    While driving my 2016freightliner cascadia, the little yellow light on the engine occasionally came on and the mechanic checked it with the computer and told me that the DPF filter element was not good. So I found the maintenance man to clean it!
    But it feels even worse. In the past, it was necessary to exhaust smoke once every two days or so, each time about 45 minutes.
    But on the first trip after the cleaning, it leaves Friday morning and exhausts smoke on Sunday morning. Next, one on Wednesday, then one on Thursday/Friday. It makes me feel depressed.

    Yes, regeneration. I don't idle it, and on my last trip, I slept with the engine off at night.
