What is the 2010-2014 Audi A1 1.2 / 1.4 TFSI (EA111) Timing Chain Stretch and Tensioner Failure?
Early Audi A1 8X petrol cars fitted with the EA111 1.2 TFSI (CBZA/CBZB) and 1.4 TFSI (CAXA/CTHE/CAVG) engines suffer from a weak timing chain tensioner that loses hydraulic pressure, allowing the chain to go slack and stretch. Combined with worn plastic chain guides, the camshaft… Repairs typically run $700-$1,800. Severity: high.
What is the 2010-2016 Audi A1 1.4 TFSI Turbocharger Failure?
The turbocharger on the 1.4 TFSI petrol A1 is a recognised weak point. The turbine/centre housing and bearings can fail, often aggravated by the engine's oil-consumption tendencies (oil starvation/coking of the turbo bearing). When it fails it produces a notable loss of power and… Repairs typically run $800-$2,500. Severity: high.
What is the 2011-2016 Audi A1 7-Speed S tronic (DQ200 / 0AM) Dual-Clutch Mechatronic Failure?
A1s fitted with the 7-speed dry-clutch S tronic (DQ200, VAG code 0AM) automatic suffer mechatronic (valve body / hydraulic control unit) failures. A design flaw in the valve body's accumulator/canister wall can crack and lose high hydraulic pressure, while the dry clutch packs we… Repairs typically run $1,200-$2,800. Severity: high.
What is the 2010-2015 Audi A1 Excessive Oil Consumption on 1.2 / 1.4 TFSI (EA111) Engines?
The early EA111 TFSI engines in the A1 are known to consume oil at an abnormal rate — owners report figures around 0.5 to 1.0 litre per 1,000 km. The root cause is the piston ring design (particularly the oil-control/scraper rings) which allows oil past the pistons into the combu… Repairs typically run $300-$4,000. Severity: high.
What is the 2010-2018 Audi A1 1.6 / 2.0 TDI Diesel DPF Clogging and EGR Valve Faults?
The A1 is sold mainly as a town/city car, so diesel (1.6 TDI / 2.0 TDI) owners doing short, stop-start journeys never get the diesel particulate filter hot enough for passive regeneration. The DPF clogs with soot, and a faulty/sticking EGR valve accelerates this by raising soot o… Repairs typically run $200-$1,500. Severity: medium.
What is the 2010-2018 Audi A1 TFSI Direct-Injection Carbon Build-Up on Intake Valves?
Because the TFSI engines (1.2/1.4 EA111 and EA211) inject fuel directly into the cylinder, no fuel washes over the intake valves. Oil vapour from the crankcase ventilation bakes onto the hot valves and intake ports over time, restricting airflow and causing misfires, rough idle a… Repairs typically run $300-$1,000. Severity: medium.
