G20 NFC problem

XZBMW  G20 NFC problem
Hi.

I have a question about NFC reader in car doors. 

My car was damaged in the driver's door. The door was replaced, all door equipment is from original damaged door (wiring, mirror, handle, door panel). 
I have this error when I scan the car with ISTA:
804855 NFC reader, outside TAGE, driver's side: hardware defect

I already checked all fuses. 
Another symptom is that the ambient light on the driver door also not working. 

Is anybody stumbled upon on similar problem ?

Seems like a wiring harness issue/damage. Guessing a wire or 2 got pinched. Grab the wiring diagram and start testing the wires one by one to the connector at the door hinge area. The connector is X28*1B
