Pre-MOT Inspection Checklist for Audi A8 L Owners

These checks follow this Audi A8 L's own most-recorded failure strings, starting with what a tester is most likely to flag on a Audi A8 L.

  • 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 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 high”

    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.

Derived from the DVSA failure strings testers recorded for the Audi A8 L. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
