Been fighting this for a while.
Alternator and battery good.
Pulling all internal fuses does not remove drain apart from ECU and memory contributions.
Pulling 60a maxi fuse for ignition circuit in engine bay makes it go away.
Is it likley to be the ignition switch below the key barrel in the centre console or something else down stream?
Doing my head in as pulling the internal cabin fuses has no influence at all!

Thanks for any help and suggestions!

Try disconnecting components alternator,starter,air con comp,etc,it maybe the ecu ,would not rule anything out,but looks like you are on the right track.
