Top failures
Brake pads worn below 1.5mm 2.8%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 1.45%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre tread below 1.6mm 1.36%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Windscreen washer fluid insufficient 1.09%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Stop lamp not working 1.08%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Dipped beam headlamp not working 1.06%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Common advisories
Brake pads wearing thin (11.28%) · Tyre worn close to legal limit (10.08%) · Tyre slightly damaged or cracking (9.2%) · Brake disc pitted or scored (5.54%) · Brake discs showing some wear (3.03%) · Child seat limits belt inspection (2.33%)
