2012 Audi A1 — MOT failures & pass rate
114,912 MOT tests on the 2012 Audi A1 are in this dataset, and 79.5% of them passed. Against superminis of a similar age (22.7% fail rate), the 2012 A1 comes out 2.2pp better. Failures cluster in suspension, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — suspension (9.0%) and lighting & signalling (7.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, headlamp aim and pins and bushes — coil spring alone was recorded 4,785 times.
Mileage is the strongest signal on the record: 10.5% of 0-30k cars fail, rising to 25.2% once past 150k — 2.4× the risk.
The petrol cars hold up better: 19.1% fail against 22.1% for diesel, a 3.0-point gap across 114,910 tests.
Tyres is the most common advisory, noted on 28.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 18.1% of tests failed in 2021 against 22.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 A1
The failure pattern for this year is specific enough to inspect against: suspension accounted for 9.0% of tests. Start there.
- Suspension (9.0% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (7.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (6.8% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
