Repairing a fallen reversing radar dot costs around 3000. Here are the details: Monitoring radar: When you find the reversing radar is not working, first check if the wiring connection at the bumper is intact, then check if the reversing light turns on when shifting to reverse gear. If it doesn't, check if the reversing light connection switch is broken. Then you can check if the computer displays any fault codes. If none of these are issues, proceed to check if the reversing radar itself is malfunctioning. How reversing radar works: During reversing, the reversing radar uses ultrasonic principles. The sensor mounted on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle and the obstacle, and then alerts the driver, making parking or reversing easier and safer.
Last time when the little dot of my car's reversing radar fell inside, it really freaked me out. I rushed to the repair shop only to find out it wasn't a big deal. The mechanic said the sensor had just detached and fallen into the gap between the rear bumper layers, and they needed to remove the bumper to retrieve and reattach it. The cost mainly consisted of three parts: labor for removal and installation (150-300 RMB), the sensor mounting bracket (a few dozen RMB), and if the sensor was damaged, a replacement would cost 50-200 RMB. Luckily for me, my car's sensor was fine, and the total cost was just 200 RMB. Here's a fun fact: you can actually check the radar sensor positions yourself by gently pressing each dot with your finger—the loose one is the problematic one.
