Hi Guys please can someone help me out. I got abs light and traction control light on permanently from moment you start car. Checked brake switch that's fine,cruise control works fine as well. Only thing not working is abs and traction control. Had local garage plug car in on reader and said couldn't connect as he thinks there is a blown abs fuse somewhere. Is this true as I have searched high and low and found no fuse. Possible fault is speed sensor is there a way I can check those myself? Also will a 1997 c280 sport have a sensor in the diff? Any help will be much appreciated thanks guys.
