Citroen DS4 cold start issue

I'm having a rough time with my 2014 Citroen DS4 gasoline. It's got 229047 km on the clock. The engine runs really poorly when it's cold, and it starts terribly. Could it be the cold start injector?

Sounds familiar! I had similar issues with my old Volvo, but it was another injector. Have you checked the fuel rail pressure? Maybe that's the culprit?

Fuel rail pressure, huh? How would I go about checking that? Is it something I can do myself, or am I better off taking it to a professional?

Honestly, with fuel pressure, it's best to leave it to a workshop unless you really know your way around engines. Could be a dodgy injector like you first thought. I went to the workshop with my Volvo in the end.

Thanks for the advice! I took it to the shop and you were right, the cold start injector was defective. Cost me 515€ to replace, but it's running like new again!
