Top failures
Tyre cut reaching ply or cords 1.47%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 1.44%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.01%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Windscreen washer fluid insufficient 0.63%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Shock absorber serious fluid leak 0.53%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Headlamp aim set too low 0.51%
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 (7.89%) · Shock absorber light oil misting (4.25%) · Tyre slightly damaged or cracking (3.84%) · Nail in tyre, monitor (1.62%) · Brake pads wearing thin (1.54%) · Tyre has a shallow cut (1.49%)
