Hi All My W203 C180 (2000) has developed a serious problem with the throttle sticking. Driving back from local shops last week throttle suddendly jammed...........went past my house at 140MPH with very braking doing very little. fortunately there is a field with a steep encline nearby managed to get it out of the residential area and onto the field (meant going round a roundabout at about 100mph). It has only done it once since then and this time i noticed it's when the kickdown is depressed. any ideas guys ?
