Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 2.8%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 2.12%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Suspension arm pin/bush excessively worn 1.92%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Position lamp not working 1.35%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Wiper blade not clearing windscreen 1%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp aim set too low 0.62%
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 (12.65%) · Brake pads wearing thin (9.35%) · Brake disc pitted or scored (6.57%) · Child seat limits belt inspection (2.45%) · Tyre slightly damaged or cracking (2.32%) · Tyre worn close to legal limit (2.1%)
