2015 BMW 125 MOT pass rate: 84.3% (2,633 tests)
Is the 2015 125 getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.4% +2.8 vs same-age |
|
| 2024 | 85.4% +6.8 vs same-age |
|
| 2025 | 84.2% +7.2 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs
Is a 2015 BMW 125 reliable?
2015-registered examples passed 84.3% of their MOT tests (2,633 tests, 2023–2025), +5.6 points versus all UK cars registered in the same year. At roughly 11 years old with a median 76,824 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2015 125?
The median tested example shows 76,824 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
Should I buy the petrol or diesel 2015 125?
In this cohort petrols pass 86.7% of tests against 83.5% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
