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.

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.
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.

The A1 has several recurring minor electrical/trim faults reported by UK owners: electric windows that stick or stop responding, light housings (especially with the hot xenon headlights) that suffer heat damage, interior/door rattles, and a sunroof that intermittently fails or ma… Repairs typically run $50-$500. Severity: low.
