1986 Volkswagen Polo — MOT failures & pass rate
The 1986 Volkswagen Polo passed 74.4% of its 351 recorded MOT tests. Against superminis of a similar age (19.7% fail rate), the 1986 Polo comes out 5.9pp worse. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 19.9% of all tests — 9.7 points clear of suspension, so it is the first thing to check.
At component level the recurring items are non catalyst emissions, headlamp aim and component mounting prescribed areas — non catalyst emissions alone was recorded 26 times.
Condition tracks the odometer closely. Failures run at 26.0% in the 30-60k band and 20.0% in the 90-120k band, a 6.0-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 31.1% 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 | 31.1% | 109 |
| 2 | Brakes | 29.1% | 102 |
| 3 | Body, structure & corrosion | 23.1% | 81 |
| 4 | Emissions & environmental | 21.4% | 75 |
| 5 | Tyres | 15.4% | 54 |
| 6 | Other defects | 11.1% | 39 |
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 | 96 | 26.0% |
| 60-90k | 136 | 30.1% |
| 90-120k | 60 | 20.0% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 70 | 24.3% |
| 2022 | 82 | 25.6% |
| 2023 | 77 | 27.3% |

What to check before buying a 1986 Polo
On a 1986 Polo, lighting & signalling is what the MOT record says goes wrong most — it appeared in 19.9% of tests. Check these areas before you commit.
- Lighting & signalling (19.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.3% 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.
- Body, structure & corrosion (9.4% 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.
