Reliability, common problems and owner reviews for the Audi A3 8Y 30 / 35 TFSI (1.0 / 1.5 EA211 EVO). Check this before you buy used.

The TSI petrols — the 1.0 three-cylinder and the 1.5 four (EA211 EVO, with ACT cylinder-deactivation, and the eTSI 48V mild-hybrid — shared across the Octavia IV/Leon IV/Audi A3) — are economical, willing and belt-driven, far more robust than VAG's old chain-driven small TSIs. Cautions are the modern norm: cam-belt service (keep to schedule), direct-injection intake carbon over time, water-pump/PCV items, the early 1.5 EVO/eTSI low-load hesitation and software niggles (the Mk8's early software was famously buggy — ensure updates), and the 7-speed DSG on eTSI. A serviced, updated car is a genuinely good engine. Buy on belt and software history.
