The Audi A3 8P (2003–2013) is modelled here with the 2.0T FSI/TFSI petrol four (EA113, incl. the S3 2.0 TFSI quattro) and the 1.9 TDI and 2.0 TDI diesels, as 3-door hatchback and 5-door Sportback, front- or quattro all-wheel drive. The 8P's 1.4 TFSI (EA111) and facelift-era 1.8 TFSI (EA888) are not yet in the shared engine registry, so they are not modelled — a coverage gap, not a claim they didn't exist. A3 8P 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 A3 8P'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.

Pre-purchase checklist

- ☐Road-test under load and watch for boost surge, power loss or limp mode
