Seems like it definitely will try to take care of itself while you just happily drive along. I may have cut it off in the middle of a regen, so we'll see if there are any consequences from that.
You're correct. It was regening. No consequences, it'll take up where it left off.

Remember the EVIC will only alert if the DPF is getting stopped up.

I have nearly 1400 miles on mine, I've never seen any message yet, but I also drive 33 miles on the highway to work each day and very little stop and go. So far I LOVE this vehicle!

Sorry to bring this thread back from the dead, but I thought I would just throw out my opinion on the re-gen process, I also posted in the re-gen thread in Jeep Garage. I am a new diesel enthusiast, right now I have a 2013 Passat TDI. And from what I have learned in my short time about regenerations is that you should avoid interrupting them just as you should avoid the black plague. lol. From what I understand, during a re-gen, the turbo is extremely hot just as is the DPF itself, and for you to just turn off your vehicle with the turbo at that temperature assuming 1000+ degrees F, there should be a concern of oil coking within the turbo, which is def. not good for the longevity of the turbo. And I understand a re-gen may occur at an inopportune time, like your late for work, the re-gen is still occurring once you arrive at work, but don't have time to wait for the car to finish its re-gen cycle and you need to turn off the vehicle. Hopefully these type of occurrences are minimal. But I feel a word of caution should be thrown out there, it is bad to turn off the vehicle during a re-gen, due to oil coking within the turbo. The vehicle should be left running to keep that oil and coolant running thru the engine and turbo especially. Just my .02 cents.

We have a Grand Cherokee Turbo Diesel with just about 5000 miles on it. Ours goes through the regen process ALL THE TIME. The latest incarnation I was on a road trip and drove 90 miles at 70mph and the message kept coming back saying to drive highway speeds to remedy. 2 days later I drove home (the car was not used for the 2 days) and it got another 90 miles at 70mph and the message still kept popping up. Obviously it shouldn't take more than 90 miles to remedy itself! The next day, when my husband tried to drive it, it eventually told him that he was not permitted to drive over 30mph (interesting, considering the previous message said to go highway speeds). It actually physcially would not allow the vehicle to go over 30mph. So, it's taken the slow <30mph drive to the shop. It also threw 2 check engine codes about losing communication with the ABS system.....and some other "lost communication" error that I can't remember. Needless to say I am not thrilled about my 6 month old car already being sidelined. I love the car but I fear reliability it going to be an issue with this thing!

Ours has just over 10k on it. The same exact thing happened where the exhaust filter filled up and put the Jeep in "limp mode". Jeep has a rapid response notification out to the dealers for this issue. They needed to apply a software update to the PCM module and run the vehicle thru 2 regen cycles. Call your dealer and let them know this if they aren't already aware. I just got ours back last night and so far it is fine. They put almost 30 miles on it to complete the regens though.

My Jeep has the V6, but my pickup has a diesel and the regen always happens at the wrong time. This is one of the reasons that this will be my last diesel pick up.

I have a 14 diesel, and have 12000 miles on it since March. My miles are mostly highway, with most of them accumulated on my 850 mile commute at 75mph. Twice now I have made the 850 mile drive and had the message pop up the very next day, telling me that it is not very smart about its regen timing and that it's not regenerating constantly while I'm on the highway.

Just my experience.

I've gone through about 12 gallons of the DEF so far or roughly 1gal:1000miles, but my dealer also delivered it 25%full, so actual usage is closer to 1:1500

Apparently there was a "required software update" that caused our exhaust system to crap out. Completely ridiculous. If a software update is so important that it can result in the car going into limp mode and essentially become incapacitated in the middle of driving then it should be a RECALL. How else am I supposed to know about it? I had the car in to the Jeep Dealer for an oil change about 7-10 days prior and they didn't say anything! They didn't even know what to do when we brought the car in after limp mode. They transferred the car over to the Dodge dealership to fix it. From now on I will be doing directly to the Dodge Dealership.
