After many hours of measuring and searching through schematics i finally found a very simple reason why the battery drained. When i looked under the dash i hit something warm with my left elbow and thought hmm, heat means electrical current. Turns out i left the wifi obdII dongle in the socket after reading some error codes about 3 months ago. The worst thing is i didn't even remember this so i guess my only excuse is that i'm over 50. After i removed the dongle the currency draw dropped to 20mah instead of 120 as before. Tested to remove the fuses and the FP/ASD didn't make a difference but the 40amp big fuse reading lighting made another 10mah difference. So the question is does anybody have any idea what's hidden under the lighting "big fuse" that could draw the remaining 10mah and it's not the radio?
