The front right ABS sensor wire needs replacing but there may be more issues. In short, a snow chain snapped and cut the wire. The car now shows eight warning notifications: three of these directly relate to the wheel: ESC control, hill start assist and tyre pressure loss indicator. The other five are: lane assist, front assist, electronic parking brake, headlight range control and parking distance control. I have removed the wheel and there is a clear cut in the wire. Replacing the sensor is easy but does anyone know if it is possible to replace the wire yourself? The wire disappears through the wheel arch but I cannot see where I emerges. Could the five faults be related to this also?
