Pre-MOT Inspection Checklist for Fiat 500 Star Twinair Owners

These checks follow this Fiat 500 Star Twinair's own most-recorded failure strings, starting with what a tester is most likely to flag on a Fiat 500 Star Twinair.

• the wipers and washers — “washers provides insufficient washer liquid”

  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 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 significantly and obviously worn”

  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.
