I changed my headlights with OEM bi-xenon. It works properly after some modifications. First of all you need a jumper from pin8 to pin7.. Then you'll see xenon, direction indicators, parking lamps and high beam working. You must change levelling motor with halogens for levelling. Because you know normally bi-xenon headlight comes with automatic headlamp levelling system. So DC motor is different with halogen. That is 4 pin on socket. But 3pin on manuel levelling system DC motor. I used my halogen headlights motor and plugs. It's working at the moment. This is my old headlights.
