    Very easy to do mate
    1, remove rocker cover
    2, disconnect each injector plug
    3, undo the 10mm nut/bolt on the end of the head that holds the loom plug
    4, compress the 2 metal spring clips that hold the loom in the head
    5, slide loom out
    6 slide new loom in, connect injectors and refit in reverse order

    :)

    Good stuff.

    After changing the loom will there be a fault code appearing?

    Shouldnt be from changing the loom, although you will prob have a stored code of the injector thats causing the misfire, mk5 golfs do, unsure if the mk4 platform cars do tho
