Known faults on the 2017 DS 4

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

• Timing belt that runs in oil (PureTech petrol)

  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.

Questions to ask the seller before buying a 2017 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 7.1× as often on the 2017 DS 4 as on other cars the same age.)
3. Any recent work on the number plate lights? (Flagged at MOT 4.8× as often on the 2017 DS 4 as on other cars the same age.)
4. Any recent work on the coil springs? (Flagged at MOT 2.8× as often on the 2017 DS 4 as on other cars the same age.)
5. Can I see the service history and receipts for any big jobs?
