DPF QUESTION

You need a scan tool that will do a forced regen at idle. Or you need a scan tool to clear the codes. Hop on the freeway where you can go 70mph constantly and keep clearing the code as they come back. It’ll take 30/45 min do not stop when the check engine light stays off. Let the truck complete its entire regen
if you are in limp mode then you'll have to do a service regen. for this you will need a decent scan tool as mentioned above. EfiLive, Tech 2, etc. or take it to the dealership.
if you remove it and clean it, the ECM wont know that the ash load has been reduced or a cleaning has been done so it will remain in limp mode. you will still need a way to clear the codes and get it to start a regen process

It should be able to detect the spot loading. Pretty sure that's what the pressure sensors before and after the DPF are for.

I've taken mine out several times and hand washed it. was never able to get the computer happy unless I also ran a service regen to get it to reset the DPF
