Hi guys, I'm trying to retrofit my G31 pre LCI with AHL pre LCI (SA552) using used parts. When I connect the new headlights, CAFD reads FFFFFFFF.255.255.255 and I can't code it. In another thread someone answered to another one with a likely similar problem that he has to flash FLM. Is that what I have to do, too? Please, no guesses, answer only if you know.

Edit: yes, flashing new FLM was the solution.
