Average for cars of the same age and mileage
Top failures
CV joint boot split or insecure 6.25%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Suspension arm pin/bush excessively worn 4.71%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Position lamp not working 4.22%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Suspension ball joint excessively worn 3.6%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Headlamp beam pattern obviously incorrect 3.5%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Tyre tread below 1.6mm 2.42%
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 (15.71%) · Suspension arm pin/bush showing wear (15.61%) · Engine oil leak, not excessive (15.16%) · Brake disc pitted or scored (14.6%) · Brake pipes corroded and greasy (11.69%) · Coil spring showing some corrosion (7.17%)
