2004 Mini Cooper oxygen sensor
 

I received the following fault code:

P0130 O2 Sensor Fault (Bank 1 Sensor 1)

If I am correct it should be the pre-cat sensor; however, I do not know where this sensor is located. Could someone post a picture or video showing it?

Also my car has two oxygen sensors, correct?

The sensor is located just above the cat and right after the exhaust manifold where it comes out of the engine. Not real easy to get to. I just changed one there. You have to do it from under the car.
