INPA update for N53

31amk31 · 11-17-2025, 03:38 AM

Thought to ask it in the UK section because the US guys didn't get the N53.

I have INPA but it doesn't work presumably because I don't have the correct version which includes the N53.

ISTA+ does work and NCSExpert too but INPA doesn't. I don't see the N53 in the list of engines so yeah.

Can anyone point me to a way I can get the correct INPA version that includes N53 stuff?

the inpa is leaked software, it is officially only for bmw factory employees, to fix car during production phase.
so you should chose N54 MSD80 menu entry to get to N53 ecu, they are similar
