Captur Hybrid Engine Problems

I'm having trouble with my 2021 Renault Captur Hybrid. It's done 203217 km. The check engine light came on, engine power is reduced, and it's running rough. It jerks when accelerating and sometimes stalls. I suspect a mixture preparation error; could it be a defective injector? I've checked for intake manifold leaks, and the mass airflow sensor seems fine. I'm worried it might be the catalytic converter. Any thoughts?

Whoa, that sounds familiar! I had almost the exact same symptoms with my Captur! Check engine light and all. Though, I don't know what any of those fancy terms you used actually mean. What kind of mileage are you getting?

Thanks! I'm averaging around 5.2 L/100km. Did you also experience jerking when accelerating and stalling at idle, as well as the check engine light? Was it indeed a mixture preparation error as well? What was the final diagnosis in your case?

Yep, jerking and stalling exactly like you described! Honestly, I got freaked out and took it straight to a workshop. They sorted it out, but I don't remember exactly what they did. Best to get it checked!

Thank you for confirming my suspicions and sharing your experience! It seems prudent to have it professionally diagnosed. I've taken it to my local mechanic, and it was indeed a defective injector. The repair cost me 515€. Hopefully, this resolves the issue permanently.
