My Audi 2009 A3 2.0 Quatro, has a consistent back left LED Light out. Traced down so far to one wire (black or drk grey) that is not bringing power to that rear LED. None of the other Light BULBS (turn signal,brake & reverse) are affected. They all work fine. So either bad or shorted wire or I think it leads to the Power Distribution Control Module (interior) also known as the Vehicle Elect System Control Unit. This is where most of the Relays are located also. A very expensive part to replace @ $360.00 +. Don't know if there is any other troubleshooting I missed but I can't justify spending that much for a tail light problem. Anybody that has had the same problem let me know, two or more heads in this maybe then I can decide what to do next.
