1993 Volvo 800 Series — MOT failures & pass rate
Across 394 MOT tests, the 1993 Volvo 800 Series recorded a 76.4% pass rate. That is effectively the same as all cars of a similar age (23.4% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (12.2%) and brakes (10.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, service brake performance and joints — wipers alone was recorded 30 times.
Mileage is the strongest signal on the record: 13.4% of 60-90k cars fail, rising to 23.7% once past 150k.
Suspension is the most common advisory, noted on 32.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 20.8% of tests failed in 2021 against 22.9% in 2025, the usual pattern as a fleet ages.

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 | 32.2% | 127 |
| 2 | Brakes | 26.7% | 105 |
| 3 | Tyres | 23.6% | 93 |
| 4 | Emissions & environmental | 18.5% | 73 |
| 5 | Body, structure & corrosion | 18.5% | 73 |
| 6 | Other defects | 17.5% | 69 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 67 | 13.4% |
| 90-120k | 112 | 26.8% |
| 120-150k | 73 | 30.1% |
| 150k+ | 114 | 23.7% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 96 | 20.8% |
| 2022 | 87 | 25.3% |
| 2023 | 73 | 20.5% |
| 2024 | 77 | 28.6% |

What to check before buying a 1993 800 Series
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 12.2% of tests. Start there.
- Lighting & signalling (12.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (10.4% 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.
- Visibility (8.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
