Pre-MOT Inspection Checklist for Kia Stonic GT-Line Isg Owners

These checks follow this Kia Stonic GT-Line Isg's own most-recorded failure strings, starting with what a tester is most likely to flag on a Kia Stonic GT-Line Isg.

• the wipers and washers — “wipers does not clear the windscreen effectively”

  Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.

• the lights — “headlamp aim too low”

  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.
