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.

You may want to check in the Alfaobd forum here. I don't use that, so no help otherwise:

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.
