2 Answers
Methods to reset the ESP warning light on a Mercedes-Benz: 1. The driver accidentally pressed the ESP off button: Press the menu button on the left side of the steering wheel, then use the up and down keys to select the assistance option and press the "OK" button, finally select the ESP off option. 2. Poor contact of the wheel speed sensor or a broken signal line: After checking and repairing the fault at a 4S shop, use a computer to clear the fault code. Taking the Mercedes-Benz C-Class 2021 C200L Dynamic Sport Edition as an example: It is a mid-size car launched by Beijing Benz, with dimensions of 4784mm in length, 1810mm in width, and 1457mm in height, and a wheelbase of 2920mm. It is equipped with a 1.5T turbocharged engine, delivering a maximum power of 115kw and a maximum torque of 250nm, matched with a 9-speed automatic transmission.
I've had my Mercedes for almost ten years now, and the ESP light has come on several times. The first time it happened, I was a bit panicked, but later I learned how to handle it. The light usually indicates a dirty sensor or a short circuit issue—for example, if the wheel speed sensor gets muddy, it can trigger a false alarm. To turn off the light, try a simple fix first: turn off the engine and restart the car. Sometimes, the computer system resets itself, and the light goes out. If the light remains on, it's best to use an OBD scanner to read the fault code. You can buy an affordable handheld device online and connect it to the car's port to read the code. Once you identify the specific issue, address it based on the code. For instance, if it's a sensor problem, you can replace it yourself—it usually costs around a hundred bucks. But don’t be overconfident; if the light flashes or the system doesn’t respond at all, prioritize safety and take it to a dealership for professional diagnosis. ESP is safety-related—driving in the rain without it can lead to skidding. Every time I get maintenance, I remind the mechanic to check the sensors—prevention is key.
