Average for cars of the same age and mileage
Top failures
Position lamp not working 3.29%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Airbag warning lamp shows fault 2.99%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Parking brake efficiency below minimum 2.56%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Dipped beam headlamp not working 2.38%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Stop lamp not working 2.38%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Tyre tread below 1.6mm 2.2%
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 (16.47%) · Engine oil leak, not excessive (9.09%) · Brake disc pitted or scored (8.3%) · Brake pipes corroded and greasy (6.65%) · Anti-roll bar linkage pin/bush worn (4.39%) · Slight play in steering rack joints (4.09%)
