You need to purchase the tool for removing the O2 sensor. It's a socket that has a slit down the side for the O2 sensor cable. This will cost you about 20-30$. The 02 sensor will un-screw with a socket wrench. Best done when car is cold. Otherwise you will burn your hands. Good luck.

No. do you mean the front or rear o2? The front might be an A/F sensor. Big difference. But no, there isn't.
On a 2001 VW Jetta 1.8T (AWW) Wolfsburg Ed. it's right next to your intake manifold.
That is the O2 sensor behind the catalytic converter.
P0133 means "Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 1)." Your car may be running rich and using excess fuel. Check the O2 sensors, especially the first O2 sensor before the cat, and check to be sure you don't have any exhaust leaks. I had this code appear once on my 2002 VW Jetta 1.8t, and replacing the front O2 sensor fixed the problem.
