The Audi TT 8N (1998–2006) spans the 1.8T 20v (EA113) four-cylinder in 150/180/225 states of tune and, from the 2003 facelift, the 3.2 VR6, as coupe and roadster, front-wheel drive or quattro all-wheel drive, with manual or the DSG dual-clutch. It authors no problems of its own: the 1.8T patterns are modelled on the generation that anchors that engine and resolve, through the shared engine graph, onto every 1.8T configuration. The 3.2 VR6 has no community patterns yet — a coverage gap, not a claim it has none. This is an editorial catalogue summary, not a reliability rating; per-configuration community-orientation patterns come from the owning corpus, each with the build window it applies to.
