FWIW I've read that the 12V issues we're having is from modules not properly shutting down or more accurately not going into sleep mode where they don't draw much if any power. Often this can be cured with a simple power cycle of the car which is why the dealer may not be able to find anything. other than some DTCs about low battery voltage. I'm guessing the audio module "crashed" and never went into sleep mode draining your battery. The ford spec for sleep mode when the car is off is 50ma but it may take up to 40 minutes to get down to that low. If it doesn't drop down you have a misbehaving module. I measured mine at a little over 3A immediately after turning the car off and then 20mA after 40 min. FYI disconnecting the battery to hook your meter up in series with the battery resets the 40 minute clock.
@traingles how do you recommend I do a simple power cycle of the car?
