B0107 is the second lidar washer actuator. Why a car would need several becomes clear in Uber's 2016 patent: its roof lidar is washed by three separate nozzle units, each with its own pump and check valve, fed from one reservoir, and the controller normally sprays fluid first and then dries with air. A fault on one pump leaves only that segment of the window dirty. ARaymond's cleaning brochure shows multi-outlet lidar nozzles and integrated electromagnetic valves as an alternative to one pump per nozzle. Kautex supplies complete reservoir, pump and nozzle sets for camera and lidar cleaning. B0107 has no published meaning at any vehicle maker, and whether B is a second lidar or a second nozzle on the same one is not stated anywhere.

Likely causes

Washer pump B worn or its motor open
Check valve or line to nozzle B blocked, pump runs against closed path
Chafed wiring to actuator B

Symptoms

  • One section of the lidar window stays dirty after washing
  • Repeated cleaning requests and lidar degraded warning
