Before your test

Three checks worth doing on a 2018 DS7 C-Back Ultraprstg

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 4.0% 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 brakes 1.8% 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.

  3. Check the lights 1.8% of tests

    “headlamp aim too low”

    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.

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