Official summary
Some 2017 f-super duty, 2016-2017 f650/750 vehicles built on or before 20-dec-2016 and equipped with a 6.7l engine may exhibit an illuminated mil with diagnostic trouble code (dtc) p20e8 in the powertrain control module (pcm) memory. This may be due to air trapped in the reductant lines causing the reductant pump and heater assembly to not build sufficient system pressure or loose reductant line connections. Follow the service procedure steps to correct the condition.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
