Tips to help your i800 pass
Based on where i800s most often fail. For a full list, use our pre-MOT checklist.
Lights and electrics · 22.6% of i800 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.
Brakes · 12.2% of i800 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.
Visibility · 6.3% of i800 tests
Clear the view
Replace wiper blades that smear, fill the washer bottle and get chips in the windscreen repaired early, especially in the area directly in front of the driver.
