I purchased a used 2020 3500 HO SRW in January. I used to own a 2019 tradesman, and basically traded up to a Laramie. I never used to watch the DPF gauge or regeneration on the old truck because it almost never happened (every 24 hours, and the gauge would never come up). As such, I pretty much ignored it on the new truck as well.
In late February, I got a check engine light; p2459, DPF regeneration frequency too high. I bought it to the dealer right away.
They ran a manual regeneration, said "it's good to go", and send me on my way. On the way out of the dealer the DPF gauge started coming up right away; it was almost fully blocked again by the time I turned around and brought it back. They took the truck again, and (after another 5 day wait), said they performed another regeneration, drove it 30 miles, and it's good to go.
Once again, as soon as I left the dealer the gauge started coming back up again. I brought it back, and was basically told if there is no check engine light, there's nothing they can do and there's nothing wrong with the truck. I told them I had a check engine light (DPF regeneration to frequent), and the problem still exists. I'm sure after a certain number of regenerations the check engine light will come back on, but now I'm stuck driving around having a regeneration every 100 miles until the light comes on.
I'm very frustrated by all this; the fuel mileage obviously suffers, I hate having the truck run high-temperature all the time, and the whole mentality of "no check engine light, it's not broken" is very frustrating.
Any ideas?
Here is my regeneration log, if you're interested:
59,816 (by the dealer the first time)
59,864 (by the dealer the second time)
60,002 -> 60,028
60,116 -> 60,133
60,214 -> 60,249
60,350 -> 60,371
