Where is the Mercedes-Benz sensor located?
2 Answers
Mercedes-Benz sensors are located on the bumper. Sensors: Sensors are mainly used for forward collision prevention, side collision prevention, rear collision prevention, automatic cruise control, auto start-stop, blind spot monitoring, pedestrian detection, and autonomous driving; radar sensors reliably detect any objects within their detection beam range. Daily precautions: When the radar has no sound or other malfunctions, you can perform a self-check. When shifting into reverse gear, the controller will release an electrical signal within about one second, and it will determine whether the sensor is normal based on the residual vibration signal returned by the probe. If there is just a simple "beep" sound, it indicates normal operation. If there are two or three beeps, it indicates a sensor malfunction.
Mercedes-Benz sensors are actually quite widely distributed, with no fixed location—it depends on the type of sensor. For example, ABS sensors are usually near the wheels to detect wheel speed; when you park, the area around the wheel hubs is where they're located. There are also many in the engine bay, like the oxygen sensor near the exhaust pipe and the air flow sensor by the intake system. Around the body, parking assist sensors are often embedded in the front and rear bumpers, while inside the cabin, light and temperature sensors might be near the dashboard. After driving Mercedes for so many years, I’ve noticed sensor locations vary by model, especially in high-end versions like the S-Class, where more sensors are placed around the grille or chassis. During regular maintenance, check these areas to avoid dust buildup or damage, which could affect driving safety and trigger warning lights. If unsure, consulting the owner’s manual or visiting a professional shop is the most reliable approach.
