2003 MINI Cooper — MOT failures & pass rate
2,736 MOT tests on the 2003 MINI Cooper are in this dataset, and 70.0% of them passed. That is effectively the same as superminis of a similar age (29.4% 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 19.9% of tests against 12.9% for the next-worst category.
At component level the recurring items are headlamp aim, rigid brake pipes and joints — headlamp aim alone was recorded 435 times.
Condition tracks the odometer closely. Failures run at 16.7% in the 0-30k band and 36.3% in the 150k+ band, a 19.6-point spread — more than double.
Brakes is the most common advisory, noted on 46.4% 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 | 46.4% | 1,268 |
| 2 | Suspension | 33.6% | 919 |
| 3 | Emissions & environmental | 29.6% | 809 |
| 4 | Tyres | 26.1% | 714 |
| 5 | Lighting & signalling | 19.9% | 543 |
| 6 | Body, structure & corrosion | 15.7% | 429 |
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 | 66 | 16.7% |
| 30-60k | 259 | 23.2% |
| 60-90k | 618 | 27.7% |
| 90-120k | 983 | 32.7% |
| 120-150k | 626 | 30.5% |
| 150k+ | 182 | 36.3% |
Failure rate by age

What to check before buying a 2003 Cooper
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.9% of tests. Start there.
- Lighting & signalling (19.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.9% 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 (10.8% 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.
