Peugeot 206 diesel engine running lean

I encountered a similar issue with my 206. Symptoms included reduced power and rough running. I suspect a defective injector could be the culprit. Have you checked the air-fuel ratio or considered a potential issue with the catalytic converter?

Thanks for the quick reply! I haven't checked the air-fuel ratio myself, and I haven't considered the catalytic converter. How did you resolve your issue? Was it definitely the fuel injectors?

In my case, the issue was traced back to faulty fuel injectors. Given your symptoms, specifically the jerking, a defective injector seems probable. While it could also be related to the throttle body, the check engine light points toward a more specific issue. I would recommend a visit to a workshop to confirm the diagnosis.

Okay, thanks a lot for the advice! I'll take it to a workshop and mention the fuel injectors. It was a defective injector! The total repair cost was 515€. Thanks again for your help!
