F30 - Problem coding an FLE for headlight retrofit (UNKN id, programming abort?)

[chambo622]

For anyone who stumbles across this in the future, the solution was to just buy a new FLE. Worked on the first try after I swapped it out. If you have an ECU that shows "programming aborted" state in ISTA with UNKN HWEL in E-Sys, it's not easy to recover - there may be some way with Tool32 or WinFKP but nothing I could reasonably figure out. Save the trouble and replace it.
