Top failures
Rigid brake pipe excessively corroded 1.02%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Headlamp aim set too high 0.48%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Wiper blade not clearing windscreen 0.48%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Lambda reading outside specified limits 0.41%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Suspension ball joint excessively worn 0.41%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Tyre tread below 1.6mm 0.41%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Tyre worn close to legal limit (6.19%) · Brake disc pitted or scored (6.12%) · Brake pipes corroded and greasy (4.83%) · Tyre slightly damaged or cracking (4.76%) · Suspension ball joint slight play (1.97%) · Suspension arm pin/bush showing wear (0.95%)
