First regen today. 35k miles.

Never having the warning is significantly different than claiming to never having a regen. I've never had that warning either, but I've definitely smelled regens.

I pulled off my muffler two summers ago, and then two winters ago I was driving around in the snowy weather we had, and didn't even realize what a regen smells like. I didn't have my horse stall mat installed at that point, but I did have the tailgate removed along with all of the train plugs.

I'm going down this country road covered snow, sliding all over the place, then all of a sudden I have this feeling that I can't breathe, and all I can smell is bleach. I had all the windows closed but the tailgate was open. I opened the windows, and the smell wasn't going away. I was driving slow and I initially thought I had driven into an area that had some sort of chemical leak and I was going to die. Pretty quickly I went into fight or flight mode and that's when I realized that I was going through a regen, and my first thought was drive faster to get it out of the vehicle. Thankfully that worked and I'm here to tell the story too.

You might think that I went home and fixed up the Jeep so that the smell wouldn't come through the floor at all, but if you thought that, you really don't know me. All I did was inform the wife when she rode with me that if she starts feeling she can't breathe open the window.

At this point I have the horse stall mat installed along with a aluminum sheet underneath it and it does it pretty damn good job of keeping the ammonium out of the cabin. You'd think at some point I would add a extension and a downpipe on the exhaust, but I actually have other plans for the exhaust pipe in the future. So for now, I just know enough not to die. ?

this is not true.

Really? 18K miles, lots of regens on an SG2 and SG3. Not a peep from the jeep.

Elaborate please.

Buddy said the Jeep gives no indication of regen but it does it says “dpf nearing full regen in process keep driving at a consistent speed” blah blah blah…

Thank you. You confirmed my original comment. This is because you've interrupted too many regens. Hence... An issue.

Beep boop blah blah ?

I’m not sure I don’t monitor my regens, no point. Not really sure I’d say an “issue” just the Jeep doing its thing.

As @GtX said:

The JL gives zero indication when a Regen happens unless there is an issue.

In this case there was an issue. Unless there's an issue there's nothing on a stock dash to let you know that a regen is occurring.

I don't like it either, but the emissions equipment on modern diesels needs to regen whether you're driving highway and triggering regen at the computer limit of mileage or engine hours or drive around town and the soot load sensor triggers regen.

If the vehicle is telling you that you need to keep driving it's because you've interrupted too many regens and the vehicle is concerned. In my book, seeing this message is an issue. Your rig, YMMV.

I get it I just feel like since there’s nothing you can do about it what’s the point of monitoring and that kind of stuff, basically if you are driving like a long stretch you would never see any messages cause the system will be functioning properly? But when you day to to day the system never meets requirements with temps and what not it will just tell you when your filter is nearing full capacity and absolutely needs to perform the regen the function properly?

Yep, that is exactly how it behaved on mine. Except, mine did every 750 miles or so. So it is based on engine hours I guess if we never exceed 80% STM. If you do more highway, your distance since last regen would be higher than someone who does less.

No one has come forward with the info on the 3.0L hours/miles that trigger a regen, but I'm pretty sure there is a threshold of some kind. The Cummins will regen every 24 engine hours like clockwork if the DPF has not loaded up to 80% (I think that's the trigger % for the Cummins). Mine has the DPF load gauge and it has NEVER come off 0% because I run at highway speeds and tow regularly. Guys on the Cummins forums say the hour trigger is just to cycle the system and make sure everything is working as designed.

Yep. This also could be another reason.

In heavy equipment an active regen will happen based on time since last regen as well as the normal for soot loading.
this is to prevent soot packing in the outer circumference of the dpf when the engine is operated properly and passive regen keeps the center flowing well. I’d say jeeps use the same strategy.

When mine goes into regen my SG3 alerts me and I drive around until it finishes.
