This is what the service reciept says:
Carry out work as per campaign bulletin
MIR9481A092 Charger, EV battery Kit
10MY 1-Miev ON BOARD CHARGER/DC-DC CONVERTER Misc :RND 1 & 2 c rounding 0.02
Actually the reciept doesn't make much sense to me, I've attached a photo of it.
I think this is something that came up on their system when we brought it in for the ECU, rust on battery frame, vacuum pump, recalls that we were notified about, we had no notification for this one.
I can't find anything about that recall online, and if I enter my VIN into the official mitsubishi page to search for recalls it just says invalid VIN.
