B0107 code meaning
LIDAR Washer Actuator B
What B0107 means
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.

What to do next
- Note B0107 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
