    Freightliner with dd15, It regens for about 45mins, everything seems fine, but it still has "high soot level" code when finished. Can't clear it.

    I cleaned the Delta P, can't get the temp sensors off the dpf as they are rusted on. But it's Reading temps so I don't think that's it.

    Pressure pipes look clear.

    Any ideas?

    Anyone know how long you can drive once the dpf light starts flashing? How many times can I hit the shut down override? Lol

    Yes, the DPF filter. Has it even been cleaned? How many miles since cleaning? Many say clean 200 -400k miles.
    "Pressure pipes look clear." Blow through the pipe to make sure it is clean and not plugged.
    In the other thread you commented in, High Soot Level DD15, read post #5.
