Before your test

Three checks worth doing on a 2018 Astra

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 brakes 1.9% of tests

    “brake pads less than 1.5 mm thick”

    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.

  2. Check the windscreen 1.2% 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.

  3. Check the tyre tread 1.0% 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.

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

What it costs to get a 2018 Astra through its MOT
