2018 Audi A1 1.4L Petrol · BT67 EDJ

The 1.4-litre TFSI petrol engine in this A1 is reasonably economical, with official figures of around 47-54 mpg combined depending on the exact variant. Real-world economy typically falls between 38-45 mpg, and insurance should sit in group 15-18 for this model, making it moderately affordable to insure for a premium supermini.

Road tax for a 2018 1.4 TFSI A1 is around £190 per year (depending on exact CO2). Annual maintenance costs are typically higher than for mainstream superminis — expect £300-£500 for routine servicing at a main dealer, or £200-£350 at an independent specialist. Brake pads, discs, and tyres tend to wear every 20,000-30,000 miles on this model.

The MOT record shows no specific defects, but the two consecutive failures demand a thorough physical inspection. Start with the suspension — the Audi A1's top MOT failure reasons across the model range include ball joint and coil spring issues, so check for knocking over bumps and uneven tyre wear. Also inspect the headlamps carefully, as headlamp failure is the third most common MOT issue for this model; ensure both units are clear, secure, and properly aligned.

Under the bonnet, examine the 1.4 TFSI engine for any signs of oil leaks, particularly around the timing chain cover and the turbo oil return pipe. Check the coolant level and look for staining around the water pump and thermostat housing — both are known weak points. Listen for any timing chain rattle on a cold start, and inspect the underside of the car for corrosion, especially around the rear axle and exhaust hangers, which can deteriorate on cars that have seen winter road salt.

Inside the car, test all electrical systems including the infotainment screen, climate control, electric windows, and central locking. The MMI system in 2018 A1s can occasionally develop faults. Check that the air conditioning blows cold, as regassing costs around £80-£120. Finally, verify the mileage on the dashboard matches the MOT records and service book entries exactly.
