Top failures
Headlamp beam pattern obviously incorrect 6.41%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Position lamp not working 5.76%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Dipped beam headlamp not working 5.68%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Brake pads worn below 1.5mm 3.14%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Diesel engine warning light faulty 2.84%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Headlamp aim set too high 2.66%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
