E34 current consumption ?
How much E34 should consume current with ignition, all interior lights off? Any reference value ? Either I have bad battery or some gadget is leaking..

The E34 should only draw a few mA with everything off, if you are reading anything more than about 10mA, then start removing fuses till you can find out what.

Bought a new battery and no problems in 2 days. With this new battery I was getting around 500mA measured from battery's negative hub to negative wire. But then I did not know the 16 minutes 'consumer cut-off' from the second link Shogun posted.
Where's the voltage reading from OBC test 09 coming from ?

exact measures via testing with an ammeter:
Car with all modules pulled: 20mA
Car with all modules put back in except GM: 20mA
After insertion of GM: 170mA
After letting the car sit for a while in that state: 60mA
it never dropped below 60. the draw values included removing the fuse from the radio, so 20mA just for the DME/TCU, meaning the GM draws 40mA by itself, and uses an additional 110 for LED lighting for that 10min or so period before they turn off.
