1989 Volkswagen Polo — MOT failures & pass rate
The 1989 Volkswagen Polo passed 71.4% of its 1,069 recorded MOT tests. That is 6.7 percentage points worse than superminis of a similar age, which fail at 21.9%. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (15.2%) and suspension (12.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, component mounting prescribed areas and non catalyst emissions — headlamp aim alone was recorded 98 times.
Condition tracks the odometer closely. Failures run at 17.5% in the 0-30k band and 28.7% in the 150k+ band, a 11.2-point spread.
Suspension is the most common advisory, noted on 30.5% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 32.6% in 2021 to 28.9% in 2025, as the worst-kept examples leave the fleet.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |

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 | 30.5% | 326 |
| 2 | Brakes | 29.4% | 314 |
| 3 | Body, structure & corrosion | 25.4% | 272 |
| 4 | Emissions & environmental | 20.2% | 216 |
| 5 | Tyres | 18.7% | 200 |
| 6 | Lighting & signalling | 11.8% | 126 |
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 | 40 | 17.5% |
| 30-60k | 253 | 27.3% |
| 60-90k | 371 | 31.0% |
| 90-120k | 222 | 28.4% |
| 120-150k | 102 | 27.5% |
| 150k+ | 80 | 28.7% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 267 | 32.6% |
| 2022 | 234 | 29.1% |
| 2023 | 177 | 22.6% |

What to check before buying a 1989 Polo
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 15.2% of tests. Start there.
- Lighting & signalling (15.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (12.4% 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 (11.2% 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.
