Top failures
Dipped beam headlamp not working 2.66%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Tyre tread below 1.6mm 1.81%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 1.73%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Brake discs significantly worn 1.43%
Heavily worn discs reduce braking performance and wear pads faster, so a replacement will soon be needed.
Tyre pressure monitoring system faulty 1.37%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Main beam headlamp not working 1.25%
A failed main beam reduces night-time visibility on unlit roads, so the headlamp should be repaired promptly.
Common advisories
Brake disc pitted or scored (17.37%) · Tyre worn close to legal limit (16.15%) · Brake pads wearing thin (6.17%) · Tyre slightly damaged or cracking (4.87%) · Child seat limits belt inspection (2.96%) · Nail in tyre, monitor (2.52%)
