This is what I did, but I disconnected the battery (jumper on DVM) before each wire disconnect-reconnect since I found that it was a bit tight and didn`t want to touch some metal parts with my ratchet.

Turbobimmer Hi, I bit the bullet and spent ahhhm a good 5 hours testing fuses in the X5 whilst having the multimeter wired up in the battery circuit....(took 5 hours cos i kept on accidentally waking X whilst fiddling in glove compartment and having to wait 16 mins for it to sleep over and over and over:yawn:)

found that sleep mode drain was 70ma (0.07amps) I pulled fuse 83 out of the rear(which is the dc socket power rear luggage compartment) and it dropped to 0.05amps although small was a start....put fuse in and was back to 70ma

pulled fuse 43 (fuse 1,43,45 = instrument cluster) again a drop from 0.07 to 0.05

With both the fuses pulled I am looking at a 30ma sleep mode drain which is ok , but I cant really do without the instrument cluster...whats nuts did OBC test no.2 to test cluster and all chec out ok....does anyone have a substantive fuse-circuit diagram for the x5? I need to know more about fuse 43 and where it ties in


what was you drain like caused by the boomerang? wasa it in the 1plus amp range?

omodos, if I remember well, the current draw with the tracking device connected was quite high, like over 100mA.

I find strange that disconnecting the DC socket makes a change (if there is nothing connected to the socket). Unless the circuit is shared with something else.

At 70mA, with a good battery and daily driving the vehicle, I don't think you will have problems.

For the schematics, look on the first page, Qsilver7 is posting a link to the online diagrams. Need Java installed on the computer.

Also, check your BMW Bluetooth module (if you have one). Mine created a current draw, maybe 6-8 months after I repaired the tracking device current draw. I simply removed the module since the quality of the conversation was not very good.

thanks sir, ok the dc socket in the rear wasn't working anyhow so removed the fuse until I rip of panel and see if anything is being fed off it....going to get the battery load tested Friday and then if that checks out it maybe the starter sapping too many amps on each startup! I have found numerous posts on this on x5drivers uk site!

2001 4.4 i dont have this unit

hi there thanks, what unit? you mean the dc socket at rear not beign on 2001 4.4..either way hoping some guru will read my other post on using a clamp meter...general consensus is my sluggish starts maybe caused by excessive amp draw of starter, bearing in mind i have a 50ma sleep mode drain + good battery+good charging system ...cant think of anything else....IF i used the amp clamp correctly then I got in excess of 392amp or over on cranking engine and starting!
