Top failures
Position lamp not working 3.56%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Headlamp aim set too high 1.94%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Dipped beam headlamp not working 1.94%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Engine warning light inoperative or lit 1.9%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Wiper blade not clearing windscreen 1.77%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Direction indicator not working 1.73%
A failed indicator hides your turns from other road users, which is dangerous and must be repaired before driving.
Common advisories
Tyre worn close to legal limit (12.64%) · Brake disc pitted or scored (8.77%) · Suspension arm showing corrosion (5.92%) · Brake pads wearing thin (5.59%) · Sub-frame showing corrosion (5.27%) · Engine oil leak, not excessive (4.39%)
