Parasitic battery drain - please help

[cornontherob]

Check individual circuits, did you put a new radio in or something? Clear any codes, see if that changes anything

No, No new radio etc.

I pulled all fuses the other day to find nothing, however I tried again today
When I pulled C3, (central Locking etc) draw stopped.

When I look at the circuit diagram for Central Locks Alarm System, wow, where does current enter that diagram?.

No clue what it could be now?

Thanks for your input
