The TSB 11-12-3 indicates a possible internal leak of the reductant pump and provides diagnostic direction.

Ford Motor Company TSB-11-12-3 said:
Some F-Super Duty vehicles equipped with a 6.7L diesel engine and built on or before 8/3/2011 may exhibit a malfunction indicator lamp (MIL) with DTCs P20E8 and P202D. These codes are set by a small diesel exhaust fluid (DEF) leak internal to the reductant pump assembly.
Technical service bulletins do not affect warranty coverage. MOST emissions components on your truck are covered by a 5-year/50,000 mile emissions warranty. At 57,500 miles you have passed the limitations of the warranty coverage.

Who can't find the bulletin, you or the dealer?
