i did a clear corner mod on my b6 a4 today. i was very suprised as to how easy it was. i checked out two tutorials on how to do it; after reading them both i decided to go with the one at a4mods.com. the primary difference between the two (the other being at audiworld) was that the one on audiworld has you remove the amber plastic insert through the projecter lens hole. which requires 3 tiny pain in the *** screws to be loosened. a4mods tutorial has you remove the plastic insert by unhooking the motor for the autoleveling of the headlights, and this allows the light reflecting portion of the headlight to slide forward just enough to slip out the amber insert underneath. i highly suggest going this route,, much easier. each light took me about a half an hour and im not that much of a do it yourselfer. if you have a b6 and havent done this mod, i am hear to say it is mad easy and as we all know looks so much cleaner. so give it a try, theres pretty much no way you are going to screw it up!
