Top failures
Engine warning light inoperative or lit 2.7%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
ABS warning lamp shows a fault 2.38%
A lit ABS warning means the anti-lock system may not work, so wheels could lock during emergency braking.
Suspension arm pin/bush excessively worn 2.11%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Suspension mounting area seriously corroded 1.94%
Corrosion near suspension mountings can seriously weaken the body structure, so an expert inspection is needed.
Wiper blade not clearing windscreen 1.57%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Parking brake efficiency below minimum 1.35%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Common advisories
Tyre worn close to legal limit (9.56%) · Tyre slightly damaged or cracking (5.13%) · Suspension mounting area showing corrosion (5.02%) · Wheel bearing slight play (4.7%) · Brake disc pitted or scored (4.43%) · Brake pipes corroded and greasy (4.27%)
