Citroen C3 engine running unevenly

My 2017 Citroen C3 gasoline, with 231222 km, has an uneven engine. The check engine light is on, there's an error stored, and it jerks when accelerating. Could this be the fuel pump or oxygen sensor?

Rough idle and jerking... sounds familiar. I had similar issues with my old Opel Astra. Check engine light was on too. Does it happen more when the engine is cold?

Thanks! Yes, the rough idle and jerking are definitely more noticeable when the engine is cold. What was the problem with your Astra? Could it be the same with my C3?

Turned out to be a leak in the exhaust system. Symptoms were very similar: engine misfire, error codes... might be worth getting it checked by a workshop. Difficult to diagnose these things remotely. I paid 265€ for the repair.

Thank you very much! Based on your experience, I will take it to a workshop and have the exhaust system checked for leaks. I really appreciate your help!
