link is in german...
but position "0" on the ignition key means "all power off". So IMHO its the same what you would like to know. The link describes the power consumption on a car, where the ignition Key is not in the lock.
You also can test it with an ampere-meter:
1. disconnect "-" from battery
2. connect an amperemeter (f.e. 10 A) between "-" on battery and the brown wire
3. disconnect the both lamps of the luggage bay (need to be opend to watch ampere-meter)
4. pull out ignition key
5. close all doors
beginning 2-4 A, few minutes later 0,6A and after all a 0.03A - this is a normal value.
Whith this consumption a 90AH Battery could last about 83 days before it wents broke.
Original: "Will sagen: nutzbar sind vielleicht 60Ah.
So, bei 0,03ADauerstrom dauert es also:
60:0,03 = 2000Stunden = 83Tage, bis sie leer ist. Bzw. bis sie in die Gegend der Tiefentladung kommt."
