On the 2014-2026 Citroen C3 1.2L PureTech, pSA/Stellantis PureTech 1.2 (EB2) engines run an oil-immersed ("wet") timing belt instead of a chain. The belt's outer rubber layer can delaminate and shed particles into the oil pickup, clogging the strainer and starving the engine of oil. Stellantis revised the belt material and shortened the service interval (now 60,000 mi or 6 years, whichever first) but earlier-spec belts still in service are at risk.

This issue also affects: Citroen C4, Citroen DS3, Peugeot 2008

Common Symptoms

  • Rattling on cold start
  • Engine warning light
  • Misfires
  • Power loss

How to Fix

Replace the timing chain, tensioner, and sprockets with revised parts. Check eligibility for PSA extended warranty (10 years/200,000km). Use only manufacturer-specified oil.
