This used OEM BMW headlight leveling sensor (part number 6855668) came from a donor i3 or i3s. It mounts on the left rear to monitor ride height and automatically adjust headlight aim as the vehicle loads or unloads. Also called the headlight aim or level sensor, its failure can cause misaligned headlights—pointing too high or too low—or trigger a dash warning. This sensor fits both the BEV and range-extender i3 variants.
