Car Forum / Mercedes-Benz Cars / July 2007ASR/ABS lights
The ASR and ABS lights on a C200 estate stay on after ignition. Cruise control no longer works. I am told this is likely to be one of the ABS detectors/Speed detectors on one of the four wheels. I would be grateful for anyone's thoughts on this diagnosis. If it is the case how can I ascertain which wheel's detector has failed? Finally are the detectors difficult to fit? Thank you. -- Robert > The ASR and ABS lights on a C200 estate stay on after ignition. Cruise > control no longer works.

If it is the sensors they are just one bolt, but you need to check their resistance before replacing any, they aren't cheap - cleaning them out (and the toothed ring on the wheel ) may help hth cheers How about when you shutdown and restart right away? I suspect it is the battery too. If the light[s] do not go out after starting, you have a power supply problem. If the light[s] go out after starting but come on after the car moves, you have a wheel speed sensor problem. The system does not know a sensor is bad when you first start the car. The car has to move and the sensors have to send back a A/C ~ voltage signal. No voltage = light comes on. In your case, do NOT throw money away on sensors. You have a voltage supply problem. > The ASR and ABS lights on a C200 estate stay on after ignition. Cruise > control no longer works.
