Hi everbody! My name is Leo, a new Audi Forums member from Hong Kong, My ride is 2004 B6 A4 1.8T S-line, I love it very much....

Recently,I wanna change my headlight with a new one, and I found the following:

Valeo European Bi-Xenon Headlight Housing Kit
Xenon ready European housing for factory Bi-Xenon headlights
Complete European headlight kit. Allows for a much brighter & crisper beam along with a nice cosmetic upgrade. Charcoal housings for that stealth look. These housing for cars that have Bi-xenon Factory headlamps. Requires removal of stock HID components & bulbs from OEM headlight to be installed in Euro housing.

It looks great and better than the original one...
But according to the seller, its a Bi-Xenon headling made by Valeo for ALL type of B6 A4, but I dont know whether it can be installed for my B6 sline or not, actually, I dont understand the captioned product details....

'These housing for cars that have Bi-xenon Factory headlamps' ...but there should be no A4 comes with factory Bixenon headlamp...
What means by Euro housing??
'Requires removal of stock HID components & bulbs from OEM headlight to be installed in Euro housing'...what does it means?

 

Best of my knowledge, the S-line options are mainly suspension-related, and have no bearing on the headlights. These should fit without a problem.

 

I didn't know there was S Line in 2004...

Also A4 DID come stock w/ Bi- Zenon... If your A4 came w/ Bi- Zenon from the factory you should be able to swap them. If you had halogen headlights and want to convert to Bi- Zenon your gonna have a problem...
