Audi A7 2013 sportblack
I’m facing an issue with the led lamps on the bar of the doors. Apparently, the led light door from the passenger doesn’t light up as the driver is on, in the back doors, the light is off in the back driver’s door and is on in the back of the passenger’s door. Any idea?? thanks
