Overview
Community orientation

Its 3.2 FSI (V6) and 3.0 TDI (V6) patterns are authored on this generation and resolve, through the shared engine graph, onto every later Audi that uses those engines. This is an editorial catalogue summary, not a reliability rating; the per-configuration community-orientation patterns are below, each with the build window it applies to.
