In other words, is it the OBC that is stopping ready, or is something else stopping it?
We waitied two weeks with the service plug disconnected last time
The temporary fuse still has continuity, in fact without the contactors closing it hasn't even seen voltage.
We tried disconnecting the OBC comms connector (E-02?), however the car still wouldn't go into ready.
I guess with the fuse open circuit it could eliminate a ground fault, and it is possible we introduced one in working in the charger.

You certainly know your way around the service manual!
Interesting - however our original fault codes led the dealer to want to replace the charger first. I'd have to review if we had an internal OBC code 02 - the print out is with the car.
We also noticed for the P0A09 the high voltage level check is done via the MUT-III, which presumably uses the BMS taps, and doesn't rely on the contactors operation.
