Top failures
Position lamp not working 4.3%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Stop lamp not working 4.23%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Coil spring fractured or broken 4.01%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Rigid brake pipe excessively corroded 2.61%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Flexible brake hose excessively deteriorated 1.76%
A damaged or chafed brake hose can burst and cause sudden brake loss, so it must be replaced promptly.
Tyre tread below 1.6mm 1.62%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Engine oil leak, not excessive (20.06%) · Brake pipes corroded and greasy (14.79%) · Tyre worn close to legal limit (14.46%) · Suspension arm pin/bush showing wear (4.9%) · Brake disc pitted or scored (4.83%) · Brake pads wearing thin (4.79%)
