Pre-MOT Inspection Checklist for MG 3 Form Owners

These checks follow this MG 3 Form's own most-recorded failure strings, starting with what a tester is most likely to flag on a MG 3 Form.

• the lights — “headlamp lens slightly defective”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the brakes — “brake discs in such a condition that it is seriously weakened”

  Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
