| Description of the problem | I own a 2004 bmw 3 series sedan with optional bi-xenon headlights. About 10,000 miles into my purchase (or 57,000) i began to notice my headlight output deteriorating significantly. My girlfriend owns a 2004 bmw 3 series coupe/convertible also with the optional bi-zenon and 60,000 miles. I compared our vehicles headlights side by side. My bi-xenon headlights in both low and high beam form were significantly dimmer and had a yellow tint when compared to her bi-xenon headlights. This is a common issue on bmw 3 series sedans with the optional bi-xenon headlamps. The problem is that the bi-xenon reflector housing bowl in bmw e46 3 series sedans is made from a different manufacturer than the coupes and convertibles. The headlights in my vehicle are made and classified under the title (zkw). The coupes and convertibles are made and classified under the name (al). The difference is that oem zkw headlights reflector housing bowls are made from a type of plastic. While the oem al headlights are made out of metal. The metal housing in al style headlights in coupes and convertibles are able to stand up to the heat of the xenon bulb, the plastic housings in my sedan are not. Due to this it literally gets too hot and burns the plastic reflective housing to a brown crisp, which is not a reflective surface and deteriorated my headlight output to an extremely unsafe level. The output level has dimmed so that when there is any oncoming traffic my lights get drowned out and i must put on my fog lamps to maintain any type of visibility. The output level is below any halogen lamp i have seen. This is extremely unsafe at any speed and is a known issue on all bi-xenon equipped bmw e46 3 series sedans. Bmw is aware of this issue and has done nothing to address this design flaw, which compromises the safety of myself and others. Pictures of the issue are available upon request. Thank you. |
