Mercedes-Benz ML430 persistent ESP light issue despite new brake switch and sensors on Mercedes-Benz ML430

Some Mercedes-Benz ML430 owners report experiencing a persistent ESP light issue even after replacing the brake switch and sensors. This problem may be attributed to faulty yaw or wheel speed sensors, which are essential for the Electronic Stability Program (ESP) system. Additionally, owners are advised to get fault codes read from the ESP module to identify specific sensor malfunctions or other underlying issues. Low battery voltage is another factor that can keep the ESP light illuminated, highlighting the importance of maintaining a properly charged battery. For those unable to resolve the issue on their own, seeking professional diagnostics is recommended, as technicians can provide comprehensive checks and utilize diagnostic tools to pinpoint the problem. Some owners have also found temporary relief by resetting the ESP light using various methods, although addressing the root cause is crucial for a lasting solution.
