1 Answers
Here are the specific reasons why the left and right brake lights of the new Audi Q5L may not be working: Reasons for brake lights not working: Brake light filament burned out, bulb damaged; Brake light switch malfunction, unable to control the brake lights; Poor grounding of the brake light. Inspection methods: First, remove the brake light bulb to check if the filament is burned out; If the bulb is intact, press the brake pedal and measure whether there is power at the live wire terminal of the brake light bulb. If there is power, it indicates poor grounding of the brake light; If there is no power, check the brake light switch and wiring. Short-circuit the brake light switch terminals. If the brake light turns on, it means the brake light switch is faulty and should be replaced; If it does not turn on, it indicates an open circuit in the wiring, and the break point should be located and repaired.
