Top failures
Coil spring fractured or broken 6.37%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Diesel engine warning light faulty 2.57%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre tread below 1.6mm 2.25%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.79%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Windscreen washer fluid insufficient 1.49%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre cut reaching ply or cords 1.32%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre worn close to legal limit (12.68%) · Brake disc pitted or scored (4.93%) · Tyre slightly damaged or cracking (4.45%) · Brake pads wearing thin (3.05%) · Brake discs showing some wear (2.33%) · Suspension arm pin/bush showing wear (2%)
