0.5 Amp battery drain on BPM (fuse 5 LH HB)
I have a 0.5A battery drain on the BPM circuit (fuse 5 LH heelboard).
Have been hunting through the car and found zilch so far.
I was thinking that the rain might have triggered this so opened up all the door cards and checked if there was water in the connectors perhaps - no luck there though.
Does anyone have any ideas of how to approach this?

Maybe; let's hope that's all it is.
Quick story: years ago, in Japan, I had a 10 year old BMW 2500 that was killing batteries right and left. I couldn't find the draw: a CPO who had repaired German cars part time while stationed in Germany, told me it was the trunk light: "It is staying on!" I put my 6 year old son in the trunk and told him to pound on trunk lid as soon as it got dark: "Don't be scared." No pounding came. How come: "didn't dark Daddy, the light stayed on. Ran the crate for five more years on the last 'BAHtry' I paid for.

Are you taking these readings just after shutting the car down?
It takes quite a while after the turn off of the ignition until the computers go into shut down mode.
They take their command to go into a timed shut down sequence from when the key is withdrawn from the barrel.
There is a little flap that covers where the key goes in, make sure it covers the hole when the key is removed.
I think it is somewhere on this forum the shut down times, if not try the JTIS or jagdocs.com.
