My 08 e92 M3 has been acting weird lately. It's needed a jump start a few days ago and I took it for a nice 30 min drive to recharge the battery after. 2 days later the battery died again and I got a jump start from my neighbor. This morning the car wouldn't start again and I tried getting a jump start, but that didn't work either. The car just goes "click" once and won't start. & I don't believe it's the battery as all the ignition stuff works and the headlights are able to be turned on. Please help??
