Xenons flickering...HELP!

Hello everyone, I have a 2001 330i and recently my xenons have been flickering. Both sides will go off and instantly back on. The 01's have xenons for low beams only. I do have a Dinan CAI and they've relocated the xenon module on the left side of the car. Also I have the first generation halos installed which means that they've spliced off some wire for power. I'm not very technical at all so if anyone can provide me with some insight, I would greatly appreciate it. Or maybe if anyone else in this community has had this problem, please let me know how I can fix it.

Thanks everyone

I had the same problem and it ended up being a bad Xenon ballast. I was still under warranty at the time, but I think a replacement is about $400 or $500.

I just had mine in for service, BMW has isssued a service bulletin for bad "igniters", its the module that turns them on and off like D3 said.

first thing to do for a fix is replacing the bulb. if that doesn't solve the problem, it would be either the igniter or ballast. i had the same problem once, had an extra set of bixenons laying around, so i gutted out the ballast and replaced the one on my headlight with it. worked fine after.

the igniter and ballast are two different things. The ballast is the power source for the high intesity discharge lights. It could be anyone of the three. like he said above, if you can get your hands on a pair or even just A bulb to swap out and test go for it and see if its the problem. If the problem is a ballast or igniter just get one from JLevi, its a helluva lot cheaper

I had the same problem except the left turn signal was blinking like a machine gun. I reseated the turn signal bulb and everything went back to normal. The research I had done on this site leads me to think that the LCM was resetting itself, hence the flickering.

No need to replace the bulbs, it's the igniters. I had this problem. If you don't replace the igniters it will burn out your bulbs which are 160 bucks a piece.

I'm not sure in which forum, but there was a post about this before. For me xenons started flickering a few months ago and it became even more in colder weather. Some people said ballasts, bulbs, it turned out to be none of them in my situation. First check if you have showing "lights out" on your dash. For me sometimes it would show, but then disappear without real pattern, showing one of the turn signal bulbs in the rear. Checked bulbs, were perfectly fine in front and rear. Checked rear and front bulb housings it was fine too. It turned out to be the connection between rear bulb housing and the car(if you disconnect it you can remove rear bulb housing). Once I disconnected I saw that it was kind of blueish color (kind of like on battery sometimes). So I cleaned the connections, put some electrical grease and flickering is gone. And the cost is FREE

flickering

Litxus,
I had the same symptoms with the car detecting the rear light going out. The car's warning light came on a couple of times telling me that the driver's side rear light was out. Then after a couple of starts later, it went away. I thought it was weird. I've seen the front bulb contacts get worn out but I don't know why it would be worn. I will check all the light bulbs around the car and see if anything works. It does flicker more in the cold. Weird! It hasn't flickered the last few days but its done this about a few months ago and started again a week ago. I was suspecting that the angel eye connection was causing it but hopefully it's just the bulb connections.

Thanks everyone for your input and I will definitely check everything and make sure its ok.

My rear left turn signal wires got fried and caused this to happen.

I would pull the rear lights and check the wires to make sure they aren't burnt out. I had to replace the rear cover and wires on mine. Apparently there was a attempt by NHSTA to do a recall on 1999-2002 cars because the signals can short out.

The poster has some short in the system causing the Xenons to go haywire. Actually oddly enough I found the posting:

Thanks everyone
yes i just ran in to the same issue but i fixed already!!
my xenon were blinking now and then i also noticed that when i turned on my car for the first time in the day i drove away to got to work, once i stoped at the signal light and i turned on my right signal light i noticed it'll blink too fast for 2 to 3 times like if a light bulb was out so i noticed something was going on so at night i turned on my car and checked my tail lights for bad bulbs or the brightness also, i noticed the right side wasn't as bright as the right so then i knew something was up on that side, last year i had some work done on my bumber and they removed the tail light and forgot to put the gasket back in place and water went in and wet the plug from the lights so i new it had to be corroded so i took it a part and yes that plug had some corrition on it which causes the resistance to change in the lighting system causing the xenons to fliker.
how did i fix it?
well i just remover the lights holder,removed the plug from the holder and cleaned with contact cleaner i also used a small file to scrape the metal contacts, on the car side plug i got the cap from the spray and fill it up with contact cleaner and left it over night soaking ,in the morning i removed it from the cleaner and used a hair clip to scrape it a little then i spray more cleaner then i conected it to see if the lights would start acting-up again and nothing lights are back to normal!!

good luck hope to help!!

check youre signal lights when you turn it on and see if there is anything abnormal that'll tell you which side has the fault~~!
