Sounds like drive by wire is reporting an error. VCDS would shed more light, if it was intermittent or constant etc. If it drives ok I'm all for ignoring codes.

Reading posts on other forums it seems something about airflow meter related. Might take it apart and clean it up with some carb cleaner?
