Unhappy HELP? Where is my O2 sensor?

Hello all,
Ive been trying to find my O2 sensor on my car. I've searched all sorts of threads and youtube links and no one has the same engine as me.

Symptoms of my car is that after a 45min of driving on freeway my engine cut off and ive had to pull over then start it straight back up again. This has happened a few times now.

This thread: http://www.bmwland.co.uk/forums/view...p?f=4&t=118630
makes me believe its my O2 sensor.

anyway i attached a picture of my engine. If anyone knows where it is could you let me know.
