Top failures
Stop lamp not working 6.63%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Position lamp not working 6.38%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Headlamp beam pattern obviously incorrect 6.3%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Wiper blade not clearing windscreen 4.62%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Registration plate lamp not working 4.44%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Anti-roll bar linkage pin/bush excessively worn 3.94%
Worn linkage pins or bushes cause knocking and poor handling, and can get worse, so they need replacing.
Common advisories
Anti-roll bar linkage pin/bush worn (16.02%) · Tyre worn close to legal limit (13.04%) · Coil spring showing some corrosion (11.56%) · Tyre slightly damaged or cracking (11.39%) · Brake pipes corroded and greasy (9.6%) · Number plate lettering deteriorating (7.95%)
