Top failures
Headlamp aim set too low 1.16%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Wiper blade not clearing windscreen 1.09%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Brake pads worn below 1.5mm 1.09%
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 1.09%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Diesel engine warning light faulty 1.02%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Headlamp aim set too high 0.95%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (10.69%) · Brake pads wearing thin (4.36%) · Shock absorber bush slightly worn (2.04%) · Brake discs showing some wear (1.36%) · Brake disc pitted or scored (1.16%) · Slight play in steering rack joints (0.95%)
