Grandland X cold start problems

I had similar cold start problems with my old Renault Megane, although it was a diesel. Hard starting and rough running when cold. Have you checked the fuel rail pressure? That was the culprit on mine. What about the injection valves?

Thanks! Fuel rail pressure is something I hadn't considered. How did you diagnose the issue with your Megane, and what was the fix?

I wasn't able to fix this myself. I took it to a workshop. The guys there told me it was a defective injector and replaced it. So I suggest you also check the injection valves.

I appreciate the advice. I took it to the workshop, and it was indeed the fuel injector, as suspected! They replaced the defective injection valve and the total repair cost came to 515€. Thanks again for pointing me in the right direction!
