EcoDiesel's Achilles Heal...

[rickinAZ]

...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.

Did you ask what the out of pocket cost is for this replacement and labor? That would be interesting to know. Most of the time I do shot hops around, but I get around 1,000 miles a month on my ED. I may be in the same boat as you, but not quite as fast!

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.

are you saying you havent had a regen in 35K?

Your Jeep has had regens.

You've had lots of regens. The Jeep just doesn't tell you about them. It's only when you are interrupting the regens too often that the Jeep tells you to keep driving so you can complete one.

If you use an aftermarket monitor like a scangauge or Banks iDash, you can watch the "silent" regens happening.

If you never see a warning about a regen that means you are letting them complete often enough, and that's a good thing.

Hmm, maybe monitoring DPF flow with Torque isn't enough to detect silent regens? Sorry for looking like a jerk.

You're not a jerk. Everyone starts off not knowing the details.

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

For those who believe that they haven't had active regen, are you actually monitoring the situation, or is this just your seat-of-the-pants impression? Just to be clear, without a gauge, there is absolutely no way to tell that it's actively regening. As it came from the factory you are flying completely blind. The Jeep only notifies you just as you are about to hit a Titanic-sinking iceberg. If your engine was always under constant load (hot + uphill + pulling trailer + 80mph + long stretches driven) I could understand, but I suspect that's not the case.

Come on guys, come clean. You just THINK that it's not regening.

If after the eight year warranty is up, and I still own the Jeep, I am totally okay spending $2K out-of-pocket every four years for a DPF replacement - and I'm the worst case scenario.

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

Sorry to jump in. How does one know the regen happens ? Is it automatic ? I understand a scanner will tell. I’m at 18k miles (22) and never seen any dash icon for regen and with the banks derringer which has the I dash I have not seen or been able to scroll to a “regen” options.

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.

Likely he deleted it.
