Can you take a picture of the front whith the lights on so I can see what type of headlight assembly you have? I am looking at my wiring diagram and see you do have bi-xenon? The bi-xenon circuit is on pin #5 and see pin #5 on your connector is present? So pin#3 would be your low beam. Now there looks like there is an option for daytime running lights so during the day that light comes on and at night it should switch over to bi-exenon? For now check fuse #20 in the engine compartment. When the light stops woring, with a test light verify that you have power going through on both sides of the fuse. If you do, remove the verify and visually inspect it. If it is burnt just a little it can be causing an open circuit as soon as it gets hot but just barely making contact that the test light may pick up as being ok. If that is ok, remove the sound proof panel under the dash on the drivers side and check fuse #23 as well. Also while under there, check above and you will see the central electronic module. Make sure there is no sighns of water intrusion or water marks around or near the connections. If you do then that can cause evem more problems? Let me know what you find and post the picture of the right side headlight assembly with the lights on and a picture of the left side to have something to compare please.
