Question about 2003 BMW 330
Hi there everyone my 2002 e46 bmw clubsport has developed a fault with the drivers side xenon headlight , the light has gone out so i brought a new bulb but this did not solve the problem it would appear that there is either a electrical fault , i changed the bulbs around so know they are ok , since the drivers side stopped working the passenger side has started to flicker and flash when switched on any advise would be very gratefully received cheers scott
There are 3 things that make the xenon in your car work the bulb, an ignitor, and a control module, you know your bulbs are ok so thats good, now you will want to swap the control modules they are a metal box attached to the headlight assembly its roughly 4"x4" you will remove the hheadlight assemblys to get to the module, there are 4 8mm bolts and then it pulls out, it the light follows the control module then thats what you will need if not you will need an ignigtor, as far as the flickering that is moet likely the module going bad, the company that makes this system is AL (automotive lighting) there is an SIB from BMW about this that says under a warr claim both control modules are to be replaced and the bulb of the faulty headlight, however i cant count the number of times i have done all that and still have to replace the ignigtor, If it is the Ign that is alot harder to swap as you have to dis assembly the entire light assembly

My Drivers side had a problem where i needed to turn the head lamp on and off a number of times before it came on.
Then it went out completly, the bulbs where replaced with new ones. That didnt correct the issue.
Now my passenger side is having a similar issue.
I have purchased a part used head lamp with the ignitor and control unit intact, so need to swap these out with the broken one.
Do you have any manuals on how to remove the entire unit?
How long is the warrenty? (My car is a 1999 323ci)
