Hi everybody,
Just found this community, in desperate search of a solution for my problem. Seems a great place with answers for all sort of problems, I hope to add my part.
My E34 lost all power, basically the car battery is dead after not being used while on vacation.
Last time I had this problem, I succeded by wiring a cable from another car's battery and connecting it to the light source from my car's trunk. This supplied enough power to open the doors. At that time, the car trunk was left open, so the light was ON.
Unfortunately, right now everything is locked, including trunk and lights are OFF. I tried to connect the wire from the battery to one of the lights from the license plate, but because the lights are off, this is not working.
The alarm was supposed to be dead, but I cannot think why the BMW engineers would've chosen to design an electrical key locking system instead of a mechanical one. Is it something I am missing here?
Any tips and advices about how to open the door without smashing a window, would be REALLY appreciated.
