I drive my 2006 325ci everyday and recently it has acquired a battery draw that is killing the battery overnight. I originally thought it was the battery being old (7 years old) and have replaced the battery. I drove the car for an hour around town, parked it overnight and the battery doesn't have the juice to start the car. I do not even know where to start looking for an electrical issue. Any advice? Thanks
