2018 BMW M2 — MOT failures & pass rate
The 2018 BMW M2 passed 91.2% of its 7,331 recorded MOT tests. That is effectively the same as coupes & convertibles of a similar age (9.0% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.2%) and suspension (2.4%) 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 registration plates — coil spring alone was recorded 172 times.
Condition tracks the odometer closely. Failures run at 7.1% in the 0-30k band and 14.3% in the 60-90k band, a 7.2-point spread — more than double.
Tyres is the most common advisory, noted on 16.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 7.1% of tests failed in 2021 against 10.3% in 2025, the usual pattern as a fleet ages.

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 | 16.1% | 1,183 |
| 2 | Brakes | 3.9% | 289 |
| 3 | Other defects | 3.9% | 285 |
| 4 | Visibility | 2.1% | 154 |
| 5 | Suspension | 1.1% | 77 |
| 6 | Emissions & environmental | 0.6% | 45 |
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 | 3,559 | 7.1% |
| 30-60k | 3,306 | 9.7% |
| 60-90k | 441 | 14.3% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2022 | 1,468 | 7.1% |
| 2023 | 1,426 | 9.2% |

What to check before buying a 2018 M2
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.2% of tests. Start there.
- Tyres (4.2% 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.
- Suspension (2.4% 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 (2.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
