1997 Volvo 900 Series — MOT failures & pass rate
Across 4,947 MOT tests, the 1997 Volvo 900 Series recorded a 75.4% pass rate. All cars of a similar age fail at 25.1%, so the 1997 900 Series sits squarely on the average. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.1% of all tests — 4.5 points clear of brakes, so it is the first thing to check.
At component level the recurring items are catalyst emissions, exhaust system and component mounting prescribed areas — catalyst emissions alone was recorded 329 times.
Condition tracks the odometer closely. Failures run at 19.0% in the 30-60k band and 26.3% in the 150k+ band, a 7.3-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 30.2% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 30.2% | 1,496 |
| 2 | Brakes | 29.0% | 1,433 |
| 3 | Emissions & environmental | 22.9% | 1,133 |
| 4 | Tyres | 20.5% | 1,016 |
| 5 | Body, structure & corrosion | 20.5% | 1,016 |
| 6 | Lighting & signalling | 17.8% | 882 |
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 | 116 | 19.0% |
| 60-90k | 350 | 18.9% |
| 90-120k | 716 | 22.6% |
| 120-150k | 1,140 | 24.5% |
| 150k+ | 2,611 | 26.3% |

What to check before buying a 1997 900 Series
On a 1997 900 Series, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.1% of tests. Check these areas before you commit.
- Lighting & signalling (14.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.7% 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.
- Body, structure & corrosion (8.2% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
