Top failures
Tyre tread below 1.6mm 1.8%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Anti-roll bar linkage ball joint worn 1.04%
A worn linkage ball joint can rattle, affect handling and eventually fail, so it should be replaced.
Tyre cut reaching ply or cords 0.96%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Windscreen washer fluid insufficient 0.85%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Lambda reading outside specified limits 0.74%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Tyre ply or cords exposed 0.66%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (13.36%) · Tyre slightly damaged or cracking (9.79%) · Brake disc pitted or scored (5.99%) · Child seat limits belt inspection (4.05%) · Brake pads wearing thin (2.41%) · Nail in tyre, monitor (2.35%)
