Anyhow found the radio fuse and it is drawing 1.2A with radio on silently, drops to 0.5A when radio switched off and then to 7ma after half minute or so. So it is not radio drawing current on mine. 150ma is a bit more than I would like but car still starts fine after 2 weeks without use and on old battery so cannot really complain.

thanks! 7mA sounds like the sort of figure I would expect , but 4 times as much , as I have ??? sounds like enemy action ! if I had your radio [ do you have a concert ? ] it would solve my problems ! I didn't realise that you could change the settings from standard to bose , my system being standard if it has been changed to bose it might have caused the problem [ can't check , don't have the kit ] ; as the radio is constant live could maybe find a way to put a switch in the circuit to isolate it , sounds like mine isn't switching off !
you say that the car starts fine after 2 weeks at 12.2 ... I have been checking the voltage drop over 4 days and it is down by about .12 volts so starting after 2 weeks would be about 2 weeks might be possible from what you say , would probably need 12.3 with winter temperatures where I live even though I head for the sun when it starts to go below zero !
anyway have started again , put the battery on charge and will test daily for a couple of weeks , my 90 quattro 7A 20valve may be on it's last legs but fine for running around locally which is all I need until I go to england to visit my daughter in the new forest in july
don't forget to post what your problem was when you discover why your drain is 150mA
ps , maybe the reason that the other A8 you looked at didn't have a side panel was because the owner needed frequent access to the battery !
