It is very prudent and sensible of you to have concerns about this.
I would check with BMW service if that is an issue with that system and, in particular, whether or not it is an indication that the there might be an impending failure. Unless there is some kind of back up key that can enable you to operate the ignition and starter motor to start the car if the starter button fails, such a failure will leave you stranded. On some vehicles with this starter button system, failure of the starter button definitely will leave you with no other way of starting the car..
12 volts when? going up or down? both windows? check the switch. the black wires coming out of the switch is ground. if those have power, then check the ground connection. G201 is near the left side of steering column. the motor should have power on one wire and the other is ground, they just swap to go up or down. I suspect the switch is bad.
WHEN ENGINE WONT SHUT OFF ITS CALLED DIESELING.WHAT POSSIBLE CAUSES IS.HOT SPOTS IN ENGINE DUE TO CARBON BUILD UP ON PISTONS AND VALVES. INJECTORS LEAKING FUEL.THEN THE HOT GLOWING CARBON IGNITES FUEL FROM LEAKING FUEL INJECTORS.THE ENGINE WILL KEEP RUNNING.WHEN YOU TURN IT OFF.
check the ignition wire from you solenoid to your ignition in the column they usually have a fusable link since the 302 is harder to turn over than the inline six you probably just blew that fuse or burnt the wire the easiest way to check it is follow ur third wire on ur solenoid its like a 12 or 14 guage wire and check for charring or hopefully for ur sake a fusable link
You need to jump the neutral safety switch there was a plug you disconnected in front of the shifter it has either 4 or 6 pins, take the plug you pulled out cut it off of the old gear selector and plug it back in and strip the wires back, the wires are color coded so like colors usually go together. with a 12 volt test light ground the clip to a proper ground, turn the key to the start position hold on start and check for voltage at the wires you previously stripped, let go of key and voltage should stop if voltage is constant you may be on the reverse light circuit, keep looking for voltage that goes on only when key turned to start, when you find it look for the corresponding color ie green /white to green/ black etc, wire the 2 together and starter should crank over, if not try another one. you will also need to wire the reverse light switch from the new trans to this connector. stay away from brown wires as they are grounds on bmw and never hook anything but brown to brown unless you are 100 percent certain it hooks up that way
