The Bank 1 Sensor 2, is after catalytic converter; while, it does play a role in the computer adjusting the engine, the Bank 1 Sensor 1, plays a more important role. If you do decide to replace the 02 sensor; it is recommended to only use oem genuine Bosch sensors, which VW uses from the factory and are supplied, when buying genuine VW parts.
You can look up the correct sensor; by using the Bosch online catalog here:
