Change oil indicator

Yep, no light in the LMM to indicate regen. If your still regening then there s a DPF otherwise you would have raw fuel or fire coming out your tailpipe when it attempts to clean itself. Take a pic of the exhaust system and post it up. More than likely it is present and is soot loaded, the newer systems have a soot diverter to keep the particulate matter from loading up in one spot on the face of the DPF, the older trucks did not and had issues with constant regens as a result. The fix could be as simple as forced regen with the PPE programmer...

Ladies and Gentleman i have to stand corrected I was wrong yes I do have a DPF I made the mistake and was looking from the passenger side vs the drivers side so i couldn't see it in front of the transmission cross member. I've attached some pictures that shows the DPF. I've also attached a pic of the program I use that shows / tells me that the truck is doing another regen. I pulled out the K&N airfilter replaced with stock AC delco, cleaned mass airflow sensor really good. The truck is still going into regen mode often, I just reset it back to stock last night but does anyone have any ideas why its going into regen so much I though it was the mass airflow sensor being dirty but i've cleaned that completely.
Any help will be appreciated and again sorry I was wrong regarding my DPF.

Could be a plugged DPF. I am not sure if people are still getting them cleaned. If the truck was making tons of soot they can be clogged real bad word normal regeneration cycle won't remove it all.
Definitely a stock exhaust there. That being said... I have a completely midified truck, and it is EFI live tuned. I have the same problem with the oil life monitor. I get about 1,000 miles from 100% to 0%. I talked with Duramax Tuner about it, and they said there is nothing they can do in the tuning and not to worry about it and change it at normal intervals. I have been changing mine every 1,500 miles for piece of mind!! Thank god I don't drive my truck everyday anymore or I'd be going broke changing oil!
I'm in no way saying it's good, but Mine is doing it too!

Really?
Man, if youre deleted, & regardless what the oil life thing says, you can go much longer then 1.5K miles.
Question is it possible for a dirty mass airflow sensor to cause the truck to regen sooner meaning run rich and that cause it to have more soot and cause my issue?
Reason I ask is I finally pulled the sensor out completely out the housing and sprayed the crap out of it vs just spraying it when it was still in the tube. I'm stock again and it only did 1 regen all last week vs 2-3 that it did prior to that.

ok so I'm confused now my truck is going into Regen every 120 or so miles so truck is completely stock that is 3-4 times per tank. Anyone have ideas? or Directions?
I'd love to delete but 2 problems I have emissions and don't have a programmer to do it. I already have a ppe standard
