I have the same problem. First I received a error message on the console for the right reverse light, then for boths reverse lights and this evening for both reverse lights and the left low beam light! What should I to identify the problem?

 

Left side, all lights having issue. ALL ***** are new, yes I utilized gloves. New stabilizer, (stock substitutions from audi), and now, not even a month into new globules, tail light doesn't work, front lamp on left doesn't work yet mist lights, brake lights and turn signals do?!? Possibly switch? Be that as it may, everything else works, not certain here. Had it at Audi and they said there is no issue, no mistake codes, I'm kinda getting baffled here.

 

My five year old Audi presented with this warning a couple of weeks ago. I called Audi Australia who said $680 to replace the headlight. I went online and purchased a Philips bulb, exactly the same and the one in the car, $100 delivered. It took two minutes to open the hood, remove the cover, quarter turn the bulb, unplug the light, then replace the bulb. If the bulb is on the right its a tiny bit more difficult but Im not a mechanic and it was just a couple of screw turns and pull the headlight out and do the same procedure. I have no experience with cars and it was that easy. I watched a Youtube video about how to do it. Simples.
