.

My battery died quite a few times while doing that. I had replaced the battery like three times in one year. I couldn't figure out what the hell is going wrong, and then my dad told me that the battery doesn't have time to charge if you're doing short hops all day everyday, so I started putting 10 mi on it every night after work that I decided to drive it, no more battery problems.

Short hops aren't good for any vehicle. Vehicle strive on long distance highway driving at speed.

Unless you have a full electric vehicle, I wouldn't take any gasser or diesel on short trips only. Or at minimum do like I used to do and take it on a 10 mi round trip at Highway speeds at least two or three times a week.

These diesels live for long distance highway speed driving, do yourself favor at least put some miles on it on the weekends. Your DPF might be going now, but later it's going to be your engine. I wouldn't risk it. I'd say you should sell it, but you'd be doing the next owner dirty.
