not a BMW expert but had this same problem, it has to be very near the battery, best advice is follow the 12 volts out and look first for a bad cable (positive is more common but neg can do it) that is broken inside, In my case it was right where the Pos cable came off the battery, 2 inches away at T junction where the cable splits and there were two cables ---voltage the battery and not four inches to the left of it.A volt meter will save a lot of time.
