2023 Audi A1 — MOT failures & pass rate
The 2023 Audi A1 passed 95.3% of its 1,009 recorded MOT tests. That is effectively the same as superminis of a similar age (5.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.1%) and lighting & signalling (1.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and brake pads — headlamp aim alone was recorded 19 times.
Tyres is the most common advisory, noted on 12.7% of tests — work that passed today but is likely due soon.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |
|---|---|---|
| 1 | Headlamp aim | 19 |
| 2 | Tread depth | 16 |
| 3 | Brake pads | 11 |
| 4 | Washers | 5 |
| 5 | Wipers | 4 |

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 12.7% | 128 |
| 2 | Brakes | 6.2% | 63 |
| 3 | Other defects | 3.3% | 33 |
| 4 | Visibility | 1.4% | 14 |
| 5 | Road wheels | 0.5% | 5 |
| 6 | Suspension | 0.3% | 3 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 843 | 3.8% |
| 30-60k | 159 | 8.8% |
What to check before buying a 2023 A1
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.1% of tests. Start there.
- Tyres (3.1% 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.
- Lighting & signalling (1.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (0.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
