Average for cars of the same age and mileage
Top failures
Position lamp not working 3.27%
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 2.34%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Coil spring fractured or broken 1.77%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Rigid brake pipe excessively corroded 1.6%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Headlamp aim set too high 1.3%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Wiper blade not clearing windscreen 1.18%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Common advisories
Brake pipes corroded and greasy (11.75%) · Brake disc pitted or scored (9.68%) · Tyre worn close to legal limit (7.23%) · Slight play in steering rack joints (5.02%) · Tyre slightly damaged or cracking (4.92%) · Engine oil leak, not excessive (3.49%)
