    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
