Top failures
Parking brake efficiency below minimum 2.45%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Side repeater not working 2.37%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Tyre tread below 1.6mm 2.17%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.89%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Position lamp not working 1.77%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Tyre cut reaching ply or cords 1.57%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre worn close to legal limit (16.25%) · Brake disc pitted or scored (6.76%) · Suspension arm pin/bush showing wear (4.38%) · Brake pads wearing thin (3.94%) · Exhaust mounting defective (3.94%) · Engine oil leak, not excessive (3.5%)
