Just tinkering with a lower than I'd like battery voltage on my B7 S4, so started measuring.
Drain with everything off and asleep is about 30ma, and I've never had any problems overnight etc, so that seems fine.
But its the battery drain with the ignition on that seems higher than it should. With ignition on, but everything off (radio, heater, seats etc), I'm drawing 9A. Doesn't that seem a little high? I mean what the hell else could be on that draws 9A lol? Although the RNSE is switched off, its still actually on until it sleeps, and that is drawing 3A, so I've got 5A of unaccounted for current lol. I've been through every fuse in the drivers side dash, and nothing is anything like that, so a bit stumped!
If anyone knows what the acceptable draw should be with the ignition on, that'd be great
