2020 Volkswagen Polo — MOT failures & pass rate
Across 86,131 MOT tests, the 2020 Volkswagen Polo recorded a 92.2% pass rate. Against superminis of a similar age (8.9% fail rate), the 2020 Polo comes out 1.0pp better. Failures cluster in visibility, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — visibility (4.2%) and tyres (3.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and washers — wipers alone was recorded 3,205 times.
Mileage is the strongest signal on the record: 5.9% of 0-30k cars fail, rising to 18.7% once past 90-120k — 3.2× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 19.7% of tests without failing them.
The trend is improving — the fail rate fell from 19.1% in 2021 to 9.4% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2020 Polo
On a 2020 Polo, visibility is what the MOT record says goes wrong most — it appeared in 4.2% of tests. Check these areas before you commit.
- Visibility (4.2% 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.
- Tyres (3.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (1.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
