My lovely C200 recently developed a permanent ABS warning light.
The light came on after stopping, i.e. without moving off. It is now a permanent feature.
I have checked the OVP output to the ABS control unit - 14.2v with the engine running.
Am I right in thinking that because the light comes on before the sensors are activated, then it is more likely to be the ABS control unit than a sensor? - or will a short circuit or open circuit sensor cause this too?
I have checked the physical condition of the front sensors and rings, all looks ok. I'm not too sure how to separate the front sensor plugs at the wheelarch - ping the wire clip off and pull hard?
