Pre-MOT Inspection Checklist for Lexus LS430 Owners

These checks follow this Lexus LS430's own most-recorded failure strings, starting with what a tester is most likely to flag on a Lexus LS430.

• the lights — “headlamp lens 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 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 battery — “battery(ies) insecure”

  Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.

Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
