Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 5.32%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
CV joint boot split or insecure 4.7%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Tyre tread below 1.6mm 3.21%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Diesel engine warning light faulty 2.19%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Headlamp aim set too low 1.78%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Headlamp beam pattern obviously incorrect 1.77%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Common advisories
Tyre worn close to legal limit (17.87%) · Suspension arm pin/bush showing wear (13.74%) · Brake disc pitted or scored (7.96%) · Brake pads wearing thin (7.55%) · Tyre slightly damaged or cracking (4.5%) · Shock absorber light oil misting (4.12%)
