Recently had the drivers side headlight replaced under warranty (moisture + dead LED accent) and the aiming seems off pointed high and to the center of car compared to before. Took it back to the dealer and they adjusted the vertical axis but said there is no adjustment for the horizontal axis. I know there is a channel in the headlight housing for adjustment horizontally (aimed outward beside the channel to the vertical adjustment screw) but at the end there is a smooth white cap that cant be removed. Looked everywhere online for the "Headlight Aiming" section referenced in the '17+ Service/Workshop manual but cannot find it. Any help is appreciated!
