Average for cars of the same age and mileage
Top failures
Headlamp beam pattern obviously incorrect 4.13%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Position lamp not working 3.8%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Tyre ply or cords exposed 2.75%
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 2.65%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
CV joint boot split or insecure 2.38%
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 2.25%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Common advisories
Tyre worn close to legal limit (18.93%) · Suspension arm pin/bush showing wear (14.94%) · Engine oil leak, not excessive (10.89%) · Brake disc pitted or scored (10.46%) · Shock absorber light oil misting (7.99%) · Brake pads wearing thin (7.69%)
