Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.88%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.4%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 1.4%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Stop lamp not working 1.3%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Diesel engine warning light faulty 1.3%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Engine warning light inoperative or lit 1.11%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
