Top failures
Tyre tread below 1.6mm 1.34%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.22%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake pads worn below 1.5mm 0.71%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Lambda reading outside specified limits 0.57%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Coil spring fractured or broken 0.55%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 0.44%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (10.66%) · Brake disc pitted or scored (8.42%) · Tyre slightly damaged or cracking (7.03%) · Brake pads wearing thin (4.93%) · Suspension arm pin/bush showing wear (3.49%) · Child seat limits belt inspection (3.12%)
