my situation arose because when i first swapped out to bixenons, i also removed the driver's side bracket below the headlight assembly. i tried to reposition it 2wice exactly the way it was, but can't get there. so the gap between the lower headlight body trim and the bumper is slightly more than what it is on the passenger side.
hence, the aiming on the driver's side got the projector maybe 1/8" closer to the headlight lens....
does this make sense ?
