Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 4.19%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Dipped beam headlamp not working 3.65%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Brake pads worn below 1.5mm 3.31%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Rigid brake pipe excessively corroded 3.11%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Position lamp not working 2.5%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Tyre pressure monitoring system faulty 2.3%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Common advisories
Tyre worn close to legal limit (19.88%) · Brake pipes corroded and greasy (12.58%) · Brake disc pitted or scored (12.24%) · Brake pads wearing thin (11.63%) · Coil spring showing some corrosion (7.1%) · Tyre slightly damaged or cracking (5.34%)
