Hello Everyone, I just had a couple of questions about replacing the Xenon bulbs on my 2003 B6 A4. First, I was wondering if anyone could give me the model # for the correct bulb as I have been finding alot of conflicting information regarding this number. Second, what size torx driver does it require to do the job. Also I was wondering if anyone would know if the metal clasp being undone on the back of the headlight assembly would cause the bulb to go out prematurly. My LED display said I had a "dipped headlight" I do not have a manual with the car but I am assuming that it means that the bulb is no longer good. Any info that you all could give me would be most helpful. Thank you in advance to everyone!

 

I used a T-30 torx bit for my A4. The bulbs can be found at;

Thank-you so much for the help! I had another question regarding 8000K bulbs, with my stock Xenon setup can I just put these bulbs in and not have to worry. And if so where is the best place to get the 8000K's

 

They may be more purple than blue/white.
I'd keep it 4,300K, 5,000K or 6,000K.

 

Hi,
Can someone please tell me step-by-step on how to replace the xenon headlights on the A4 1.8T? Are they any DIY links for xenon headlight replacement?

Thanks!
