What are the reasons for the Mercedes-Benz C200 protection system malfunction?
2 Answers
Mercedes-Benz protection system malfunction causes and solutions are as follows: Fault reasons: Damaged airbag, damaged seat belt sensor, damaged airbag sensor, anti-towing issues, etc. Fault solutions: The owner can try turning off the anti-towing function. If the anti-towing issue persists, it is necessary to visit an authorized Mercedes-Benz 4S dealership for inspection and repair. Mercedes-Benz's PRE-SAFE is a predictive safety system, also known as a pre-safe protection system. It provides the vehicle with reactive capabilities, much like a living organism, making certain self-protection adjustments when detecting danger, thereby avoiding or reducing the degree of harm.
I've been driving a Mercedes-Benz for over ten years and have encountered quite a few protection system failures. The protection system of the Mercedes-Benz C200 includes airbags, seatbelt pretensioners, and a safety assistance module, with faults typically arising from various causes. The most common issues are sensor failures, such as loose collision sensors or dust-covered sensors triggering false alarms; wiring aging and short circuits, especially under the car or in the engine bay, where moisture or corrosion can lead to unstable current flow; and software bugs, where system self-checks fail and require firmware updates. Additionally, low battery voltage, blown fuses, or module damage can also trigger faults. Whenever a warning light comes on, don't force the car to run—stop in a safe place and try restarting. If that doesn't work, I strongly recommend visiting a 4S shop for professional scanner diagnostics to read error codes. Pay attention to system health during regular maintenance to avoid a lot of trouble. Safety first—don't risk big losses over small issues.
