2005 MINI Cooper — MOT failures & pass rate
Across 4,429 MOT tests, the 2005 MINI Cooper recorded a 71.5% pass rate. That is effectively the same as superminis of a similar age (29.0% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.7% of tests against 11.4% for the next-worst category.
At component level the recurring items are rigid brake pipes, headlamp aim and pins and bushes — rigid brake pipes alone was recorded 367 times.
Condition tracks the odometer closely. Failures run at 14.3% in the 0-30k band and 30.2% in the 150k+ band, a 15.9-point spread — more than double.
Brakes is the most common advisory, noted on 47.8% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 47.8% | 2,116 |
| 2 | Emissions & environmental | 33.3% | 1,476 |
| 3 | Suspension | 31.4% | 1,389 |

| 5 | Lighting & signalling | 17.5% | 774 |
| 6 | Body, structure & corrosion | 14.5% | 644 |
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 | 105 | 14.3% |
| 30-60k | 530 | 22.1% |
| 60-90k | 1,378 | 26.9% |
| 90-120k | 1,634 | 31.0% |
| 120-150k | 653 | 32.6% |
| 150k+ | 129 | 30.2% |
Failure rate by age

What to check before buying a 2005 Cooper
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.7% of tests. Start there.
- Lighting & signalling (14.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Suspension (10.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
