Hello, I own a 2007 x5. I am plagued with the problem of periodically losing battery power that is causing warnings about losing traction control, having transmission warnings, and even temperature warnings. The vehicle will self regulate speed and performance until it is poo off. A quick charge to the battery fixes the problem for a while till it happens again. I have replaced the battery, throttle body and harnesses and have replaced the radiator and coolant pipes. I cannot find what is drawing on the battery. Any suggestions?
