greetings, my sl 600 1995 has ABS and ASR lights came on after the shop changed the rear rotors and front brake hoses. Also the speedometer was moving erratically up to 40 mph when the car was in standstill. The car soft software showed that the front left ABS sensor was faulty solenoid on the rt passenger was bad. Both front speed/ABS sensor were changed but did not solved the problem. now a rescan showed that master cylinder valve was bad. what should we do now? any comments will be appreciated.
