guys i have 2006 bmw 530i it drains the battery over night. i think the problem is with the sleep mode. on my car start push button and green light on headlight switch glows green. when i shut off the car they shut off too after couple minutes however i went back after an hour or so. both of the buttons start glowing and shuts off after a minute or so and start glowing again. it goes in the pattern. is there any fuse i can pull out to disconnect that sleep system. or any other solution will be appreciated. thanks jag

How many miles do you have on your car and when was the last time you changed your battery?

My 06 530i with about 78k kept dying after 2 mins of listening to the radio without the engine on. Or after 3 days of sitting idle. Changed the battery, haven't had a problem since.
