The defect emerged in frontal testing
An internal FMVSS208 frontal crash test damaged the TT tank against a heat-shield bracket. Audi investigated tolerances/mountings through further tests and simulation. This documents possible tank damage in a front impact, beyond direct contact against the outer tank wall.

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.

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.
Identify any discovered fluid. A stain photo distinguishes neither fuel from other fluids nor leak location. If tank was replaced/area cleaned, retain initial records and identify surfaces no longer examinable.
Remedy versus separate tank repair
20BX fits a protective cap on the heat-shield bracket. This addresses the described contact; it does not repair an already damaged tank. Production bracket removal cannot independently become another procedure for an older car.

Separate cap installation, tank inspection and repair of a confirmed leak. A cap does not confirm tank inspection following a later crash. A tank invoice likewise does not establish the exact damaging contact.
Conclusion limits
20V-076 explicitly names third-generation TT and specified quattro versions. Similar photos cannot determine another car’s hidden deformation. Verify current applicability and actual protection individually.

Applicability to the individual vehicle
- Only specified Coupe/Roadster quattro; 2WD explicitly excluded.
- Crash testing supports the mechanism, not an individual VIN’s leak or geometry.
