I just finished installing sport seats from a lci 135i (afaik theyre the same as E92 seats) into my pre lci 330i e90, and have had some issues that I believe may either be due to coding or internal computer issues.

I've already dealt with all of the common issues like power for the lumbar and side bolsters, as well as the seatbelt mount (tapped the bracket so the seatbelt screw mounts onto the seat). The drivers seat swapped in without issues (heat, side bolsters, lumbar all work), but the passenger seat only has side bolsters and lumbar working.

The electric controls for the passenger seat only work when the harness is reconnected while battery is disconnected, and then connecting the battery. The computer driving the passenger seat's electric controls then work for ~10 seconds. It stays awake as long as I'm adjusting the controls, then power seems to shut off and the electric controls don't work. Since the electric controls work, is this a programming issue? or something related to the computer that controls the seat position?
