2022 Ram 2500 6.7 DPF Filter 100% full.

[Herefishy]

The truck was reading the PCM after I installed the bypass plug. I followed the instructions and tried to initiate the regen. The software said there’s one bad parameter and that’s because the codes aren’t erased.The truck is still drivable it’s not in limp mode yet. It has 55,000 miles. I’m to blame for this because I wasn’t monitoring the DPF filter. I have a local company that’ll clean it for $350. Any advice on removing the code now that I have the proper Alfaobd software.

What a helpful place.

I find it amazing that a '22 with only 55k miles could have a full DPF.
Perhaps a faulty sensor?

OP, maybe try not using it as a grocery getter?

And you know this , be kind , guy has a problem. Might try to help him , not criticize .

I was trying to help him. Use the truck for it’s intended purpose.

Intended purpose? What section in the owners manual does it list that? My '18 CTD 2500 never had any issues with town runs. My '22 is whole different story.

I don't think so. Folks have had the DPF's scoped and they are indeed clogged. Just my opinion, but I think they got a bunch of bad DPF's into the factory for the 22's. Probably a new, lowest cost producer. The tech bulletin they put out about says to replace the DPF's.

And just what is the intended purpose ??????

It’s a pretty well recognized concept that the emissions control crap on modern diesel engines doesn’t like it when the engine is run under light load for extended periods or repeated short trips where things don’t get up to normal opearting temperature, so the “intended purpose” would be the opposite of those things.

The DPF at 100% might be trying to do a regen so, if it is then try driving it hard at high speeds and maybe it will sort itself out. The DPF filter is a known weak spot. To keep it happy it helps to drive it until the exhaust system is good and hot. This is way linger than it takes to get the thermostat to kick over.
All engines put out more particulates when they are cold. So installing a block heater can help a lot. Getting the engine temperature up before the truck starts can lessen the amount of crud that gets into the filter. The DPF filter is trying to intercept these particulates and then burn them off at higher exhaust temperatures. But at some point the residue just becomes more like welding **** and won't burn off. I am skeptical of a claim that the DPF filter can be effectively cleaned. Do they offer a guarantee?
It is expensive to replace. It isn't super common to have to replace it at 55,000 miles, but if the truck is run cold (the exhaust system, not the engine temp) it will happen faster.

"Its intended purpose"?

I bought my 2022 used, from Carmax, with 35,813 miles on it. At about 37,200 miles, I got the "DPF full, see dealer" message.

DPF had to be replaced, and was (Ram covered it under warranty) BUT, it took over 30 days to get the new filter.

Since then I've been watching it closely. It has seemed to regen itself and have not even seen the "Keep Driving" message until last week.

When it showed up, I drove for about 20 minutes and it cleared.

My driving habits are, roughly, 1.25 hour round trip, highway miles each week. Two short trips to the gym, about 1 mile each way, each week. Occasional but other rare short trips during some weeks.

I was told that 2 hours of highway driving each week should be sufficient for it to keep itself clear.

I run Archoil in every tank full of fuel.

After it cleared itself, I parked it. Next trip was 1.25 hours, highway, and the DPF filter showed 12.5%. Next trip was 35 minute highway (to get tractor fuel) and 35 minutes highway back and the DPF showed 25% full.

Next trip was 1.25 hours, highway and the DPF filter shows 37.5% full.

I'm driven 33,378 miles since the last DPF filter was replaced (the first one had to be replaced at 37,200). This certainly doesn't seem like what anyone should expect.

Perhaps none of this is really a problem but, at this point, all I can do is watch and hope.

I've often wondered, however, if they are not meant for "short trips", what do the service trucks (plumbling, electrical, other contractors, etc) do? They are mostly around town and, I doubt, doing a couple of 1 hour trips on the highway each week.

Clear the codes using alfaobd. Engine off, selector set to run. Then after that it may start the performance test needed for the regen to start. Not always guaranteed, sometimes the truck software just doesn't want to cooperate.

Once it does start, let it run at least until the regen finishes, which will be when the rpm drops back to idle. The software may eventually say that there was some error and it stopped, but then you can take it out for a good drive at highway speeds. If it starts another rehen then, just keep driving until it finishes, the performance test doesn't seem to trigger the regen finished process properly when it aborts.

The biggest problem with DPF or the SCR canister is people tend to let there trucks idle for long periods of time, with this extended idle time the engine runs cooler which exhaust is cooler which plugs up the DPF. I have a 5500 that I use as s mechanics service truck. It turned over 1 million kms and it is still running on the factory DPF. The idea is to keep the engine warm or operating temperature. If your light comes on, chances are your engine is running cold. On long drives if everything is working correctly the DPF should clean itself. As far as taking it off to clean it we have done numerous Tractor/ trailer units but I have not found any one to clean the automotive side. On the heavy truck/ equipment side the manufactuer requires it to be done at 5000 hrs. Were in the automotive world that is a lot of idling time to get there

All those type trucks around here are gas not diesel. Most likely to avoid those problems.

Usually the ECM will not let it get up to 100%. If it gets this high it will mean you may have a sensor failing or not reading properly. Usually , on mine anyways if I'm running equipment from my PTO the DPF will climb but has only kicked on my light twice in a million kms. When it did once I got the truck moving to about 60Kmh it started a burn and cleaned the DPF. Then I was good for another 6 hours of stationary running. After stationary running equipment on my Service truck it does a burn as soon as I get moving

Hi Guys
First it’s not normal 55K/miles truck shows DPF full, Second check the sensors and electrical tests, if you can check with camera DPF if you confirm everything is right than you’ve to replace it.
One more thing what codes shows in display also Alfa obd don’t work this tests. Get good scanner like Autel Comm, Zeus
