Pre-MOT Inspection Checklist for Toyota GR86 D-4S Owners

These checks follow this Toyota GR86 D-4S's own most-recorded failure strings, starting with what a tester is most likely to flag on a Toyota GR86 D-4S.

• the exhaust and emissions — “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

  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 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 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.
