After I shut if off in the garage I could hear that "ticking" sound you hear when a hot exhaust is cooling down and the thing definitely smelled hot. 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.
