Left bi-xenon headlight out.
Hello everyone. 2004 x5 3.0i. My left headlight is out and I’m having a tough time trying to pinpoint the problem. Since I’ve owned it (only a few months) I have not gone the headlight to work. I have troubleshot it the following ways:
*unhooked the battery a few times *Switched the bulbs and ballast with the right HL. The left ballast and bulb work fine in the right. * unplugged and plugged in the LCM. No luck. *I looked for the alc module behind the glove box but I didn’t see it or a wiring harness for it. So I guess I don’t have one? *looked at the wires inside the headlight but didn’t see anything concerning. At this point I’m out of ideas. Any help would be great appreciated. Thanks |

Do you have leveling and steering function optioned (S524 Adaptive Headlights)? If not, you won't have the ALC module.
Each headlight does also have a control module on it though (not the xenon ballast). I forget the nomenclature for it. But if it goes out you will lose that headlight. Had this happen to me due to water intrusion. I documented a workaround for it on the forums. I'll search it and link it below. But, the headlight modules are not expensive and do not require coding other than an initialization. I used INPA to do it as PropellerHead did. https://xoutpost.com/bmw-sav-forums/...questions.html |
@ PropellerHead and crystal works: so I have a laptop with inpa on it. I have the kcan cable too. I’m not sure which way the switch should be in though. Any chance you guys can walk me through it to initialization it? I’m very née to coding and so is my friend who owns the laptop. Thanks

Do your headlights have one of these underneath?

Yes I believe I do. Mine has a yellow label on one side. It says “5dv 008 29***” 2683010450”. Other part says it’s made in Germany by hella |
