i3 LIM region coding

You found a BMW i3 LIM. People on ZombieVerter use these for CCS on a conversion, so it feels like the grown-up move. You bolt it up. You take it to a CCS1 station in North America. The station looks at you and does nothing useful. The inlet is fine. The gun is fine. You start suspecting the car, the adapter, your wiring, your life.

The handshake does not live in the plastic. It lives in the LIM, and the LIM is region-coded. CCS1 here wants a module that came out of a North American car. CCS2 wants one that came out of a European car. One builder bought a European i3 LIM, watched CCS1 fail, and only got a session after they swapped in the same kind of unit from an NA car. That is a miserable afternoon, and it is also the whole lesson.

ZombieVerter builders on that thread have reported two part numbers that worked for them: 9454319 and 9494498. A 2019 LIM, 6135 9470199, labeled LIM_AC_DCO, got asked about. Nobody on the thread confirmed it. Do not treat that one as interchangeable until someone actually benches it.

This page does not invent other i3 LIM part numbers. If a listing does not say which continent the car lived on, you are gambling a weekend on a module that will sit at the station and stare at you.
