Does the GM let you know when it is doing a regen? Or do you guess based on fuel economy?


As mentioned above, no factory gauge indication will "tell" you it's in regen.

When on a trip, the avg MPG will tank by about 2 mpg during regen. That's another way to tell.

I have an Edge Insight CTS2. I have it set to display when the truck is in regen.

or in drive at a stoplight. rpm is around 800-850 during regen at idle in park, neutral, or in gear.


Ditto

If I pull up to a stop light while mine is in regen, I can tell it's in regen based on the slightly different sound as well as higher RPM.


My truck will regen consistently once per tank of fuel, though it's not an L5P. Mine is an LMM

Maybe the truck wastes less fuel doing two quick regens at 250 mile intervals than what it wastes doing one longer regen at 500 miles?

My bet is that the programming change of initiating more regens is because our trucks seldom enter into a situation where they can do one long complete regen before we either reach our destination or enter into traffic conditions that interrupt the process.

But when the process is interrupted, it resumes when the truck is driven again.

When Ford starts a regen that gets interrupted the regen is canceled till the filter reaches 100% full before initiating another attempt. If someone uses their Ford for short trips they might run the DPF from 60 to 100% full and never gett a complete burn. I don’t know if that matters but it might be better to use the bottom half of the filter instead and keep it clean.

I had my 2019 updated and can't say it has effected it negatively at all. It seems like about every tank of fuel it goes into regen mode. The regens on my 2019 seems shorter than my old 2013 Chevy I had.

That’s the way mine works, and there have been a few trips that just weren’t allowing a full regen to occur. It’s maddening to see that happen several times in a row. I wish when the DPF gets above about 80% soot load, it would allow you to start a manual regen. There have been too many times that if the ECM would just start the regen at the beginning of a short trip, it would have plenty of time to finish by the time I reach the destination. Instead, it seems to wait until just a few minutes before I get to where I’m going. Then it only has time to burn off about 10% of the soot.

This thread has been interesting and a learning experience for me. My 2020 Duramax and first diesel vehicle was idling high yesterday. I thought it was too warm outside for it to be idling higher than normal. Now I understand why! Thanks for teaching this old guy something [emoticon]

If you have a Chevy you can use a Edge CS or CTS to monitor and initiate a regen, I have soot level, miles since last regen, as well as exhaust temperatures. It will also data log and read and clear Codes. I keep an eye on my soot level and if I am getting up there and driving more than 30 minutes I will force a regen.

To the op,

I would give it a regen or two before getting too worked up, I have had my Edge CS monitor since the truck was new and would get between 450-500 miles between regens depending on driving. I had an unfortunate issue when a drill bit got away from me and I ended up with a hole through my airbag module, I took it in to the dealer for that and they did the update for the regen cycle while it was there.

My next regen cycle didn’t even go 300 miles and the one after that about 400 miles, I went back to the dealer and complained to the service manager and was told nothing they could do. Since then I have gotten up to 720 miles between regens and it usually is around 650 plus or minus a few miles.

I think as mentioned above it needs to get some running data before things even out.

I know that when my trucks were new, a regen happened pretty fast. It is said that is how they are programed..
So to me, it would follow that a reflash could cause the same behaviour.
