Have you checked the headlight range module underneath your glove box (see address 55 in your VCDS scan). Hard to imagine a coherence with your gearbox error but did someone screw around with the wires there?

On the gearbox socket (with the socket disconnected from the gearbox), the car with the ignition on, I have 2 power supplies 12.1 volts on the 1.1 volt bus, light blue with a black wire going back to the ECU (before it was diverted to the BCM). There are 2 green ones that I don't know where they go (I can't find the same color wires at EGS).

I have removed all modules without BSM BSM2 one by one. Not to interrupt due to a flooded module. When I disconnect the gearbox I think there is no problem with the can bus
