Mercedes-Benz E350 ESP light activates intermittently while driving, requiring restart to reset on Mercedes-Benz E350

Some Mercedes-Benz E350 owners report experiencing intermittent activation of the ESP light while driving, which may require a restart to reset. This issue can indicate that the Electronic Stability Program (ESP) is actively working to stabilize the vehicle during emergency maneuvers or on slippery surfaces. Common causes for the ESP malfunction light include faulty wheel speed sensors and battery issues, both of which can significantly impact vehicle safety and performance. Additionally, some owners have found that accidentally hitting the ESP button on the dashboard can cause the light to remain on constantly; pressing and holding the ESP switch for three seconds may help turn it off. Wheel speed sensor replacements are often necessary, as they can lead to intermittent warning light issues, and under/over voltage problems may occur even with a good main battery and a new auxiliary battery. It is crucial for owners to monitor alternator power levels, which should typically range between 13-14.65 volts, as failing wheel speed sensors can trigger warnings similar to those associated with the ESP light. Addressing these concerns promptly is recommended to ensure safe vehicle operation.
