Overview
Community orientation
The Audi A4 B6 (2000–2004) spans the 1.8T turbo four, the 2.4/3.0L V6 30v, and the 1.9 TDI and late-run 2.0 TDI diesels, as sedan and Avant, front- or quattro all-wheel drive. This generation authors no engine patterns of its own: each engine's community-orientation patterns are authored on its owner corpus and resolve, through the shared engine graph, onto B6's configurations. This is an editorial catalogue summary, not a reliability rating; the per-configuration patterns are shown with the build window each applies to.
