E53 Unique Brake Issue

[Golfknar]

Well at least from what I’ve found. It’s not the bulbs, sockets, or board it seems. I’m getting 10-11 volts on the brake wires on a multimeter but the one not working doesn’t seem to be getting the signal voltage. When I check the voltage on the signal wire on the working side it shows a few hundred milliamperes when the pedal is pressed other side nothing.

Is there a reset I need to do in the computer to start sending the signal again? It seems only one will work at a single time, first was passenger now driver. I’m lost to what to check next.

Any ideas?

I’ve searched through forums for answers but only find the socket issues.
