Top failures
Tyre cut reaching ply or cords 1.16%
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 0.76%
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 0.69%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Number plate does not meet standards 0.65%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Diesel engine warning light faulty 0.43%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Windscreen washer fluid insufficient 0.4%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (7.19%) · Brake disc pitted or scored (4.62%) · Brake pads wearing thin (4.62%) · Nail in tyre, monitor (2.13%) · Tyre worn close to legal limit (1.95%) · Suspension arm pin/bush showing wear (1.77%)
