B0106 code meaning
LIDAR Washer Actuator A
What B0106 means
B0106 opens a row of four lidar washer actuators (A to D). The actuator is whatever delivers fluid to a lidar window: a washer pump or an electromagnetic valve. In Ford's patent US10569746B2 a computer triggers a wash pump for the spray nozzle of a roof lidar, after an air nozzle has run for about 5 s and the window is still more than about 20 % opaque; a wiper follows only if needed. Solero builds 2/2- and 3/2-way valves that send washer fluid to individual nozzles, including lidar. AUMOVIO's lidar nozzles clean the dome with pressurised liquid using the Coanda effect. Which lidar or nozzle the maker calls A is not published, and no carmaker documents B0106. When the wash fails, the lidar may report a blocked view.

Symptoms of B0106
- No spray reaches lidar A during a cleaning cycle
- Lidar blocked message and reduced automated driving availability
Common causes of B0106
- Most likelyWasher pump or valve A for the lidar nozzle seized or electrically open
- PossibleWiring or plug fault at actuator A
- Less likelyFrozen washer fluid blocking pump A
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note B0106 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.
Questions about B0106
What does B0106 mean?
B0106 means "LIDAR Washer Actuator A". B0106 opens a row of four lidar washer actuators (A to D). It is a generic code, so it means the same on every make.
Is it safe to drive with B0106?
Drive gently and only to a workshop. With B0106 the car can go into limp mode (reduced power) to protect itself.
Will B0106 fail an emissions test?
B0106 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B0106 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
