Peugeot 5008 cold start injector issue

I had something similar on my 5008. Difficult cold starts and rough running until it warmed up. Have you checked the fuel rail pressure? It might be worth getting an injector test done before replacing anything.

Thank you for your response. Regarding the injector test, what specific parameters should I be looking at to confirm a defective injector? I am considering performing an injector cleaning. Would you advise against this?

In my case, the injector spray pattern was clearly off during the test. Cleaning might help temporarily, but if the injector is truly defective, it will likely return. It's like putting a band-aid on a broken leg. If it persists, I'd recommend visiting the workshop.

Thank you for your insight. The diagnosis confirms a defective injection valve/injector. Repair cost is estimated at 515€. I appreciate your shared experience.
