Top failures
Coil spring fractured or broken 2.91%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Position lamp not working 1.58%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Tyre cut reaching ply or cords 1.58%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp aim set too high 1.36%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre tread below 1.6mm 1.3%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too low 1.24%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Common advisories
Tyre worn close to legal limit (11.42%) · Engine oil leak, not excessive (7.12%) · Brake disc pitted or scored (4.89%) · Brake pads wearing thin (4.86%) · Flexible brake hose slightly deteriorated (3.68%) · Suspension arm pin/bush showing wear (3.48%)
