What Causes the Volkswagen Radar Malfunction Warning?
1 Answers
Check if the wiring connections are loose. Below are the specific details about the malfunction warning: 1. Sensor Issues: The problem might lie with the sensor itself or the radar control box. If a malfunction occurs, try replacing the control box with a new one. 2. Obstruction Presence: In certain special circumstances, due to weather or car washing, a layer of accumulated water and dust can form between the parking sensor and the bumper hole. This layer can create a channel for ultrasonic wave transmission between the sensor and the bumper. The ultrasonic signals emitted by the sensor may pass through this layer to the bumper and then reflect back to the sensor, causing some vehicles' sensors to mistakenly detect an obstacle nearby, leading to false alarms. 3. Solution: Regular cleaning of the parking sensors can eliminate the malfunction.
