Why Did the Mercedes-Benz Reversing System Stop Working?
4 Answers
Mercedes-Benz reversing system stopping operation is due to a malfunction in the reversing radar, and a restart should resolve the issue. Taking the Mercedes-Benz A-Class 2020 Facelift A180L as an example: it is a compact 4-door, 5-seat sedan with dimensions of 4622mm in length, 1796mm in width, and 1454mm in height, and a wheelbase of 2789mm. It is equipped with a 7-speed dual-clutch transmission, reaching a top speed of 218 kilometers per hour. The Mercedes-Benz A-Class 2020 Facelift A180L uses a 1.3T inline 4-cylinder engine with a maximum power output of 100 kilowatts and a maximum torque of 200 Newton-meters. The front suspension uses a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension.
I've been driving a Mercedes for several years and often encounter issues with the reverse parking system, most of which are caused by minor problems. For example, the radar sensors on the rear bumper might be covered with mud or dust—just wiping them with a soft cloth usually fixes it. Another possibility is that the sensor wiring gets loose on bumpy roads; simply checking and securing the connectors near the trunk can solve the problem. Software glitches are also common. Like that one time after a system update, the system stopped working, but it came back to normal after restarting the car and waiting a few minutes. If none of these solutions work, don't push your luck—head to the dealership immediately, as driving without parking assistance increases the risk of scratches or accidents. Also, sensors are prone to fogging up in cold weather, so it's good practice to maintain them during car washes. In short, don’t overlook simple checks—safety first and it saves money too.
Last time, the reverse radar on my Mercedes suddenly failed, which really scared me. Upon inspection, I found the camera was blocked by insect remains—washing it off with clean water fixed the issue. If cleaning doesn’t help, there might be an electrical problem, like a blown fuse or aged/cracked wiring. I learned to locate the fuse position in the user manual for self-checking. Software glitches can cause false alarms; try disconnecting and reconnecting the battery. Remember, never force reverse, especially in crowded areas—relying on mirrors is less efficient. I recommend regularly cleaning sensors to avoid surprises. Persistent issues warrant a professional inspection to identify the root cause, as delays could lead to greater risks.
When my Mercedes reversing system malfunctions, I first check if the sensor lens is dirty and try wiping it. If that doesn't work, inspect the fuse box to see if the relevant fuse has blown and replace it. Resetting the electronic equipment is also effective: turn off the car, wait a few minutes, and then restart. If none of these steps work, it might be due to wiring damage or module failure—don't delay and seek a technician for diagnosis. Safety comes first when driving; be extremely cautious when assistance systems fail.
