Top failures
Wiper blade not clearing windscreen 3.56%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Brake pads worn below 1.5mm 2.19%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre tread below 1.6mm 1.44%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.69%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Dipped beam headlamp not working 0.5%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Windscreen washer fluid insufficient 0.49%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (12.92%) · Brake pads wearing thin (10.51%) · Brake disc pitted or scored (5.62%) · Tyre slightly damaged or cracking (3.18%) · Child seat limits belt inspection (2.53%) · Brake discs showing some wear (2.48%)
