Why quattro matters

The bracket was a common body part but had no function on quattro. Front-wheel-drive versions use a different tank and are explicitly excluded. Certain TT Coupe quattro/Roadster quattro MY2016–2019 have separate build ranges; production changes/factory remedy already distinguish some cars.

Applicability and the full analysis

What to inspect after front impact

Ask the technician to examine accessible tank/bracket condition, beyond front panels, under the procedure for this version. Record actual contact/deformation and leak-test results. Front damage alone does not prove this tank punctured.
