Automatic Regen too often

That makes about as much sense as anything else I have seen. Lol

Agreed! Cannot recall it doing this before but hard to recall 3 years worth of regens.

Cooler temps coming this week so will see if that changes anything, as others have seen. Also, have a towing trip coming in few weeks so that'll definitely get it to passively regen. Towing and highway trips are the times it has no problem passively regening.

I have an oil sample pending from last oil change, about 10k miles on the oil. Will see how the fuel dilution looks. Did not notice the dip stick reading any higher during that time so hoping I'm lucky and not getting a bunch of fuel into the oil.

I've said it before, I think my truck is working as Ram intended, albeit much more regening than I would like, given I use it as a daily driver without highway speeds. If the fuel dilution problem is not there, then I would think the worst that may happen in my case is the DPF fills with ash sooner than would like and requires replacement due to that alone. I sure enjoy the truck and hope this DPF mess does not impact that any more than just having to monitor it closely.

My truck is operating like yours. If I drive it in town and make several stops, then the gauge will start climbing. Get out on the highway and give it a good 30-40 minutes at 75-80 and it’ll start going back down. Hook to our 7k TT and it’ll go back down to zero on the DPF gauge and get back down to where the ScanGauge is tracking by the timer. I’m at 22 hours and 803 miles since the last regen and the SG is tracking right with the timer DPF gauge came up to about 1/16th and my last UOA showed <2% fuel with 5915 miles. So, like yours, I guess mine is doing like they intended for it to.
 
Here is a fun status... 22 3500 HO with the frequent Regen issue... averaging 160 miles between Regen unless towing. This is with using Archoil over the past 8 months.
Pulled a 16,000lb fifth wheel from Indiana to Florida... 1000 miles... was able to get a 24 hour Regen.
Pulled it home.... and did not add Archoil at my first filll up (about 100 miles into the trip home and was at 1/4 tank). Stopped for the night after 400 miles. Started up the next morning... pulled 15 miles and instantly went from 0 on the DPF gauge to 50% and hit a Regen. Finished within 15 minutes and stayed at 0 on the gauge the rest of the way home.

Got home... unhooked.... next day drove to work... within 10 miles went from 0 to 50% on the guage and triggered a Regen. I'm going to leave the Archoil out for the next month or so to see if I can get the MIL to come on.

Sounds like a plan to me. It’s unfortunate that they won’t do anything for it until the CEL comes on but that’s just about their universal MO.

Try towing in town a bunch of red lights and short pulls My truck really hated that. You will need to get your regen to trigger 3 times about 50-70 miles apart before it comes on.

Second 24 hour regen in a row since the weather cooled off.

871 miles and 24 engine hours.
Average speed of 35.72

DPF gauge on the dash never registered any soot load at all the entire time. Mostly all highway with some short trips and idle time.

DPF % REG jumped to 20’s when the cycle started. Took 19 minutes on the highway at 75mph. I’ll be curious to see what the PID reads when I start the truck back up this afternoon and head home. It was a warmer than normal morning (60°F) with some moderate humidity due to the recent rain.

Still using the same fuel from the same station and the normal Archoil AR6500 1oz / 10gal dose.

Got my first regen since it cooled down some. Humidity is still high but the temperature while doing the regen was 73. 909 miles and 24 hours. Took 20 minutes at 70-75 mph. DPF gauge on 0 start to finish during the regen. Had jumped up half way to the first mark but dropped back to 0 before going into regen. The SG shows .78 for the DPF soot load and .02 for the dp. I think it got a pretty good cleaning out. EGT 3 got up to as high as 1150*. Oil level still in the same place. I think I’m good.

This is nearly exactly what mine does too. I towed 3 weekends in a row during October. The last time I pulled my camper a few weekends ago I went 300 miles on a Friday. Parked for the weekend then after 10 miles or so on the road on Sunday heading home it did a regen. The gauge stayed at zero all the way home. Left for work on Monday and within 10 miles the gauge went from 0 to just under half and went into regen. The other two weekends were similar.
 
my truck is new and all so i don't add to much to this thread. however i have 4500 miles on it. 4 regens. 3 at 24 hours. one at 14 hours. Averaging 1000-1100 miles a regen.

the 14 hour regen happened at around 600 miles. no change in driving. out of 4500 miles, 400 of that was towing in the first 1000 miles of ownership.

I noticed unlike the 2500, the 3500 HO didn't or doesn't get rough sounding when it goes into regen. if i didn't have the dpf gauge up id never have known it went into it. just some side info. I'm currenting 18 hours in and the gauge is at 0.

My truck only did 24hr regens for the first almost 30k miles and then all of sudden it was like a switch flipped and it regularly does a regen every 3-4 engine hours and anywhere from 150-220 miles. Makes no sense

im keeping my good eye on how this truck runs lol. i put on alot of miles so we will see where it goes! i have been running archoil from first fill up
 
Recently had my shortest regen ever. 10 miles, and about 9 minutes. However, as soon as I started the truck again after completing the regen it only took about 5 miles to go up to about 12%. It's been quite wet and rainy in Oklahoma, and so I suppose that could have something to do with it. Just interesting. I have about 8500 miles on the replaced DPF now. Hopefully it's not gearing up for the next failure
 
Well with temp changes (or possibly winter blend fuel?) the soot build up happens quickly. I'm driving over 150 miles a day right now. Soot builds from 0 to 33% within 5-10 miles of leaving my house then takes the entire rest of the day to go back down to 0. This is all along I-35 at speeds of 75+ mph.

Now I also have a shimmy that comes and goes when I drive that can get unnerving if the vibration starts and then hit a bump on the highway. I've done 3 regular balances, and 2 road force balance. Tires have about 3k on them and everyone says they are balancing fine. Not sure what else to look for but it's getting old constantly having issues with a nearly $90k truck

Curious about something not regen related - I've started noticing that I can feel the lockout gear for overdrive engage. I'd liken it to increasing engine rpms on a manual car while releasing the clutch pedal (while you're already moving). Basically it feel like it accelerates for a second while in 6th gear. I used to only notice it when the truck would regen - meaning prior to the DPF issues that was my giveaway that it was starting a regen since I hadn't started watching the regen evic display like I do now. Is this normal?

I don’t know if it’s normal but mine does it too. But I only notice it during cooler weather and when I first start driving after the truck has warmed up some.

Maybe should start a separate thread about your non-regen related issues? Just sayin'.
 
Figured id post an update on my truck since its been acting very strange lately. I was getting regens ever ~200 miles all summer with towing 10k pounds 1-2 times a week. Fall/winter have hit and the temps dropped significantly and its started snowing and now the DPF gauge never moves above 1/4 full and will passively regen back to 0 pretty easily.

However last week I had to go down to San Francisco for a couple days. After getting back to the Tahoe area I get the MIL "Service DEF system see dealer, 150 miles until 5MPH max" This triggered with the dash dpf gauge showing 0%.

I made an appointment at the dealer a couple days later and on my way down the MIL just went away - no rhyme or reason. I still went to the dealer and they could not see any stored codes and had no clue why the MIL triggered and went away.

Fun ticking time bomb to play with - cant wait until it leaves me stranded.

These trucks sure have some pucker factor to them. I tense up every time I drive mine but fortunately it’s doing fine. Every time I drive it I ask myself “is today going to be the start of a nightmare “?

One has nothing to do with the other. Could your DEF have frozen? Do you have the latest DEF software update? It is bulletin 90A.
 
This will be the last update for my truck on this thread. I attached my regen log, and as you can see it is very routine. I’ve gotten no help from my dealer service department other than being told that they can’t help until it throws a code. I reached out to Ramcares and they are useless. The person that responded clearly didn’t read my message or look at my service paperwork and regen log.

I looked exhaustively into trading it in on a Hemi truck or selling it myself. The values have tanked so badly since I bought mine last August that I wasn’t willing to do that considering all the time and money I’ve put into it already. So let’s just say I am taking care of this problem myself for good. I intended to do this eventually just not this soon. Unfortunately it was the best option I had. Like some of you I was sick of staring at the dpf gauge all the time and wondering when my truck was going to break down. Hopefully after this it will give me many years and miles of trouble free use.
