Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.99%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.83%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Suspension arm pin/bush excessively worn 1.37%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Coil spring fractured or broken 1.35%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Registration plate lamp not working 0.94%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
LED or HID headlamp cleaner inoperative 0.77%
Without a working cleaner, dirt can build up on LED or HID lenses and reduce light output, so repair is needed.
Common advisories
Tyre worn close to legal limit (14.11%) · Suspension arm pin/bush showing wear (6.34%) · Brake disc pitted or scored (4.3%) · Brake pads wearing thin (3.97%) · Sub-frame showing corrosion (2.93%) · Tyre slightly damaged or cracking (2.67%)
