A week ago all these came on - stopped the car for 10 mins and when I re-started it they all came. Yesterday took the 2 rear ABS sensors off and cleaned them up. Lights still on and TCS ABS not working. Do you need to clear the fault for the systems to recognize the problem has been fixed? If so how? Or if they self-clear then I assume there is still a problem. In next week for the annual service/MOT so they can fix it but would like cut down the £s if I can.
