    Ok so I've done a bit more digging and found quite a few draws from the battery.
    Left hand heelboard.
    .38 mA draw in total
    F6. 0.02 reader exciter centre console s/w
    F5 0.22 body processor module
    F2. 0.01
    F1. 0.04
    F13 0.01
    F15 0.03
    F18. 0.42 then reduces to 0.05


    Boot fuse box 0.02

    Right hand heelboard
    0.07
    😭
    Guess the first thing to check is the body processor module.
    Any ideas how to get to it? RHD so somewhere by the glove box I guess

    Did you wait 15 mins for things to shut down.
    Yes, remove glovebox first.

    Hi, Andy, thanks for that 🙄
    Just reconnected the fully recharged battery, then shut myself inside the car and waited 15 mins. ( something to be said for this self isolation stuff atm) and all fuses dropped to 0 apart from the bcm which was at 0.01

    So we start again.😎
    I think I'll try to disconnect the alarm chearper next.

    maybe check at the battery after 15 mins ?

    do you have a current clamp.

    This is an easy way to check the thick cables (to locate to a fuse box or alternator etc)

    Andy, if I wanted to check the current draw with the boot shut and alarm on, would this do the job? I think I might need some sort of extention kit so it can be outside the boot when it's shut/locked ??

    If you press on the latch n with your key blade, the car will think the boot is shut.

    Try not to slam the boot down when you do this!!! Leave your key in the latch to remind you.
    Before shutting the boot at the end, open the boot in the normal way

    Hi again.
    Just to keep you all updated, I've had another go at tracing this darn drain.
    It is the BPM. Without the BPM fuse in, the drain at the battery positive is 0.08.
    0.25 with it in.
    Any good info on how to take the glove box off🤔🙂. Haven't even looked yet tbh😁

    Another update. I took out the BPM, and have found that there is damp in the socket of the unit. Opened up the unit and all is dry, so really confused as to how I can get damp in the connection as it's at the bottom? I will dry it out and then see if there is still a draw, and if so where it is from. I'll try to attach a photo I took in the connection.

    Final update (I hope)
    Dried out the conection to the BPM. Reconnected

    All is now good. Now need to work out why it got wet in the first place? It is kept in a garage, and dont drive it in the wet if I can help it. so a bit puzzling.
    These cars are beautiful, but need alot of TLC.
