Top failures
CV joint boot split or insecure 2.24%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Rigid brake pipe excessively corroded 1.33%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Position lamp not working 1.28%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Diesel engine warning light faulty 1.28%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Parking brake efficiency below minimum 0.96%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre tread below 1.6mm 0.82%
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 (9.34%) · Engine oil leak, not excessive (7.33%) · Brake pipes corroded and greasy (6.18%) · Brake disc pitted or scored (4.58%) · Brake pads wearing thin (3.43%) · Tyre slightly damaged or cracking (1.69%)
