    I've left mine overnight which resets it

    Obviously if the faults still there it will come straigh on again

    This on a MK4?

    How do you disconnect the battery without the alarm going off?

    Welcome to AOC Tom

    Turn the key in the ignition till the dash lights come on, remove the key, then you have 10-30secs to disconnect the battery.

    Or some people just leave the key in the ignition while disconnecting the battery. Both methods should work.
