Average for cars of the same age and mileage
Top failures
Position lamp not working 2.09%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Lambda reading outside specified limits 1.69%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
CV joint boot split or insecure 1.63%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Rigid brake pipe excessively corroded 1.18%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Wiper blade not clearing windscreen 1.11%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Brake pipes corroded and greasy (11.66%) · Tyre worn close to legal limit (7.48%) · Brake disc pitted or scored (7.23%) · Engine oil leak, not excessive (6.16%) · Tyre slightly damaged or cracking (3.56%) · Exhaust has minor gas leak (1.82%)
