Overview
Community orientation
The Audi A4 B7 (2004–2008) spans the 1.8T and 2.0 TFSI petrol fours, the 3.2 FSI V6, and the 1.9 TDI, 2.0 TDI and 3.0 TDI V6 diesels, as sedan and Avant, front- or quattro all-wheel drive. B7 authors no problems of its own: each engine's community-orientation patterns are owned by another Audi generation and resolve, through the shared engine graph, onto B7's applications. This is an editorial catalogue summary, not a reliability rating; verify any engine-level pattern against the owning corpus and a manufacturer document before relying on it.
