Reliability, common problems and owner reviews for the Audi A4 B9 1.4 / 2.0 TFSI (EA888 Gen3). Check this before you buy used.
The petrols — the economical 1.4 TFSI (EA211) and the volume 2.0 TFSI (EA888 Gen3, shared with the A5/Q5/Passat) — make the B9 A4 refined and quick. Gen3 EA888 is much improved over the oil-burning Gen2: chain-driven, robust, with the usual modern cautions — occasional chain-tensioner attention, PCV faults, direct-injection carbon and water-pump items, plus the S tronic dual-clutch (where fitted) wanting fluid discipline. The 2.0 TFSI's later 'B-cycle' (Miller) versions are efficient and well-regarded. A documented car with a healthy chain is dependable. Buy on oil and gearbox history.
