My 2014 CTD had 18300 miles on it when I bought it last month. It now has about 1100 more. This morning, I noticed the fan running when I shut the engine off. I recalled from reading this forum, that this might mean a regeneration was in progress. So, I got right back in the car and got on road. I also recalled the tip about setting the instant mpg to metric and noting whether the decel mpg showed 0.0l/100km. During the various times I'd tried this in the past, decel always showed 0.0l/100km when coasting. This time, it would bottom out at about 1.4l/100km. After 15 or twenty minutes, it went back to showing 0.0. I concluded the regen had completed.

Thanks to you folks who shared the tip about the metric instant mpg. I think you just prevented an aborted regen.

I understand that, but had I aborted this regen, then made a few more short drives with incomplete regens, I might have gotten a DPF that went past the max threshold for a regen. That was what I was trying to avoid.

You can abort regens as many times as you want without issue. The only risk is if you abort a regen when it's first getting started (pre-regen). It's a rare event, and only ever happened to me the first time at 115K miles of driving.

Don't worry about it. The car will handle it all on its own and it will let you know when intervention is necessary.

Just for the record, when you shut the car off and the fan is running heavy duty, I have had regens complete as I drive in my addition and then I drive a half mile to my garage and the fan continues to run after I shut the car off, my theory is the regen in this case is complete, I have a 2 on my scangauge, but the DPF is VERY HOT and the fan is cooling everything down.

You may want to invest in a scangauge II, it will tell you for sure if you're vehicle is going through a regeneration cycle. It also monitors a ton of other useful information including how much soot has built up in your DPF, exhaust gas temperatures, boost, etc.

This thread that diesel linked above explains why it may be a good idea to purchase one if you haven't read it.

I decided against the SC because the presentation is much too antiquated and not particularly intuitive, although I have no doubt it's an useful tool. However, if Linear Logic comes up with a more modern interface, I'm all over it.
I'm still debating whether to try the Edge CTS2 again, as it's possible (and likely) that the one I received was faulty.

Scangauge is pretty basic, honestly if Chevy showed me when the regen was going to occur and all I wouldn't own the silly thing, I ONLY own it because of a design flaw of the manufacture. The flaw is a very short time during pre regen if I turn the car off it can cause a need for a manual regen. I wouldn't own the scan gauge if it were not for that. The scan gauge isn't sexy or anything like that, just a tool to keep me away from the dealer when possible.
