Average for cars of the same age and mileage
Top failures
Lambda reading outside specified limits 5.23%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Suspension mounting area seriously corroded 4.91%
Corrosion near suspension mountings can seriously weaken the body structure, so an expert inspection is needed.
Wiper blade not clearing windscreen 2.48%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
ABS warning lamp shows a fault 2.21%
A lit ABS warning means the anti-lock system may not work, so wheels could lock during emergency braking.
Carbon monoxide high after fast idle 1.94%
High carbon monoxide can point to engine or catalytic converter faults, so ask for diagnosis before buying.
Seat belt anchor area weakened 1.94%
Corrosion near a seat belt anchor can weaken the body and make the belt fail, so expert repair is needed.
Common advisories
Brake pipes corroded and greasy (9.82%) · Tyre slightly damaged or cracking (7.87%) · Tyre worn close to legal limit (6.96%) · Suspension mounting area showing corrosion (6.26%) · Coil spring showing some corrosion (6.09%) · Engine oil leak, not excessive (5.39%)
