I doubt it's your OBC
According to my mechanic this OBC stays on 24/7 and that is why the battery is drained, any other ideas?

Is there a fuse for it ?

How many milli amps does it pull? More than 1 thing stays on all the time. Place an amp meter (multimeter set on amps) between your battery and the battery positive wire. See how many amps are being pulled with key off. Then start pulling fuses to see what item is drawing current. There is an "x" amount always being drawn - I forgot what that is.
I'm with aaverhulst, you're chasing something that may got through the On Board Computer. With the amp meter connected, start pulling fuses and relays. My guess is you have a relay hanging on.

doesn't that screen show time even when the car is off? I cannot remember because the ones in my two kid's cars don't work
No e30s again.
The OBC is always on although the backlight is only on with the car. Current draw is negligible. Assuming it works properly when the car is on then it's working properly when off too. The most common cause for excessive draw are aftermarket electronics. https://www.bimmerforums.com/forum/s...2#post28762142
