2011 Audi A1 1.4L Petrol · X28 NAK

The 1.4-litre petrol A1 typically returns around 45-50 mpg in real-world driving, with insurance usually sitting in group 14-18 depending on trim and specification, making it moderately priced to insure for a premium hatchback. Annual VED for a 2011 petrol of this engine size is in the lower band and inexpensive to tax. Routine maintenance such as brake discs and pads, tyres, and minor servicing tends to be Audi-priced rather than economy, so budget around £300-500 for a standard service and allow extra for items like coil packs and cam chain tensioners if due.

For an overall estimate covering fuel, tax, insurance and typical maintenance, this A1 is likely to cost in the region of £1,400-£1,800 per year assuming moderate mileage. Higher annual mileages will push fuel costs up but servicing is fixed; lower mileages with lots of short journeys could increase wear on the turbo and oil system.

The aggregate MOT data for the Audi A1 highlights anti-roll bar ball joints, headlamp issues and further ball joint wear as the most common failure reasons, so these deserve priority during inspection. On X28NAK specifically, the 2022 advisory on the offside front anti-roll bar ball joint dust cover warrants a close check of the entire front anti-roll bar setup — look for perished boots, excess play in the joints, and any oily residue around the dampers which could indicate shock absorber seal failure. The 2025 tyre advisory suggests examining the nearside front wheel alignment and inspecting all four tyres for uneven wear patterns that could point to worn suspension bushes or wishbone issues.

Beyond MOT-linked items, a 15-year-old A1 should be inspected for corrosion around the rear arches and sills, proper operation of the turbocharger (listen for whine and check for boost delivery), condition of the dual-clutch automatic if so equipped, and the health of the in-car electronics including MMI functions where fitted. Verify the timing chain has been replaced or at least inspected, as the 1.4 TFSI EA111 engine is known to stretch chains at high mileages, and confirm coolant and brake fluid are fresh.
