Top failures
Wiper blade not clearing windscreen 1.95%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp aim set too high 0.85%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Brake pads worn below 1.5mm 0.65%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre tread below 1.6mm 0.65%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.52%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Windscreen washers not working 0.13%
Without working washers the windscreen cannot be cleaned while driving, which is a safety risk in dirty weather.
Common advisories
Tyre worn close to legal limit (8%) · Brake pads wearing thin (2.47%) · Tyre slightly damaged or cracking (1.95%) · Brake disc pitted or scored (1.69%) · Tyre worn close to legal limit (1.37%) · Nail in tyre, monitor (1.24%)
