What usually goes wrong with a DS 4?

Known faults reported by owners, mechanics and UK buying guides, in our own words. Most apply to certain years or engines only, so check which the car has.

  • Timing belt that runs in oil (PureTech petrol)

    Cars registered 2015–2025 · 1.0 and 1.2 PureTech petrol

    The 1.0 and 1.2 PureTech petrol engines use a timing belt that runs in the engine oil (a “wet belt”). It can break down early and shed rubber that blocks the oil supply, which can wreck the engine. Some also burn too much oil. Stellantis now covers earlier engines for belt and oil-burning problems for up to 10 years or 112,000 miles, as long as the car has been serviced on schedule.

    At the viewing: Ask for a full service history showing the right oil, and when the belt was last checked or changed. Check the oil level on the dipstick, and that no oil-pressure or engine warning light stays on.

Common DS 4 MOT failures to check

Parts flagged at MOT well above the usual rate for cars the same age, in more than one year. From the DVSA’s results for every MOT done in Great Britain during 2023–2025.

  • Drive shaft (CV) joints

    up to 8.9× usual

    Stands out on cars registered in 2015, 2016, 2017 and 2018.

    Rough price £60–£350 our estimate

    At the viewing: Drive slowly on full steering lock in both directions and listen for clicking. Look for split rubber boots behind the front wheels.

  • Number plate lights

    up to 8× usual

    Stands out on cars registered in 2015, 2016, 2017 and 2018.

    Rough price £5–£40 our estimate

    At the viewing: Check the number plate lights work and the plates are clean and legal.

  • Coil springs

    up to 7× usual

    Stands out on cars registered in 2015, 2016, 2017 and 2018.

    Rough price £175–£400 (pair, one axle) ClickMechanic

    At the viewing: Look behind each wheel for a snapped spring coil, and listen for a clunk or twang when turning the wheel lock to lock with the car stopped.

  • Brake discs

    up to 2.2× usual

    Stands out on cars registered in 2017, 2018 and 2022.

    Rough price £150–£350 our estimate

    At the viewing: Look through the wheel at the brake disc: a deep lip at the edge or heavy scoring means they're worn. Feel for judder when braking.

Questions to ask the seller before buying a DS 4

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

  1. When was the timing belt last checked or changed, and has it had the right oil at every service? Is the car still within Stellantis’ extended PureTech cover?
  2. Any recent work on the drive shaft (cv) joints? (Flagged at MOT 8.9× as often on the DS 4 as on other cars the same age.)
  3. Any recent work on the number plate lights? (Flagged at MOT 8× as often on the DS 4 as on other cars the same age.)
  4. Any recent work on the coil springs? (Flagged at MOT 7× as often on the DS 4 as on other cars the same age.)
  5. Can I see the service history and receipts for any big jobs?
