Q5 2009 right DRL not working

[Bartlomiej]

There is no voltage to the headlight on pin 12, the blue-red cable.
it is probably a PWM led power supply.
Does anyone know where I can find the other end of this cable?
or what could be the reason for the lack of voltage in the right lamp

edit

The lights are powered by the CECM/bcm module.
Fault codes:
02895 - Supply Voltage for LED Module for DRL and Parking Light; Left
012 - Electrical Fault in Circuit

02897 - Supply Voltage for LED Module for DRL and Parking Light; Right
012 - Electrical Fault in Circuit

left drl works fine
did anyone have a similar problem?

if I do not find another solution, I will pull the power from the left to the right but I do not know if the higher load will be good for the bcm module

greetings
