    Resetting ECU

    Are there any other ways of resetting an ECU to clear fault codes, after changing the AFM, etc, apart from either disconnecting the battery or using a Tech 2?

    Can you pull out a fuse or disconnect some wiring to the ECU itself?

    Cheers,
    Craig

    Thanks guys, next stupid question, how the hell do you get those big plugs off? The metal clips won't budge and I've pushed in the small plastic clip holding them in first.

    they can be really tight but make sure you push the black tab in the middle first cus they do break easily, then prise the metal clip right up
