Hello, i need help meybe its something else before i change bcm module.

Its audi a6 c6 2012 2.7tdi xenon without led DRL

Problem:
When you turn on daylight light they will (turn on 3sec then both off them turns off) after that fault code is displayed on panel for only one side that is open circuit

i changed both of them with bosch ones, same problem.

After they turns off i cannot turn on manually by vcds test function

seems like a coding problem, is this your own car, or someone else's, i suspect someones been messing around with vcds or something else without knowing what they're doin

the wiring in the headlight most likely is bad, they all are "burned" and the isolation is falling a part.

i confirm that wires are 100% in good shape

I had a similar situation with the Audi A6 2.0 TDI 2015y.

After removing the bumper, it turned out that the wires are frayed / broken.

Please check the code

Are all bulbs standard / original in the headlight?
