2012 Volkswagen Polo — MOT failures & pass rate
236,808 MOT tests on the 2012 Volkswagen Polo are in this dataset, and 77.9% of them passed. That is effectively the same as superminis of a similar age (22.7% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 13.6% of tests against 9.4% for the next-worst category.
At component level the recurring items are headlamp aim, headlamp and shock absorbers — headlamp aim alone was recorded 13,287 times.
Mileage is the strongest signal on the record: 10.5% of 0-30k cars fail, rising to 28.7% once past 150k — 2.7× the risk.
The petrol cars hold up better: 21.6% fail against 25.9% for diesel, a 4.3-point gap across 236,798 tests.
Tyres is the most common advisory, noted on 27.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 19.7% of tests failed in 2021 against 24.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 Polo
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 13.6% of tests. Start there.
- Lighting & signalling (13.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.4% 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.
- Brakes (7.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
