Pre-MOT Inspection Checklist for Piaggio Porter Owners

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

• the lights — “headlamp reflector 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 exhaust and emissions — “exhaust system has a major leak of exhaust gases”

  Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

• 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.
