Overview
Community orientation
The Audi A6 C7 (2011–2018) spans the 2.0 TFSI and 2.0 TDI four-cylinders and the 3.0 TFSI supercharged and 3.0 TDI V6 quattro units, as sedan and Avant, front- or quattro all-wheel drive. Its 3.0 TFSI (EA837) patterns are authored on this generation and resolve, through the shared engine graph, onto every later Audi that uses that engine; the 2.0 TFSI, 2.0 TDI and 3.0 TDI patterns are owned by other corpora. 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.
