Top failures
Shock absorber bush excessively worn 3.86%
Worn shock absorber bushes cause knocking and poor ride control, and they tend to worsen, so they need replacing.
Wiper blade not clearing windscreen 2.3%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Rear fog lamp not working 2.28%
A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.
Diesel engine warning light faulty 1.59%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Brake pads worn below 1.5mm 1.57%
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 1.47%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Tyre worn close to legal limit (12.14%) · Wheel bearing slight play (9.51%) · Shock absorber bush slightly worn (5.17%) · Brake disc pitted or scored (4.73%) · Brake pads wearing thin (4.66%) · Anti-roll bar pin/bush showing wear (3.78%)
