Peugeot and Citroen issued a recall in 2021 relating to the wet timing belt degrading and causing restricted oil flow within the engine, which could cause significant damage. Although we would expect any car affected to have had rectification work carried out, it is possible that there are cars out there that have not been using the correct oil grade. We would expect a replacement timing belt to cost between £400 and £600.
