  • Hi Jerry,

    My guess is that you have a problem with the throttle pedal accelearator. The sensor is located in the engine bay, near the brake booster. At least on the W210 that's where it is. I think on the W208 it is on mounted on the same location.

    The cable from the gas pedal connects to this sensor. My recomandation would be scan the codes with a professional scanner first.

    Throtle sensor
