Top failures
Rigid brake pipe excessively corroded 2.3%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre tread below 1.6mm 2.3%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Position lamp not working 1.63%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Shock absorber serious fluid leak 1.25%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Tyre cut reaching ply or cords 0.96%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Rear fog lamp not working 0.86%
A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.
Common advisories
Tyre worn close to legal limit (13.12%) · Brake pipes corroded and greasy (8.52%) · Engine oil leak, not excessive (8.52%) · Brake disc pitted or scored (5.46%) · Brake pads wearing thin (4.98%) · Shock absorber light oil misting (3.64%)
