hey guys, recently changed the driverside front hub on my 2wd cosworth & tryed to get the abs sensor out but ended up breaking it in process. i had a spare sensor from a 4x4 sapphire cosworth so fitted it & now abs light comes on. it goes out as normal when i start the car but when i drive it & brake the pedal kicks back then the abs light comes on. any ideas? is the 4x4 sensor different in any way or could it be the abs ring? thanks.
