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.
Similar thing happened to me. It was the oxygen sensor that went.
The cause of an exhaust indicator light in a Volkswagen Beetle is probably an oxygen sensor. There also a possibility that an exhaust pipe is plugged or there is a hole due to rust.

Oxygen Sensor is in the exhaust system. It measure the amount of chemicals in you exhaust and then tells the computer to either turn on the EGR or adjust the air/fuel mix. There will be 2 on the exhaust system. One before the catalytic converter and one after it.

It's integrated into the oxygen sensor. Buy a new oxygen sensor and you get a free oxygen sensor heater.
Remove the oxygen sensor vacuum to. Remove the oxygen sensor screws. Reverse the process to install the new oxygen sensor.
