Top failures
Tyre tread below 1.6mm 1.73%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.62%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Engine warning light inoperative or lit 0.62%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Headlamp aim set too high 0.4%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Diesel engine warning light faulty 0.4%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Brake pads worn below 1.5mm 0.31%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Common advisories
Tyre worn close to legal limit (7.26%) · Brake pads wearing thin (3.19%) · Tyre slightly damaged or cracking (1.06%) · Child seat limits belt inspection (1.02%) · Nail in tyre, monitor (0.93%) · Tyre worn close to legal limit (0.93%)
