Ok here is the situation. I was trying to upgrade my D1S's to 8000k. I removed the stock one's and installed the new 8k. Now the headlights won't turn on. So I uninstalled them and put back stock. Still nothing. I checked every fuse and even tried pulling the battery. Still nothing. For the life of me I can't figure out what is going on.

Also, the left and right "low beam malfunction light" is on now. I am probably going to just have to bring this car to BMW. But I am really trying to avoid this.

Does anyone have a suggestion?

First thing first, did you plug back in the wiring harness onto the xenon bulb? Make sure that the connection is tight. Secondly, did you plug back in the main wiring harness to the headlight. Third, did you unplug any modules / ballast during the install process.

^^ I checked everything you just mentioned. This problem is very weird.

Just got back from the dealer and they have no clue what is wrong. They actually want me to bring the car back on monday. So now I have no headlights for like 4 days. Real safe...

If anyone has a suggestion please post or PM me. THANKS!!

you didint move the wires around at all did you. The bi-xenon part has a small actuator that pushes out at the very bottom of the xenon part. make sure the wires arent wrapped up in there. you should be able to pull gently on the metal actuator moving a lever right in front of the xenon bulb

you sure they are 35W H8 bulbs right?? Maybe they caused a short when installed.

I will def check... Thanks. I did take the whole thing apart again and looked it all over. Everything seems fine.

The not H8 bulbs in the e90. There DS1 size bulb. And yeh they are the exact specs there suppose to be. Trust me this is very weird. We have installed these lights in about 50 cars and nothings. Mine, and there is problem.

If it wasn't for bad luck... I'd have no luck at all.

Anyone have other suggestions? I am open for anything.

I know this post is old but I had the same problem and no one posted a solution. It could of helped me before all the costs! So here is my follow up to this problem....
This is for my situation, let me know if this was correct with yours?

"
UPDATE: So i finally figured out what was wrong.

The modification shop used some generic HIDs thus shorting out the ballas (?spelling) under the headlight. As explained to me there are two ballases, one on the end of the bulb and one under the headlight. The BMW tech called it a xenon processor.

I took it to BMW and they would not warranty the work so be careful. It ended up costing $1700 with parts and labor. Needless to say I refused to pay for it and the mod shop had to cover the cost.

Apparently this is a common problem when people use generic HIDs. At the time, I took the car into get tinted and the guy upsold me on saying the car would look awesome with some HIDs so I said ok lets do it. Not knowing anything (before I was a member of this forum ) So be careful!!

Thought I'd follow up cause I looked all over the forum for an answer to this problem and found other who had it yet no one posted the solution!"

I had the same problem with my car. Ask to check the headlight controllers (not ballasts). If they are out, then you are out of $800 or so (Tischer sells them at $330 a piece).
