There is no lumbar in the CF buckets retrofit that I did, so only 3 wires were required to match the A246 scheme from the OEM switch, and no position sensor error.
You may need to consult your particular controller schematic in here in case of wires missing from mine : https://bmwtechinfo.bmwgroup.com/#/login
Regardless, try manually setting the seat position sensor first: car off, move seat all the way forward until stops, press button again until stops again, then move seat all the way back until stop, then press button again until stops again. This should reset the position sensor.

Okay,
I have found all the diagrams via ISTA and now what you said made sense. The module isn't actually powered without the pin 7 connection and that wasn't clear until I looked at the diagrams.
Pin7 yellow connector is lights.
Pin7 A246*3B needs supply.
The fact that there are two Pin7 references is what had me confused.
Did you have to make any manual connection besides the two can connections and power? Was the LIN bus connected correctly?
I presume, it will stop looking for LIN stuff once the controller is powered correctly.
I figure I'll wire the lights since I have to be in there one more time.
I'm done with questions now that I have ISTA and all the diagrams.
Thanks!
