It sounds like its your footwell module wince you swapped the complete headlight units and they still don't work. There is an ECU under each xenon headlight. But like I said... it sounds like it's your footwell module.
As for how to figure out when you have a bad bulb... you can press and hold the BC(Board Computer) button down and read out the error code.

Hey Dackelone
thanks again for the tips, I dropped off my car to the dealer today and the service advisor told me that if the problem is my FRM Module they will replace it but they may not be able to save my tune (Dinan stage 3) is this correct? I would think they would be able to flash to stock and flash my tune back. This is getting pretty ridiculous all for just a headlight
