1997 Volvo V40 — MOT failures & pass rate
The 1997 Volvo V40 passed 67.7% of its 697 recorded MOT tests. Small family cars of a similar age fail 26.6% of the time, so this is 5.7pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 21.8% of tests against 13.8% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, headlamp aim and catalyst emissions — component mounting prescribed areas alone was recorded 83 times.
Mileage is the strongest signal on the record: 20.5% of 30-60k cars fail, rising to 41.2% once past 150k — 2.0× the risk.
Brakes is the most common advisory, noted on 36.7% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 33.9% in 2021 to 28.8% 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 | Brakes | 36.7% | 256 |
| 2 | Suspension | 32.0% | 223 |

| 5 | Body, structure & corrosion | 16.1% | 112 |
| 6 | Lighting & signalling | 14.5% | 101 |
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 | 83 | 20.5% |
| 60-90k | 139 | 28.1% |
| 90-120k | 217 | 35.0% |
| 120-150k | 157 | 35.7% |
| 150k+ | 85 | 41.2% |
Failure rate by age

What to check before buying a 1997 V40
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 21.8% of tests. Start there.
- Lighting & signalling (21.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (13.8% 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.
- Brakes (13.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
