I don't know anything about cleaning or washing the SCR. But I sure would like to know how or why it got soot clogged as I never heard of that before.

Well I just bought the truck a month ago. The craziest thing is that it was just replaced in June under a recall from what the car fax says. So I called the dealer that did the recall and they confirmed , ask them about warranty. They told me yes but the only time they have seen this is if the truck has a tune on it, and if it does it would void the power train warranty. The truck only has 35K on it, and I have no clue if there is a tune on it. I ask them how can they tell and they said by the number of key sets on the ecm. No way of me seeing that before I take it to them.

Interesting and a bit confusing
I've never heard of a tune effecting or clogging the SCR.
I've never heard of an SCR recall
However, I'm far from being all knowledgeable.

Not sure whats going on with it. Mechanic pulled SCR off and tried blowing it out and nothing but white ash, no air would even pass through it so now waiting for new one. Truck ran great for the short time I've had it. Took it from PA to NC no trouble got 28MPG down and back, then coming back from OH heard a big air leak thought I was getting a flat, pulled over and had to call for a tow. Never thought it would be a hard part to get but seem to be.

That makes me wonder if someone didn't gut out the DPF filter. Ash should remain in the DPF.

Ash accumulates in the webbing of DPF, It can flake off and be dispose of VIA exhaust, its a good practice to place your DSL engine in Stationary De-soot once every 6 months or 10K miles.
When it fills the Honey comb Webbing your screwed, it takes Qualified expert with chemicals that are NOT readily available to thoroughly clean it out.

Interesting. I see the SCR online but they have a core charge. Is it possible to cut out the cat and reweld a new one in? They had the DPF off the truck to weld a new flex piece on it because it had a crack in it. You could see that it wasn't hollowed out, dirty but not plugged.
Is there a way to clean the intake with pulling it?

Do you mean 'without' pulling it? If so, BG has a cleaner that is used while the engine is running. Some dealerships offer the service.

Carbon in the intake can be a problem, but typically you're good for 100,000 miles or so. As long as I'm under the AEM warranty, I'm not going to worry about it. Once my AEM warranty expires, then I will remove the intake, replace the coolant hose that is under the intake, and install a new intake. Then I'll be good for another 100,000+ miles. A new intake is fairly cheap.
As for a tune, I have the GDE EPA Compliant Tune. It will certainly give you a cleaner combustion. There are tunes that will delete the EGR function, but those are not legal in the U.S.
I had a similar problem. White ash in the tail pipe. The DPF was plugged and the filter material had broken into small bits and clogged the SCR. The DPF was toast and the SCR could not be cleaned to allow adequate air flow. I filed a claim and both the DPF and SCR were replaced under the 80K mile federal emissions. warranty. My truck only had 45k miles when this happened.

Did they say why that happened? I sent the receipt from the mechanic to the dealer and the dealer said that the part number they installed did not match the part number they installed. I ask my mechanic about it and he said the part number he installed is the correct number for the SCR the truck requires and that is possibly why it went bad in less than a month. I believe my mechanic since they specialize in diesels engines and he also drives a ecodiesel Ram. He said he could not get the part number off what they installed since it got too hot
Mine was a cluster. We are not sure why it happened. Never had the dealer look at it because they were booked out for over a month. My indy shop took care of it. Stellantis approved it since no dealer could get to it for a month. Stellantis paid for parts only which worked out ok for me. Coincidentally my neighbor manages a Firestone a repair shop and had the same model and year truck come in last week with the same problem as mine. He sent them to the dealer.

Yesterday I got a P2459 DPF Regen frequency...plugged in scanner and drove with it and soot sensor was at 100%. Watched it go into regen and drove it hard to keep temp up and sensor never dropped until after regen was complete. It went to 74% for about 30sec and then back to 100%. Would I be correct to say its a bad sensor and if so where is it located on the exhaust.
