HID install problem

I just installed some hid's into my low beams. They lit up alright the first night. But now they don't work. On the gauge cluster, there is a car with headlight picture showing that they aren't working. I've searched and found something about pulling fuse 32. Is this what I need to do to make them work? What does fuse 32 do? Also is the fuse box screwed down by torx screws? TIA

I'm new to the e46 so I'm not sure. Please don't tell me this since I just spent all this money on getting hid's.

So if the HID's do not light up at ALL anymore, you will need a supplementary power harness.

Pulling Fuse 32 will NOT help you. People pull Fuse 32 when their HID's work, but they are receiving a bulb out warning when their HID's are off.

Contact Khoa @ Khoalty via PM or AIM and let him know of your situation, and that I mentioned that you will possibly need a supplementary power harness.

I read something about them. Don't know much about them though. I have a 05 330ci, which I don't know if I need p46's.

Did your car come with Xenon's from factory? Or did you install aftermarket lighting?

judging from his my rides section, he has a facelifted coupe like mines. they already come with projectors even if he has halogens.

jon, what you need to do is get your car reflashed by the dealer so that they car can recognize the xenons. that should solved the problem. or you can use the capacitor mod or try resistors.

If his car won't even fire the xenons's anymore, its not that the car is not recognizing xenons, its that there is not enough power supplied. I don't believe a reflash will fix this.

I just finished an install for a local kid who had the same problem as described. His car would not fire the xenons. Turned out he has a car that requires ANOTHER harness to fire xenons. The harness basically just connects from the battery terminals in the engine bay, out to the headlights. After installing that, it did the trick and the xenons would light up properly. I believe his car still has bulb-out warnings, which he will need separate resistors for, OR get a reflash (resistors are the cheaper way out)

How much does the reflashed cost? Is there anyway that I can do it myself? What is the capacitor mod or resistor mod? What does pulling fuse 32 help with?

A reflash will be in excess of $100.

In post #5, I told you what pulling Fuse 32 will do.

Resistor mod will only be useful to you AFTER the fact you get your lights to work.

can you do us a favor, put your key in and turn it to the position before you start the car (i think that's 2, i forgot). then turn on your headlights with the HID kit connected. does it turn on?

for facelifted coupes and a lot of the new bmws. when installing an HID kit, the lights will not come on because of the bulb out warnings. other symptoms include flickering on then off and others as you already know.

Thanks. When I go to the dealer, what do I say to them. "I want a reflash"? And this is after I get the harness?

The first night that I did it, I didn't turn on the car, just turned the key to 2nd and the lights worked every time. The next day after turning on the car, the lights don't work anymore. I turn the lights on (key in 2nd and key with car on) and the lights flicker then stay off.

ok, then we know for sure your car has enough power to turn on the xenons. you just need to get your car reflashed. might want to call your dealer first. a lot of dealers won't know what you're talking about so yea. tell them that you need you lsz (new name for lcm) reflashed to accept xenons. you may lose your high beams though.
