Top failures
Wiper blade not clearing windscreen 1.1%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp aim set too low 0.59%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre cut reaching ply or cords 0.51%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake pads worn below 1.5mm 0.42%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre pressure monitoring system faulty 0.34%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Lambda reading outside specified limits 0.34%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Common advisories
Tyre worn close to legal limit (6.44%) · Brake pads wearing thin (3.56%) · Brake disc pitted or scored (2.8%) · Tyre slightly damaged or cracking (1.69%) · Tyre worn close to legal limit (1.02%) · Brake discs showing some wear (0.93%)
