Mercedes-Benz CLK500 ESP module failure causing various warning lights and electrical malfunctions on Mercedes-Benz CLK500

Some Mercedes-Benz CLK500 owners report experiencing ESP module failures, which can lead to various warning lights and electrical malfunctions. These issues often manifest through the ESP malfunction light, indicating problems with the Electronic Stability Program that is essential for maintaining vehicle stability in adverse conditions. Common causes for the "ESP Inoperative" warning include sensor failures related to wheel speed, steering angle, and yaw rate, as well as electronic module issues within the ABS and ESP control modules and battery voltage problems. Owners may find that failed components trigger these malfunctions, and using a diagnostic scanner to read ESP fault codes can help identify the issues more accurately and cost-effectively. Additionally, pressing the "ESP Off" button can disable the system, causing the warning light to remain illuminated for various reasons. A faulty brake light switch is another frequent culprit, often triggering ABS/BAS/ESP warnings, but replacing it is generally a straightforward and inexpensive DIY task. These factors collectively contribute to the potential for ESP module failure, impacting the vehicle's stability and safety on the road.
