Top failures
Coil spring fractured or broken 5.02%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Position lamp not working 2.96%
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 2.03%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Diesel engine warning light faulty 2%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 1.63%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.48%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Tyre worn close to legal limit (13.89%) · Engine oil leak, not excessive (8.14%) · Brake pipes corroded and greasy (6.93%) · Brake pads wearing thin (3.84%) · Brake disc pitted or scored (3.33%) · Shock absorber light oil misting (2.15%)
