2019+ Frequent Regeneration Issue Tracking Sheet

GitToDeChoppah said:
I was running into this myself on a brand new 2023 3500. I brought it to the dealer because the too frequent regen code threw an CEL with only 1500 miles. It was in regen every 100 miles or so.. They broke the air box while they were running their diag. They replaced it and ordered a new dpf, but it was on back order. They gave me back the truck while we waited for the new dpf and it no longer regens frequently. I’ve driven it about 1500 miles and it only regenerated once, and I think that was the standard 24 hour engine hour regen since the gauge was empty. Replacing the air box must have resolved my issue, or something else the tech did while doing his diag… at least for now.

This could be something as simple as an extra reenforcement rib or lack of one that is causing turbulence in the air filter housing. Glad to see one of the Star technicians checking out the live data feed to hopefully figure out exactly what the issue is. I’ve not had a single regen that wasn’t on the 24 hour mark since changing the air filter and making sure the fuel I put in the tank is B5 or less. Doesn’t matter what the fuel is towing but the gauge jumps up fast just running around empty between towing legs of our trip with the B10-15.

Did they change out just the air filter box or the ducting also that leads up to the Ram Air scoop on top of the radiator?
 
My Ram 2500 with a DOM December 2022 is at the dealership at this moment for this exact problem. I did notice it in regen often and thought it was normal. It was previously in the shop last December for a rear main seal that I noticed at only 500 miles. BTW it was at the dealership for like 2 months. Should have Lemoned it then. The Truck currently has ~11500 miles. I'll get back to ya after the dealership is done.

@mbarber84 Great work!​

 
Question...How do you know when the truck runs a regen cycle?
I have had multiple CEL's for emissions and my DPF replaced twice with less than 10K miles on the truck. Both times it went into limp mode. Both times right before a trip. So far the truck only has 10K miles on it.

If you have your DPF % pulled up on your Evic display, it will say “exhaust regeneration in progress”. Happens at 45% soot load on the gauge and or every 24 engine run hrs.
 
Watching the gauge now...Dealer just changed my MAF and the truck runs better than it ever has. It does jump from 5% to 10% to 20 and 30% but always goes back to zero. Limp mode episodes and CEL's seem to have subsided.

Which MAF did you have, and which one was installed as the replacement?
 
My sensor was replaced with P/N 68444077AA
I think this was an issue with this truck from new. The truck has NEVER run as well as it does now in terms of power and smoothness. A big thank you to @mbarber84
 
Just joined this forum after researching my 2019 HO6.7 frequent regens. I have almost 100k miles on my truck, but have been getting kicked down the road at my local dealer with "parts are not available to fix it" for a while.
 
I am sorry to say that Ram is not being responsive to my issue. I am losing revenue and opportunities with an unreliable vehicle. And this is the second time in a row with Ram. Very expensive and very frustrating.
 
My truck usually regens every 8 to ten hours and around 400 miles. last trip towing 8000 lb. travel trailer it went 34 hrs. 1529 miles. before regening next trip towing same trailer with a bit more load on hunting trip Alaska Hwy. it has gone 55hrs. 2224 miles without regening yet. I know its passive regening but i thought it would be 24 hrs. max. Not so with my truck. 2022 HO 6.7 longbox limited Canadian Truck.
 
I am aware that it only takes 20 min. When towing to do a passive regeneration. So I monitored it frequently looking for 24 hr. Regeneration. Never showed any percentage build up on gauge or message that regeneration is in process. But I guess I could have missed it.
 
And now I am told I have the lifter failure issue at 11k miles. Cant beleive my luck with Ram.

Hopefully they’ll replace the whole engine.

I am told that unless there is a catostrophic failure of the engine, the only fix STAR authorizes is a replacement cam and lifters. Collateral damage from steel contamination in the rest of the engine is appearently no concern to Stellantis.

Be sure that they check the lifter bores. Another member on here had lifter problems and they had to change the block also.
 
I got my best ever regen results this past weekend towing our 7k TT. Got the 24 hr regen about 45 minutes into the trip. DPF EGT’s stayed in the high 700* to low and mid 800* range for the whole trip after the regen. When we pulled in to our destination, the dp on the SG was reading .01 at idle. Was also running the performance dose of Archoil 6500. The truck has 17k miles on the FleetGuard air filter which I will change before our next trip in August. I feel for others having regen issues with their trucks and it causes a lot of anxiety wondering if and when mine changes but right now it’s doing great. I changed the TBAP sensor out in September of 24 @ 16,568 miles and I have had nearly 0% reading on the EVIC DPF gauge since and only 24 hr timed regens. Apparently the MAP sensor gets its base pressure reading from the TBAP sensor. IDK. Truck is running perfectly at the moment.

TBAP sensor?
