Where is the oxygen sensor in a 2001 volkswagen gls turbo new beetle?

I need to know where the oxygen sensor is so that I can replace it. Can anyone tell me where it is, or tell me where I can find this information?

done
oxygen or lamba sensor, will be located in the exhaust down pipe before the catalytic converter, follow the wires from the sensor to the jack plug, separate jack plug, now undo sensor without the wires twisting .Insert new sensor tighten but not excessively reattach jack plug connector.
