    Help Please! headlights (xenon)

    I really need some help trying to figure out these headlights i will try and go through everything so if anyone can understand and help me figure this out that would be great! I have an 02 325Ci and it originally had the halogen headlights but I just bought some 01 m3 headlights (xenon) and wanted to put them on, I first tried them without removing my stock ones then I just plugged in one of the new ones real quick to see if it worked and it immediately started flickering like crazy. I then found out that having faulty taillight grounds can cause these ones to start doing this so the next day i fixed the tail light ground and then re-plugged it in and it started working just fine. Now let me say that I've been trying all of this with the car off, once I had seen it worked I removed my old ones and mounted these two then turned them on and they seemed to work just fine until i start the car and then they just start flickering like crazy. So I can turn these xenon ones but with the car off and I've had them on for five minutes and they didn't flicker once and then as soon as I start the car they start going crazy and it is both of them. Please any help would be appreciated

    You need to re-program the LCM (Light Control Module) to tell it you have Xenon headlights. You can do that with NCS Expert. Plenty of guides on this forum on how to use it.
