What is the reason why the Volkswagen Polo reading light cannot be turned off?
2 Answers
Volkswagen Polo reading light cannot be turned off due to circuit failure. Reading Light: The reading light provides sufficient brightness for passengers when the interior lighting is insufficient, facilitating reading inside the vehicle without affecting the driver's normal operation. It is connected to the cigarette lighter socket, and upon pressing the switch, it emits lights of different colors. Currently, there are ordinary reading lights and LED reading lights in vehicles. Function of Car Reading Light: The door indicator is usually located on the reading light, which is the activation mode of the reading light. When the door is opened, the dome light turns on. If the door is opened or not closed tightly, it will also light up, serving as a warning.
I own a Volkswagen Polo and have also encountered the issue of the interior light not turning off, which seems quite common. Usually, it's because the door sensor switch is faulty or stuck, causing the light to stay on if the door isn't properly closed. Alternatively, the light switch itself might be worn out or damaged, with the contacts sticking together and failing to disconnect. Another possibility is a short circuit in the wiring, where frayed wires come into contact with the metal frame, completing the circuit and preventing the light from turning off. This problem not only drains the battery quickly—potentially leaving the car unable to start the next morning—but also poses a significant safety risk. It's best to first check if the door is fully closed and try opening and closing it a few times to see if the light turns off. As a temporary fix, I unscrewed the bulb to get by, then immediately took the car to a 4S shop or a reliable repair shop to replace the switch or fix the wiring. Never delay addressing this issue.
