I have the strangest thing going on with the LED tail lights in my 2011 X3. Hoping somebody might be able to help me out. It is out of warranty (65k miles). The only tail light (led) that is working is the right fender light. The 2 tail gate led lights and the far left are not working. Well, let me rephrase that.... Not working all the time. After the car sits for a while and then when started the left will work for about a minute and then dim out. All while the Right stays on continuously. Also the Right tail gate light will do the same from time to time (on for about a minute, then dims out). Took it to a local import shop and they couldn't figure it out. They recommended I replace the Left fender light for the tune of $280. But then they couldn't explain why it would work intermittently. Anybody have any ideas why this would happen? Could it be possible that a dying battery could cause this?? Anybody know how this lighting system works? Does it go to a central hub of some sort? Any thoughts or testing idea's would be awesome. Thanks!
