Top failures
Position lamp not working 2.31%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Airbag warning lamp shows fault 2.01%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Wiper blade not clearing windscreen 1.88%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Dipped beam headlamp not working 1.83%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Direction indicator not working 1.75%
A failed indicator hides your turns from other road users, which is dangerous and must be repaired before driving.
Headlamp aim set too high 1.7%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (11.83%) · Brake disc pitted or scored (8.91%) · Engine oil leak, not excessive (8.03%) · Flexible brake hose slightly deteriorated (4.28%) · Exhaust has minor gas leak (3.89%) · Tyre slightly damaged or cracking (3.89%)
