Top failures
Airbag warning lamp shows fault 4.89%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Suspension ball joint excessively worn 2.92%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Tyre tread below 1.6mm 2.6%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Position lamp not working 2.36%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Parking brake efficiency below minimum 2.21%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Suspension arm pin/bush excessively worn 2.13%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Common advisories
Engine oil leak, not excessive (18.05%) · Tyre worn close to legal limit (16.31%) · Brake pipes corroded and greasy (11.43%) · Suspension arm pin/bush showing wear (11.11%) · Suspension ball joint slight play (6.38%) · Tyre slightly damaged or cracking (5.28%)
