which plug was hanging off? i have the problem with the abs not working and light staying on and i dont have a manual for the cargeoff pine said:Before you spend any money sorting this out i would just check that the plug is pushed all the way in.I had the abs light on for eighteen months changed abs ecu i even bought a machine that you plug in to the car to fault fine the abs system.Then some months latter looked under the bonnet and found a plug just hanging there pushed it all the way in and the abs light works and so do's the abs.
