1989 Volvo 300 Series — MOT failures & pass rate
The 1989 Volvo 300 Series passed 75.8% of its 352 recorded MOT tests. Against all cars of a similar age (21.3% fail rate), the 1989 300 Series comes out 2.8pp worse. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (13.1%) and lighting & signalling (13.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, service brake performance and non catalyst emissions — component mounting prescribed areas alone was recorded 46 times.
Condition tracks the odometer closely. Failures run at 20.0% in the 0-30k band and 27.6% in the 90-120k band, a 7.6-point spread.
Suspension is the most common advisory, noted on 23.9% of tests — work that passed today but is likely due soon.

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 | 23.9% | 84 |
| 2 | Brakes | 23.0% | 81 |
| 3 | Tyres | 20.2% | 71 |

| 5 | Emissions & environmental | 13.4% | 47 |
| 6 | Lighting & signalling | 6.8% | 24 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 55 | 20.0% |
| 30-60k | 93 | 16.1% |
| 60-90k | 121 | 30.6% |
| 90-120k | 58 | 27.6% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1989 300 Series
The failure pattern for this year is specific enough to inspect against: brakes accounted for 13.1% of tests. Start there.
- Brakes (13.1% 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.
- Lighting & signalling (13.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.8% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
