The correct way is to to physically pull off the DOC and DPF and have them baked, de-ashed, and flow tested. Then after re-installing them, perform a DPF replacement procedure in Insite to reset all the soot counters in the ecm.

That is what I did, even had them flow tested again after being re-cored. We then used insite to perform the dpf replacement procedure. But as long as it shows the ash at 0% it will build soot level so fast it wants to regen every few miles. I am thinking this is what led to the dpf failing in the first place.
