Hey erybody!! I have a question to ask!! Okay so I have a battery light on in my w211 e500 and I ran some test and my trunk battery is fine and the little baby battery in my passenger seat is brand new and I ran a alternator test and voltage regulator test and they are all working perfectly fine but somewhere or something is draining power out... for instance Ill leave my car sitting over night (11-12 hours) and start it in the morning and it keeps saying low battery functions temporarily unavailable then I drive it like 5 miles and everything works again... I live in N.C. and there isn’t really anyone who knows much about my car. What could it be?? Possibly battery control module or what idk lol
