DPF Regen
I posted this on the 1999 to 2016 Super Duty forum (https://www.ford-trucks.com/forums/1...gen-issue.html) but thought I might get some more insight here -
Some background:
April - CEL came on (P20BA) - ordered a replacement Bosch heater but don't have it installed yet, assumed with the warm weather I'd be ok
July 9 - Turned on the DPF % screen using Forscan , watched the percentage climb until it read full over a few weeks.
July 28 - I get the "drive to clean" message
July 28 - Verified codes using Forscan, only ones listed were the P20BA on the PCM and OBDII
August 25 - I still have not gotten the percentage to drop. Taken several drives around the 30 mile range. My status screen has change from "Full" to "Overloaded" also have the "overloaded drive to clean" message, the truck tries to regen every time I drive so mileage is around 12mpg. I am now also getting messages calling for an oil change and coolant check due - both much earlier than expected truck has ~79K on it, I changed the oil at ~77K and checked coolant at ~67K
I'd appreciate any suggestions

Cleaning message now comes on every time I drive.
July 25 - Tried doing a static regen using Forscan - it failed to complete in the allotted timeJuly 28 - I get the "drive to clean" message

It sounds like the DPF is completely plugged. It could be a sensor issue too, but that's a longshot. There are companies that can clean the DPF once it has been removed from the vehicle. That's cheaper than replacing the entire assembly.

What did the DPF % change to after the static regen?

I'll look up cleaning services, I assume I could also just buy a used one from someone who deleted their truck?

Buying a used one would work, as long as it is the same. Pickup and chassis cab have different configurations.

This is one of those times it has to go to the dealer for proper diagnosis. You don't want to be driving it around with an overloaded DPF it can cause engine damage due to the increased back pressure. My guess is the same as Jim's probably a plugged DPF but that's a bit early for a 67k truck.
What kind of driving conditions has it been subjected to in those 67k miles?

I bought the truck with just over 45K in May 2019 - unknown usage prior to that. So I've put on 34K in 27 months - daily commute is 10 miles each way, light hauling when I do (diesel zero turn, skid steer, etc.) normally have a multi hundred mile trip (1-200 miles each way) about every month. Something that may be a factor - I don't know what is normal but going off memory here I think there are about 3000 or so engine hours with 900 or so being idle time

Can't comment on dpf problem, but with regards to change oil and check coolant messages, you have to go into the menus and reset those yourself after an oil change. I don't personally bother checking coolant unless the system has been opened up. I just reset that one every oil change and move on.

like said above, make sure it will work and is the same, even some pickups in the same model years had different sensors and plugs, etc. don't know why, but don't just buy one off anybody

I talked with a local Ford diesel mechanic who works at the one dealership I would still go too. He had the same opinion - new DPF needed, at this point I'm thinking about going for the delete
