I need some help please with my just out of warranty 15 Macan S. The right rear brake light is not working. However, all the right rear leds work fine during other functions, i.e. blinker, key fob lock/unlock. I checked all the fuses with a multimeter and all are ok. Checked for loose wires and clips....none. Also, no warning message at all on the dash. Any ideas on what's going on would be greatly appreciated.
