The 2018 Audi A1 passes its MOT significantly better than the UK average, with an 88.1% first-time pass rate compared to 80%, though the concerning figure here is that nearly a quarter (24.1%) of these cars have recorded a dangerous defect at some point—a warning sign for potential buyers to get any used example inspected thoroughly. Petrol versions perform fractionally better at 88.2% versus diesel at 85.9%, but both are well above average.

At around 31,600 miles median, these cars are running relatively light for their age, which partly explains the strong pass rate—yet the average car still racks up 5.7 advisories per test, suggesting wear items like brakes and suspension need watching as mileage builds. Prospective buyers should budget for incremental maintenance, but mechanically this is a solid performer; your main priority is a pre-purchase inspection that specifically checks the history for any previous dangerous defect flags.

The 2018 Audi A1 passes its MOT first time at roughly the UK average rate (88.9%) — solid but worth checking this vehicle's history carefully.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 88.9% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 5.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 19,825 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

Brake wear 23.4%
Rear Brake disc worn, pitted or scored, but not seriously weakened · Rear Brake pad(s) wearing thin · Offside Rear Brake disc worn, pitted or scored, but not seriously weakened · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 10.6%
Nearside Front Suspension arm pin or bush worn but not resulting in excessive movement
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
