Hey guys, I need a working headlight ballast for HIDs or whole passanger side assembly for the headlight if possible.

Unless anybody knows which ballasts out of other models will be compatible to replace the OEM in there. Thanks!

 

Your price on a new one is 375.75 and in stock. The part number is 8E0-907-391-A and can be found on any/all 99-02 A4 and S4 wagon or sedan with xenon lights. I hope this helps you out, Jeff.
