Hi guys, i've managed to get hold of some bi-xenon headlamps for my a3. They have not got the ballasts & bulbs, however im keeping an eye on uk/euro ebay for them. What I wanted to know is how the projector actually attaches to the motor as one of the lights seems to keep getting loose from the motor. It slips into the motor ok but releases itself quite easily where as the other stays put. Is there another point that it attches to something that makes it more secure? With the help of mattandrew & frenchy i've figured they are not adaptive as they only have 1 motor in each unit. Pics attached:
