Top failures
Tyre cut reaching ply or cords 1.11%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre bulge from structural failure 0.56%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Diesel engine warning light faulty 0.56%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 0.46%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Side repeater not working 0.37%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Number plate does not meet standards 0.37%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Common advisories
Tyre worn close to legal limit (3.25%) · Nail in tyre, monitor (1.48%) · Tyre has a shallow cut (1.3%) · Brake pads wearing thin (0.74%) · Child seat limits belt inspection (0.56%) · Tyre slightly damaged or cracking (0.56%)
