Top failures
Stop lamp not working 1.06%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Lambda reading outside specified limits 0.99%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Coil spring fractured or broken 0.8%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Wiper blade not clearing windscreen 0.8%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp aim set too high 0.78%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Rigid brake pipe excessively corroded 0.73%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Common advisories
Brake disc pitted or scored (8.99%) · Brake pipes corroded and greasy (6.88%) · Tyre worn close to legal limit (6.74%) · Tyre slightly damaged or cracking (6.69%) · Slight play in steering rack joints (4.38%) · Engine oil leak, not excessive (2.44%)
