Why is battery monitoring/energy monitor ecm not shutting down all ignition circuits when quiescent voltage drops below threshold to ‘save ‘the battery ?
Can you use a shunt inline with battery lead and measure the drain whilst car is asleep , roll boot latch over and wedge the spring loaded press in type switch on boot lid .
After say 20 mins see how many amps it’s pulling out , see if amps is a steady draw or doing any cycling or surging .
My a8 used to have dickie door handles and would wake up through the night when it was raining, but energy monitor would always clip it and I never had a flat battery on it .
I’m wondering if the body module not going to sleep ( gear stick back lighting staying lit ) is a consequence of another draw on a circuit that is not isolated by the energy monitor ecm .
