Bi xenon help!

[bagpype]

My 2006 X5 has bi xenons. The light switch is always flashing green. Ive noticed that the drivers side headlight adjusts up and down when i start the car but the passenger side stays sedentary. How do i pinpoint what the problem might be? Ive read through so many threads to no avail. Any help will be very appreciated.

I'm not sure if there is a specific connection for the the 'motors' in the housing or not....but as always, check the connections.

If you have time, I think (again, I think) you can swap the units to see if it's a wiring or housing issue. Obviously you have to pull the housing/lamps out....and hope the harnesses are long enough.

Finally, I think the dealer can control the functions of the lamps/motors with their devices.....it might cost you $100...but would be the fastest way to figure it out.

After writing this, I'd go with option 3 after doing a quick inspection of the connections.

do you own any diagnostic tools, like an OBD cable, GT1, or INPA software? the flashing green light is on the light switch, right?

If I recall the leveling motors have a 4 pin connector. You have to remove the torx screws on back cover of the headlamp housing to gain access. You can also swap them from left to right to test them out... as they are the same for each side. It would really be much easier to grab a hold of the proper diagnostic equipment and save yourself the hassle though...

I don't have a diagnostic tool for BMW but it wouldn't be a bad idea for me to get one. Where is a good source for the cable and program?

[TerminatorX5]

ebay, do a search for INPA (software) along with a cable

Will this work? Loftek Interface USB OBD2 OBD II for BMW - INPA/ Ediabas - K+ DCAN:Amazon:Automotive

Just for the record...the green light next to the light switch...when "flashing" means that adaptive headlamp control has registered a fault, right? Does it also "flash" if the leveling sensor goes on the fritz, too?

Blinking indicates a fault with the adaptive headlight. It should be constant green when it's on.

Yes I agree on steady means active
