  • Timing chain wear

    2.0 petrol and diesel

    The four-cylinder petrol and diesel engines can suffer timing chain wear, especially with late oil changes. A failed chain is an engine-out repair.

  • Blocked EGR valve or particulate filter (diesel)

    Diesel

    Diesels used mostly for short trips can block the EGR valve or clog the particulate filter, causing poor running.

    At the viewing: Ask what journeys it’s done and watch for warning lights or a lack of power.

    If it needs doing: DPF clean or regeneration, about £160–£500. ClickMechanic

  • Noisy differential

    A whine from the rear as the car passes you can mean the differential has been neglected.

    At the viewing: Ask someone to drive it past you slowly and listen for a whine from the back.
