It has four. The first two are called the pre-cat (catalyst) or hot side. They are located under the hood on the left side (when standing at the front looking at the motor) on the exhaust manifold. The other two or called the post-cat or cold side. They are in the exhaust pipes coming down from the motor under the car at the passenger side. Replace them with genuine Bmw parts. They are more expensive but you won't have any issues. A lot of problems come from aftermarket sensors because the calibrations aren't the exact same.

We do not have thses diagrams. There is a sticker under the hood that has the routing diagrams.
