If that's the only code, it's likely the primary O2 sensor (before the catalytic converter). That's the one that determines the fuel mixture.

As it says just one bank I would suspect possibly an injector or lambda. In Vagcom you can do a lambda load test, I suggest you do this as it individually does each lambda sensor to check it.
Check your injectors as well.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using Fixya, and have a nice day.
