Top failures
Side repeater not working 4.07%
A failed side repeater means other road users cannot see your intended direction change, which is dangerous and must be fixed.
Coil spring fractured or broken 2.72%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Windscreen washer fluid insufficient 2.39%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Rigid brake pipe excessively corroded 2.37%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Headlamp beam pattern obviously incorrect 2.26%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Suspension ball joint excessively worn 1.99%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Common advisories
Brake pipes corroded and greasy (15.02%) · Tyre worn close to legal limit (12.2%) · Tyre slightly damaged or cracking (10.33%) · Brake disc pitted or scored (8.48%) · Brake pads wearing thin (5.51%) · Shock absorber light oil misting (2.57%)
