Hauled 10,000 lb trailer 500 miles in 90 degree weather through three significant mountain passes. Other than a blowout on the trailer no issues whatsoever on the 10 hour drive. Set out to return with the empty trailer and on comes the CEL. Friendly small town Ford dealer scanned the code and reported what is in the title above. Took the truck into my dealer this morning and they confirmed the code. DPF needs replacing. Only trouble is there doesn't seem to be any DPF's available! Service Rep says maybe two weeks. Has anyone else seen this code? Has anyone else had to replace the DPF? 2019 F250 with just under 17,000 miles.
