I'm trying to change a headlight bulb on my daughters 2013 X5 i35d. I looked online and found good instructions that apparently apply to pre-LCI headlights, but can't find anything about the type of mounting on hers. There are no visible retainers, but the bulb won't come out. I've tried twisting and pulling to no avail. I'm afraid to use too much force for fear of breaking something in the adaptive headlight actuator system. Has anybody ever changed one of these before?
