Top failures
Registration plate lamp not working 2.14%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Tyre cut reaching ply or cords 1.94%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Coil spring fractured or broken 1.37%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 1.31%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Brake pads worn below 1.5mm 1%
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 0.99%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Tyre worn close to legal limit (10.98%) · Tyre slightly damaged or cracking (9.15%) · Brake pads wearing thin (6.91%) · Brake disc pitted or scored (4.29%) · Brake discs showing some wear (2.73%) · Tyre has a shallow cut (2.4%)
