1997 Volkswagen Polo — MOT failures & pass rate
The 1997 Volkswagen Polo passed 72.1% of its 3,375 recorded MOT tests. That is 1.2 percentage points better than superminis of a similar age, which fail at 29.1%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (11.5%) and suspension (11.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, component mounting prescribed areas and prescribed areas — catalyst emissions alone was recorded 312 times.
Mileage is the strongest signal on the record: 17.9% of 0-30k cars fail, rising to 32.6% once past 150k.
Advisories point at the next bill rather than this one: suspension was flagged on 37.8% of tests without failing them.
The trend is improving — the fail rate fell from 27.4% in 2021 to 25.5% in 2025, as the worst-kept examples leave the fleet.

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 | 37.8% | 1,275 |
| 2 | Brakes | 29.7% | 1,001 |

| 5 | Body, structure & corrosion | 17.8% | 601 |
| 6 | Other defects | 14.5% | 489 |
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 | 190 | 17.9% |
| 30-60k | 1,035 | 23.3% |
| 60-90k | 1,159 | 28.2% |
| 90-120k | 600 | 33.8% |
| 120-150k | 271 | 34.7% |
| 150k+ | 98 | 32.6% |
Failure rate by age

What to check before buying a 1997 Polo
On a 1997 Polo, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.5% of tests. Check these areas before you commit.
- Lighting & signalling (11.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.5% 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.
- Brakes (9.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
