At my office we have 2 chargers per 4 parking spots, so typically if you don't get one of the 2 chargers when you park you leave your charge port door open so those who snagged the charger before you arrived can connect you to the charger if the leave/go to lunch/etc. In prep for this I parked my M3 and went ahead and inserted the J1772 adapter into my car hoping someone would plug it in. At lunch I came out and the two cars using the two chargers hadn't moved, but other spots were open. Unfortunately I could not figure out how to remove the adapter to allow it to safely close the charge port door. If it's documented somewhere I can't find it, how do you remove the adapter if you don't have a charger connected? Locking/unlocking didn't seem to do it. I'm sure I'm missing something obvious, feel free to tell me how I'm dumb .
