How to Solve Mercedes-Benz Protection System Malfunction?

Focus on checking the fuel pressure and whether there are leaks or blockages in the intake system. Inspect if the sensor measuring the intake air volume in the intake system is damaged. Possible reasons include poor fuel quality.

I've been driving a Mercedes for several years, and a malfunction in the protection system is no small matter. I remember last time, the dashboard suddenly flashed a warning light, indicating that the pre-safe system had failed, which made me quite nervous. First, I checked myself: made sure all doors were properly closed, and that no heavy items in the trunk were blocking the sensors; tried turning off the engine and waiting ten minutes before restarting—sometimes this can temporarily fix minor software issues. But that time, restarting didn’t help, so I had to drive to the Mercedes 4S shop. They connected the diagnostic computer and found that the front radar sensor was covered in mud. After cleaning it, everything returned to normal. I think if you encounter this kind of situation, don’t wait—pull over immediately and call to schedule professional service. Usually, when washing the car, take a moment to clean the sensor area to avoid dust buildup causing false alarms. Safety is something you can never take lightly.
