HID Headlight - Adaptive Headlight Questions

[magnum1]

Hello

Have a 2004 X5 3.0 with Xenon Head lights and Adaptive headlights.
Turned on the Head lights tonight to the Automatic headlight position and the Green LED light was blinking/flashes, and my left low beam head lamp was not on.
I do not have any head light warning or lamp out warning lights on.

I think that my battery is getting to the end of its life as it sounds like it hesitates starting for a second and not starting like normal and my battery warming light flickers for a second then goes right out. This happens after it sits for about a day or so. most days I drive it 36-40 miles each way to work and it been starting fine.

Any ideas? Is the blinking green lights on the Automatic headlight control blinking because the HID lamp is out or could the weaken battery have something to do with the whole mess?
I purchased the X5 as a CPO 3 years ago and I think that it may be the orignal battery?

Any Help would be great

Happy Thanksgiving too all

Thank you
Jim

Do a search on this board. There are a number of posts. It could as simple as bulb replacement ~$400 at the dealer or ~$30-50 and 30-60 minutes DIY. It could be water damage and electronic modules -- >$2000 at the dealer and ~$500 DIY.

It seems that the lamp now works today in the normal head light on positon

Didn't try it in the Automatic position. will do that tomorrow

Thank you , at least the lamp is still good.

It is still could be and of the life for bulb, ballast and/or igniter.
I would investigate this ASAP (from my experience where water damage in the headlight unit “propagated” over weeks to other modules and indications of problem did change).
First step is to swap bulb, igniter, ballast and headlight control modules from left to right (using DIY for front bumper)…
Inspect all the modules connectors for water damage and wires inside headlight for the wires condition.
Computer will be needed to go further. Diller will test with the computer and most likely will suggest head light unit with new modules, LCM and some others replacement … VERY expensive.

One poster recently replaced his LCM which was causing an excessive battery drain, which, if bad, might give you the flashing lights.
