Known faults on the 2015 Citroen C1

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.

• Steering column recall (very early cars)

  Built Sept to Oct 2014

  A small batch of cars built in September and October 2014 was recalled because the steering column could collapse.

  At the viewing: If the car was built in late 2014, ask a dealer to check the VIN for the recall.

• Clunky 2-Tronic automatic

  2-Tronic / x-shift automatic

  The optional 2-Tronic is an automated manual, not a true automatic. It can feel jerky and owners rate it poorly.

  At the viewing: Drive it in traffic and pull away several times. Make sure you can live with how it changes gear.

• Engine turns over but won't start

  All engines

  Some owners report the engine cranking without firing. A tired battery is the usual cause.

  At the viewing: Start the car from cold yourself and watch for slow cranking.

Questions to ask the seller before buying a 2015 Citroen C1

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. Has all the recall work been done?
3. Has the gearbox or clutch had any work?
4. How old is the battery?
5. Any recent work on the anti-roll bar link bushes? (Flagged at MOT 27.5× as often on the 2015 Citroen C1 as on other cars the same age.)
6. Any recent work on the rigid brake pipes? (Flagged at MOT 3.3× as often on the 2015 Citroen C1 as on other cars the same age.)
