Not trying to Hijack your thread but I am having the same issue on a 2007 328i. I have a neighbor who's granddaughter owns a 2007 328i. She came out one day and the car has no power at all got a jump it fired right up she drove it for the day and parked it. Came out a few hour's later and the car has no power at all no dome light , no locks, no trunk light, nothing I have checked the battery and the post under the hood and all checks out fine. I have been pulling my hair out for 5 days now over this and have no idea what is wrong neither does the dealership. I removed the battery took it to a few places and they say the battery is perfect. Any help would be greatly appreciated.
