I had a 1987 Jetta and the oxygen sensor was connected to the down pipe. It is screwed in and there should be a wire leading from it. From the engine compartment you can look near the firewall and follow the exhaust pipes. It should be sticking out midway between the top and bottom bends.
The oxygen sensor on a 2004 Volkswagen Jetta is located in the engine area. It is usually encouraged to warm up the engine so as to ease the threads.
Take it to the dealership.... Its real simple take the car jack it up take off the housing cover where the oxygen sensor is at then un plug the sensor, and replace...
