Top failures
Wiper blade not clearing windscreen 1.94%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Service brake excessively binding 1.7%
A brake that drags when released can overheat, wear quickly and waste fuel, so it needs prompt inspection.
Tyre tread below 1.6mm 1.69%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Registration plate lamp not working 1.35%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Fuel filler cap ineffective 1.34%
A faulty fuel cap can let fuel vapour escape and may trigger warning lights, so a replacement is usually simple.
Headlamp aim set too low 1.28%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Common advisories
Tyre worn close to legal limit (11.74%) · Tyre slightly damaged or cracking (10.5%) · Brake disc pitted or scored (6.47%) · Brake pads wearing thin (4.73%) · Suspension arm pin/bush showing wear (3.95%) · Service brake slightly binding (3.19%)
