Top failures
Wiper blade not clearing windscreen 2.62%
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 2.52%
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 1.66%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.48%
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 1.46%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Headlamp aim set too low 1.36%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Common advisories
Tyre worn close to legal limit (13.79%) · Brake pads wearing thin (10.72%) · Tyre slightly damaged or cracking (8.18%) · Brake disc pitted or scored (6.01%) · Brake discs showing some wear (2.06%) · Child seat limits belt inspection (1.96%)
