Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.09%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 0.77%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Coil spring fractured or broken 0.67%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Lambda reading outside specified limits 0.64%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Headlamp aim set too low 0.64%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre cut reaching ply or cords 0.58%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre worn close to legal limit (8.1%) · Brake pads wearing thin (5.12%) · Brake disc pitted or scored (4.16%) · Tyre slightly damaged or cracking (2.02%) · Engine oil leak, not excessive (1.7%) · Nail in tyre, monitor (1.47%)
