Before your test

Three checks worth doing on a 2021 Cayenne

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the windscreen 1.8% of tests

    “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.

  2. Check the tyre tread 0.8% of tests

    “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.

  3. Check the number plates 0.3% of tests

    “registration plates does not conform to the specified requirements”

    Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
