Hello. The title contains a lot but I think it's all connected. My question is below my 'quick' explanation.
My battery drains in a day or so. I've checked current battery but also replaced the battery, just to be sure. Both do the same.
I read this post>>

which mentions the fuses which seem to be giving me problems (36 & 42) and the same symptoms - high amps when locked. Remove these two fuses and it drops.
Following the great fuse guide by Sarge >> http://www.a2oc.net/forum/showthread.php?10712-Fuse-box-Fuses-Fuse-Ratings-Fuse-Locations
it says:
36 - Heated Rear Window Relay 10A
Convenience System Control Unit
Control & Display unit for Air Conditioner/Climate
Tank Filler Flap Release Switch
Additional Heating Button (ECON)
42 - Convenience System Central Control Unit 10A
Anti-theft Alarm Ultra-sonic Sensor
So, then reading another post in the same thread as above:
http://www.a2oc.net/forum/showthrea...in-in-4-days-how-to-trace&p=186930#post186930
suggests the Convenience System Central Control Unit.
With the fuses in, disconnecting this doesn't seem to make the same difference.
I see, looking on ebay, that there are similar units in the OS & NS doors.
My question(s) ... finally
Do both the NS & OS units do the same thing or is the OS one the main unit?
If so, could this problem be the NS side?
I have the drivers door card off but not the NS door card. I don't want to remove it if I don't have to.
The part number of the OS unit is 8Z2 959 802
Thanks in advance
edit: reading another thread, there is talk of the comfort control module under the NS floor. I was getting confused with that and the module in the door. How do I check both?
