Average for cars of the same age and mileage
Top MOT failures
- 1
Position lamp not working 3.13% of tests
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
- 2
Wiper blade not clearing windscreen 1.51% of tests
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
- 3
Tyre tread below 1.6mm 1.24% of tests
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
- 4
Brake pads worn below 1.5mm 1.21% of tests
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
- 5
Tyre cut reaching ply or cords 1.03% of tests
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
- 6
Anti-roll bar linkage dust cover unsealed 0.87% of tests
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
- 7
Tyre ply or cords exposed 0.85% of tests
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
- 8
Engine warning light inoperative or lit 0.8% of tests
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
