2018 Audi A3 2.0L Petrol · MM18 AAY

The 2.0-litre TFSI petrol in this Audi A3 typically returns 40-50 mpg on a motorway cruise but closer to 30-35 mpg in mixed use, giving an annual fuel bill of around £1,800-£2,200 at current prices for 12,000 miles. Road tax on a 2018 2.0-litre petrol A3 sits in the £170-£180 per year band, and insurance is likely group 20-25, costing roughly £500-£700 annually depending on the driver's record.

Maintenance is where this car could bite: the brake and tyre work suggested by the 2025 MOT, plus suspension components flagged in the aggregate top failure reasons, point to an annual servicing and repair bill of around £500-£800 once you factor in wear items. Realistically, total annual running costs including fuel, tax, insurance, and maintenance will come to roughly £3,000-£3,400, which is typical for a sporty German hatchback of this age.

The 2026 MOT failure on the offside front upper anti-roll bar ball joint dust cover is the priority inspection point. Have the anti-roll bar drop links, bushes, and ball joints across both axles physically checked, as the aggregate data shows anti-roll bar issues are the single most common MOT failure reason on this model.

The June 2025 failure mentioned 'brake performance unable to be tested' alongside all four tyres being below limit. Check the brake discs for lipping and the pads for remaining thickness, as a garage refusing to test brakes often signals seized calipers, contaminated pads, or a faulty parking brake mechanism. Verify tyre brand, age (DOT date code), and remaining tread on all four corners, as the previous owner clearly let all tyres wear down together, which can point to neglected maintenance habits.

Finally, this 2.0-litre petrol should be inspected for oil consumption (a known TFSI trait), timing chain noise on cold start, and DSG or manual gearbox oil condition depending on transmission. Coolant leaks from the water pump and thermostat housing are also worth a visual check.
