    Default Disconnecting Battery

    Hope somebody can help, just done a airbox mod to my 2.0 dti veccy. I've heard that you need to disconnect the battery for some reason, something to do with the ecu. Does anyone know if this is true. if so, how do i disconnect it. cheers.

    Just unplug the Neg for 15-20 mins mate. All it does is help the ECU to re learn any new parameters.

    Just make sure you have your stereo security code to hand before you disconnect the battery.

    Also, depending on how old your Vectra is, you will have to switch on then off your ignition and disconnect the battery within 15 seconds otherwise the alarm will go off.
