At just over 12k CEL, DPF 100%, reduced power. Took it to the dealer, they did a manual regen and cleared the codes.

That will clean them out. If you can rig up a pressure washer that can produce steam and make fittings to keep the pressure high enough then you may be able to do it.

An ASH LOADED DPF is when the filter has reached it's capacity to hold the residual ash left over from regeneration. Here again, removing the filter and blowing it out with shop air simply is not effective. DPF ash cleaning is a process that involves baking the substrate and pulsing it with air. Manually starting an active DPF regen cycle (not an emergency DPF regeneration) Shown below is the procedure to manually start an active DPF regeneration. This is not required under normal circumstances. Use VCDS to enter the engine module as shown earlier. Click on "Security Access" and enter the security code 12233. This should be mandatory on every diesel truck. Its easy to manage, too.
