Reliability, common problems and owner reviews for the Audi A3 8V S3 2.0 TFSI quattro (CJXC). Check this before you buy used.

The S3's high-output EA888 (CJXC, 300hp) is a strong, tuneable performance engine on the same robust Gen3 architecture — but treat it as a fast car: many were remapped, clutches/DSG and tyres are consumables, and hard use accelerates carbon and oil use. Standard and well-maintained examples are dependable; inspect for tuning/abuse and check the DSG. Buy on documented history.
