HELP! - AL HID low beam doesnt wanna work

ground is brown. just find any chassis point to ground it. if you want, use a long wire and go to the OEM ground.

If you look at the pic I posted you can see the brown wire on the DRL plug, it's the same color on the HID

So just splice both ends of that ground and splice a separate wire and connect them and run them to the chassis??

Sent from my DROIDX using Bimmer App

no, just splice once on the ground wire as close to the connector as possible. then the other end of the wire put it on a chassis point and test. you're going to need to do this method each time when you test something.

honestly, i would used alligator clip wires with a needle (for the connector end) so you don't have to hack up the wires trying to test.

everything lights up...

So what should i do next..

please help...

if everything lights up, then you probably have a ground/short as well. if it doesn't, then there is something wrong with the headlight itself. either the bulbs/ballast/ignitor or a combination of them.

I got every thing light up ...

Anyone could help please...

what do you mean exactly? sounds like you need to run a new ground also, just read the last ~10 posts

this is the plug/brown wire we're talking about

Hermes, did you end up fixing your car?

I haven't got around to it yet.. Luckily I have a back up car

All right guys.
I try the ground thing many times and still cannot get it work. (I try run a new ground and also making sure is not the connector's problem)
so i believe is not the grounding issue.
But my issue is almost the same as Hermes except my fog lights would turn on itself as my HID on when I set the switch to Auto.
What I do is splice the positive wire from one side to the other.
Hopefully that won't break my LCM.
So far I have put about 130 miles after that and still working fine.
Thanks for helping guys.

where have you tried it? remember the low beam connector is just a starting point. the bad ground can be any ground on your car. it just so happens that mines turned out to be the low beam, and that is after 3 days of searching. and i already checked the low beam first, just don't know why it didn't work the first time.

also, if you have HID fogs, i would check to see if maybe the ballasts on those themselves maybe shorting out and causing your issue. i've come across this as a problem once before as well.

UPDATE: so apparently disconnecting the battery for >5 minutes will clear this up. Mine work perfect now

so basically it was the ground on your battery? lol

Hermes you are the man!!!!!!!!!!!!!!!!!!!!!!

Just got mine fixed.

bringing back an old thread- My driver headlight wont work- tried the "home lighting" feature - got nothing ive tried bulbs-ignitors- so now i guess the ballast is next?

Bulbs, ignitor, ballast, LCM, full headlight housing... honestly if you have the AL's I would try unplugging the battery first. I'm kinda mad at myself for not doing that earlier in my diagnosis period

I want to share my experience with the drivers side headlight going out after hitting a small bump in the road. I tried swapping the bulb the problem was still there, and then I thought the igniter was bad because it did not spark when it was turned on with no bulb bulb place?? I then looked for a used igniter and bought one from e bay (silly me). It was after discussing it with a friend of mine I did further research here and found this thread. I already had the headlight out and decided to try and find the ground location, it is located just behind the headlight assembly. The ground is secured with a 10mm nut with several other wires (brown ones). I then removed the nut and cleaned the area with a wire brush and then flipped it 180 degrees and re attaching it. I then proceeded to re install the headlight to test. Without the key on I tried the "high beam" switch and it came on (yea), then I turned the key to the run position and turned on the lights and it came on, I'm so happy now. Anybody wanna buy a used igniter??? Thanks again guys for the help in diagnosing my headlight issue !!!!

it doesn't have to be AL's. it can be for any headlight. like i said, if both headlights work normally and that low just doesn't come on when you try it normally. it's going to be a bad ground somewhere. it's just hard to find the bad ground.
