when i start my 95 525i it starts and runs, but die within 3 to 5 minutes. Also the info center reads.." brake light circuit" and the brake lite does not work. After a boost, the "brake light circuit" clears and the brake lite start working again.
I suspect a weak or dying battery but I would like to know if there maybe something else that could be causing this problem... I dont to go buy a new battery and still have the same problem. My wife drives that car and I would hate to get her stuck.
