Average for cars of the same age and mileage
Top failures
Parking brake efficiency below minimum 2.12%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Engine warning light inoperative or lit 2.04%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Lambda reading outside specified limits 1.81%
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
Parking brake inoperative on one side 1.34%
The parking brake does not work on one side, so the car may not hold on a slope and needs repair.
Side repeater not working 1.26%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Parking brake efficiency under half required 1.02%
The parking brake is well below required strength and is unlikely to hold the car on a slope.
Common advisories
Suspension ball joint slight play (5.66%) · Tyre slightly damaged or cracking (4.95%) · Suspension arm pin/bush showing wear (3.85%) · Tyre worn close to legal limit (3.85%) · Brake pads wearing thin (3.14%) · Brake disc pitted or scored (2.91%)
