Electronic Stability Program (ESP) Switch Genuine Mercedes

This is a genuine Mercedes-Benz Electronic Stability Program (ESP) Switch for R129 SL-Class vehicles. ESP was standard on all SL600 vehicles 1996 and later and optional on the SL500. If your vehicle does not have ESP, it will not have this switch. All R129 vehicles had ABS and traction control systems that work on the front and back axis, but the ESP anti-skid system works on the left and right axis. It gives the vehicle added traction when side-skidding occurs. The system uses sensors to monitor steering angle, each wheel speed, lateral acceleration, and brake pressure to determine if the vehicle is sliding. Then, the system applies brakes to the wheels individually to help maintain control of the vehicle. Bosch's Electronic Stability Program was the first to reach the market, which appeared on Mercedes-Benz S-Class vehicles in 1995. It then reached the R129 SL-Class in 1996 and other high-end automakers began implementing such features ever since.
