Megane cold start issue

I own a 2012 Renault Megane with a gasoline engine and 227717 km. The engine runs poorly during cold starts. It starts roughly. Could it be a faulty cold start injector?

Hey, I had similar issues on my Megane. Rough idle and engine misfires when cold. Does it improve after a few minutes?

Indeed, it does improve after a few minutes. Could you please provide more details about your experience with this issue?

Well, it turned out to be a defective injector. I tried injector cleaning, but it didn't solve the problem. Eventually, I took it to a workshop. They diagnosed a faulty injection valve, replaced the injector, and checked the fuel rail.

Thank you for the information. I visited my local mechanic. They identified the same issue. The repair cost 515€. I appreciate your help.
