Hi Guys I live in Mandurah W.A. Does anyone know of a Mechanic or Workshop in Mandurah or Perth that can fix my ABS & Trc light problem seems to be a speed sensor in the front wheel problem or the Nitrogen accumulator seal is RS Many thanks

Trc & ABS warning lights go on and off whiring sound comes on quite often (Brake helium Pump???) Any ideas how to fix it Many thanks
