xenon light issues
2004 X5 4.4i
Are there common issues that are known with the xenon lights on the X5? I was getting control light errors on the dash and have since replace the bulbs and the ballast for both lights. The right light would come on every now an then but the left does't come on. No longer getting the error on the dash but still not coming on. Good thing it make the fog lights come on by default when they are not working. I have not gotten a chance to scan for codes. Are there any common issues that others have come across? The wires all look fine. :dunno: Thanks |

Maybe problem with the wiring within the headlight unit ??

Swapping parts to see if the problem moves is an excellent suggestion. Take your VOM and see where you do (and do not) have power. Did you also check fuses / relays?

When the wife comes back in I will fire up the BMW software and see if any codes popup. Hope its not the control module going/gone. |

In the pic below of the left side...you remove the 4 screws that hold the plastic cover: Which then exposes the ignitor (#2 in pic below): Also, still assuming you have the adaptive bi-xenons...if the bulbs & ignitor turn out NOT to be the issue...you any want to do a search for the ALC control unit. When it goes on the fritz it can cause illumination issues. |
OK so the ignitor is what I was calling the ballast..sorry about that. I had gotten 2 new ones and swap them out and the issue was the same. The bulbs are new. I got the scan done and nothing showed up that would indicate lighting issues. Didn't think I would see anything since I am not getting any error alert on the dashboard. Next will to find this ALC unit and see what happen.
