Top failures
Shock absorber bush excessively worn 3.78%
Worn shock absorber bushes cause knocking and poor ride control, and they tend to worsen, so they need replacing.
Wiper blade not clearing windscreen 2.06%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Rear fog lamp not working 1.21%
A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.
Brake pads worn below 1.5mm 1.14%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Anti-roll bar pin or bush excessively worn 1.05%
Worn anti-roll bar bushes cause knocking noises and reduce handling stability, so they should be replaced.
Registration plate lamp not working 1.03%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Common advisories
Tyre worn close to legal limit (9.17%) · Wheel bearing slight play (5.44%) · Shock absorber bush slightly worn (4.94%) · Brake pads wearing thin (3.75%) · Brake disc pitted or scored (2.85%) · Anti-roll bar pin/bush showing wear (2.46%)
