vauxhall vectra 2.0 dti?

you dont say what year your vehicle is so assuming its a vectra c ie 2002 onwards turn on your sidelights /put your foot on the brake pedal /press in the button on your dashboard /now turn on the ignition .do not start just turn on and keep your finger on the reset button for about 10-12 seconds it will reset
