Top failures
Coil spring fractured or broken 0.86%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Headlamp aim set too high 0.71%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre tread below 1.6mm 0.52%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Wiper blade not clearing windscreen 0.46%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Rigid brake pipe excessively corroded 0.46%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Engine warning light inoperative or lit 0.4%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
Brake disc pitted or scored (8.01%) · Tyre worn close to legal limit (6.71%) · Brake pipes corroded and greasy (6.04%) · Tyre slightly damaged or cracking (4.4%) · Engine oil leak, not excessive (1.85%) · Suspension arm pin/bush showing wear (1.69%)
