Hi, I just crashed the front of my 2004 530d and the air bags came out. The car will not start now and I was wondering if anyone knows where the fuel cut-off ( inertia switch ) is located in the car???? Please help... Thanks

New model BMW's have what they call a Battery Safety Terminal(BST) when the front air bags pop the engine gets disconnected from power.
THE BST is a connection to the battery that it set to explode (small explosion) so that the cable feeding pwr to engine from batt is discounected, this is done to reduce risk of fire

alll other systems in car will recieve the 12 V they need
