So, here as a separate thread, in the hope that someone can help me further. Since I have placed a used BCM (1S0 937 087 K) in my Seat Mii, this BCM provides wrong errors over the flashing lights at the rear (left + right). If I delete the errors, they come back immediately. The lights themselves work perfectly. The errors themselves would not disturb me, but the flashing LEDs in the instrument cluster + the acoustic signal run twice as fast as normal. That’s annoying already a bit I guess it has something to do with the coding. I have transferred the coding of the old BCM (1S0 937 086 F) as well as possible, but maybe something doesn’t fit anyway. Maybe someone knows this here. Can this possibly be at the value for byte 18? The value 40 is not recognized by VCDS… If someone accidentally installed the same BCM, and sometimes because the coding could be read out, I would be very grateful! Photos of the error codes and the coding for the old BCM!
