Top failures
CV joint boot split or insecure 6.86%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Position lamp not working 4.86%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Exhaust has major gas leak 4.29%
A major exhaust leak can let poisonous gas into the car and is illegal, so it must be repaired before driving.
Rigid brake pipe excessively corroded 2.95%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Stop lamp not working 2.67%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Anti-roll bar linkage ball joint worn 2.67%
A worn linkage ball joint can rattle, affect handling and eventually fail, so it should be replaced.
Common advisories
Engine oil leak, not excessive (22.38%) · Brake pipes corroded and greasy (20.57%) · Wheel bearing slight play (10.95%) · Chassis corroded but still rigid (7.43%) · Tyre worn close to legal limit (7.24%) · Brake disc pitted or scored (6.86%)
