Looking to do the Bi-Xenon conversion to my A3 is 2012 S-Line hasnt got the holes for washers but ive seen about that some of the a3s you can plug bi xenons in and then just have to code in? and do you have to have auto leveling as it seems pretty expensive for the motors and all that? I do Plan on getting the washers done though. The caris a facelift Version
