Pre-MOT Inspection Checklist for Toyota Prius T3 Vvt-I Owners

These checks follow this Toyota Prius T3 Vvt-I's own most-recorded failure strings, starting with what a tester is most likely to flag on a Toyota Prius T3 Vvt-I.

• 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 tyre tread — “tread depth below requirements of 1.6mm”

  Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

• the lights — “headlamp aim too low and too far to the left.”

  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.
