2011 Volvo S40 MOT pass rate: 62.9% (4,320 tests)
Is the 2011 S40 getting worse?
Pass rate of 2011-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 63.4% -6.7 vs same-age |
|
| 2024 | 63.5% -5.4 vs same-age |
|
| 2025 | 61.6% -6.9 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 2011 Volvo S40 reliable?
2011-registered examples passed 62.9% of their MOT tests (4,320 tests, 2023–2025), -6.3 points versus all UK cars registered in the same year. At roughly 15 years old with a median 104,275 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2011 S40?
The median tested example shows 104,275 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 2011 S40?
In this cohort petrols pass 70.2% of tests against 61.0% 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.
