Top failures
Headlamp aim set too high 0.72%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Wiper blade not clearing windscreen 0.72%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Rigid brake pipe excessively corroded 0.68%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre tread below 1.6mm 0.59%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Coil spring fractured or broken 0.54%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 0.54%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Brake disc pitted or scored (6.06%) · Tyre worn close to legal limit (5.52%) · Brake pipes corroded and greasy (4.21%) · Tyre slightly damaged or cracking (3.12%) · Suspension ball joint slight play (1.99%) · Engine oil leak, not excessive (0.95%)
