2014 BMW 3 — MOT failures & pass rate
278 MOT tests on the 2014 BMW 3 are in this dataset, and 86.3% of them passed. That is 4.6 percentage points better than all cars of a similar age, which fail at 18.2%. Failures cluster in tyres, lighting & signalling and suspension.
What the MOT record shows
One area stands out: tyres, recorded in 8.3% of tests against 2.9% for the next-worst category.
At component level the recurring items are tread depth, shock absorbers and brake discs — tread depth alone was recorded 9 times.
Mileage matters less than usual here: the 2014 3 fails 12.9% of the time in the 30-60k band and 11.9% at 90-120k, a spread of only 1.0 points.
Tyres is the most common advisory, noted on 21.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 16.1% in 2021 to 12.0% in 2025, as the worst-kept examples leave the fleet.

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 | 21.2% | 59 |
| 2 | Brakes | 15.1% | 42 |

| 6 | Visibility | 2.2% | 6 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 101 | 12.9% |
| 60-90k | 117 | 15.4% |
| 90-120k | 42 | 11.9% |
Failure rate by age
Trend over time

What to check before buying a 2014 3
The failure pattern for this year is specific enough to inspect against: tyres accounted for 8.3% of tests. Start there.
- Tyres (8.3% 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 (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (2.2% 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.
