    The dreaded MK5 Golf GTi battery drain.

    Hi People,
    We have a 2006 MK5 Golf GTi, with a stage 1 remap. It has the terrible battery drain problem, a friend who has a VCDS cable and program advised us to change the Gateway Control Unit to a newer/upgraded unit, so we fitted a 7N0 907 530 AG. After fitting the unit the battery drain is still as bad as ever, with the car locked up, including the bonnet latch and everything switched off I am getting an amp reading of 2.105. Should we start looking for broken door wires? Any suggestions would be very much appreciated.

    It's a terrible problem that spoils such a great car......

    Removed.  Data from a clone/pirate copy of VCDS is not welcome here.
