Automatic Regen too often

On my way to the dealer to drop my truck off yesterday and it regen’d again. It said my appointment was for 7:30am today and I haven’t heard anything yet. But who knows if they even looked at it yet. If I haven’t heard anything I’m going to call a little before the service center closes and see what’s happening.

When I took mine in in May of this year it took until August to be resolved. So far I've been told my wait is nothing in comparison. Like you I had no codes, but I had photos and a log book showing weeks of regens every 20-50 miles. Many multiple times a day with how much I drive at times. The first thing they did was a forced regen. Then had me pick it back up. I didn't make it 20 miles before it regened again. So back to the dealer I went. Then they ran diagnostics, drove a bunch, ran more diagnostics, tried another air filter, drove more did more diagnostics, then maf...wash rinse repeat until finally they replaced the dpf. 3 months overall
 
Instead of waiting for the excessive regen code and subsequent fuel dilution push for them to pull how many times its regened with witech and push star to replace the dpf per the TSB.

Wow, well thank you very much for this info. If this is the road I’m going down then there is no chance I’m keeping this truck. If I needed the diesel that would be different but I can get by with the gas truck just fine. I’ve scratched my diesel itch and it was enjoyable for about 13 months.
 
I was really surprised to see this when I checked my oil this morning. I think I'm at around 7500 miles since my last oil change. If I do a lot of unloaded in-town driving my truck will naturally regen early, but I took it for an ~90 mile drive the other night (ambient temps were in the mid-40s) and was able to get the DPF to passively regenerate from four segments on the gauge down to zero. If I pull my boat on the highway (it's light but it isn't aerodynamic) it'll passively regenerate really, really quickly. The cooler temps we've had lately seem to have markedly improved the truck's ability to regen. In the summer I'd never be able to get the truck to go from half-full on the DPF gauge to zero by driving so few miles unloaded.

The best thing I've done since starting to keep an eye on this issue is to buy an OBD-II scanner so I can watch the soot loading and EGTs in real time.

Looks to be just above SAFE.

Where was it after the oil change and was it checked the same way?

The first picture below is what it looked like after first pulling out the dipstick. I wiped it off, reinserted and removed the dipstick again, and that resulted in the second picture.

Since there isn't any oil at all on the dipstick for about the last 1/3 to 1/4 of the SAFE range, I figured the reading was about 2/3 into SAFE.

To answer your question, I checked the oil the same way this time as I did last time and last time I remember being just above SAFE. It's a minor PITA for me to check since my driveway isn't level; I have to park on the street away from my house a little bit.IMG_2818.jpegIMG_2819 (1).jpeg

Mine passively regens nicely while towing as well. If there is anything on gauge it will go down to zero and stay there until I get home. Then as soon as I drive it unloaded it will shoot right up to under half gauge and go into regen.

Just heard back from the dealer and I will be heading down the same road as you. They can not do anything unless it throws the code. The diesel tech actually told me to stop letting it finish the regens when they start, to try and speed up the process and force it to throw a code. I can’t do that, I don’t have the time to pull off the road and shut the truck down to force an issue.

To this day mine never threw a code, but they had it long enough and drove it enough that they knew there was an issue. I also raised a complaint with ramcares, and they helped force the issue of the repair. However with all the changes at stellantis, I don't know if anything like that is even possible

It's their new tactic no code no problem. You do that when there is a serious issue and trying to kick it further down the road.
 
Well, weather has cooled off and the soot levels climb like the last monkey trying to get on the ark... I go from 0 soot to 33% or so within 10 miles this morning. Spent 55 miles on the highway with 0 passive regen...

Mine will only passively regen when running 80+ mph empty. Hook my TT to it and EGT’s are in the 800-850 degree range within 30 miles at 65 mph. I have quit driving my truck if Im not going to be running atleast 20 miles one way. I have a Silverado gasser I use for short trips. Does it suck, yes it does but I only see or know of one alternative. I keep holding off on that to see if it’s going to develop lifter issues.

I have a 1994 Silverado Z71. Ol Blue. My baby. Almost 400k on the chassis. Motor was rebuilt 17k ago (9 years), rear end about 25k (12 years) ago, transmission and transfer case are original from when I bought it 20 years ago with 172k on the ODO. Drove it a whole lot the first few years then 12 years ago started a job with a company vehicle, then 6 years ago started my own business and bought a work truck (2016 ram in 2018). She sits a lot, but perhaps I need to do the same.

I’m retired and my truck sits sometimes for a week at a time. Getting old ain’t for sissies though and atleast once a week have a dr or dentist appointment and picking up meds at drugstore. Makes it hard to schedule enough free time for RVing. I think a lot of the emissions problems are intentional so that people that don’t really need a diesel for work won’t be using diesel pickups for daily driving and short tripping. Im hard headed and love my diesel. Im still looking at my alternatives. Getting rid of the diesel is not on the menu.

Meanwhile I’m over here doing 12 miles to work and 12 miles home Monday through Friday and a few longer trips mixed in. All highway at 70-75mph. Currently 613 miles and 17 engine hours since last cycle finished. DPF % REG showing 70% on the iDash and not so much as one tick of soot has registered on the dashboard DPF gauge. ambient Temps have stayed about 30-40°F in the morning and 50-70°F in the daytime. Very low humidity.
My EGT’s hold around 700-750°F for the majority of the trip to work, and 600-700°F for the return trip back home. I am on track for my second 24 hour regen in a row, since the weather changed. Still using fuel from the same station (Amoco) treated with Archoil AR6500 at approximately 1oz per 10 gallon. (Ratio might be slightly higher due to previously treated fuel)

Our temperatures down here are not as low. 60 for the low and 87 for the high today. But Im 16 hours and 600 miles since last regen, nothing on the DPF gauge and 66.67 % on the ScanGauge (tracking by time). No Archoil in last fill up but had about 5 gallons left mixed 2 oz/10 gal.

Dew point this morning was actually the temperature so we had fog with 100% RH.
 
Picked my truck up from the dealer last Friday. I told them when I dropped it off that it did a regen on the way there and it is noted on the paperwork. They say they drove it and were unable to duplicate. It also says they inspected it and showed the dpf soot level was 0%. Well about 10 miles down the road after I picked it up it went into regen again.

My oil was well over the safe mark so I changed it before our trip on Friday. Only had 5,400 miles on the oil. I pulled the camper 550 miles this weekend and it still did a regen yesterday. Then this morning when I left the house the gauge was on 0. After 20 miles on the highway it shot up to just under half and went into regen again. I am now at 10 regens In the last 38 engine hours.
