Tips to help your Asx pass
Based on where Asxes most often fail. For a full list, use our pre-MOT checklist.
Brakes · 7.8% of Asx tests
Don't ignore brake warning signs
Grinding, squealing, a soft pedal or the car pulling to one side under braking are all worth investigating before the MOT. Check whether the last test noted worn pads or discs; if so, they may now be below the limit.
Lights and electrics · 4.8% of Asx tests
Walk round every light
With a helper, check headlights on dipped and main beam, sidelights, brake lights, indicators, the rear fog light and the number plate lamp. Replace blown bulbs in pairs and make sure no lenses are cracked.
