Insignia rough cold start

My 2021 Vauxhall Insignia petrol with 130k km is starting rough when cold. The engine runs poorly until it warms up, and it often takes a couple of tries to get it going. Could this be a fueling issue? Perhaps an injector fault?

Sounds familiar. I had something similar with my Insignia. Have you checked the fuel rail pressure? Also, have you considered getting the injectors tested?

Thanks for the quick response! I haven't checked the fuel rail pressure yet. How would I go about testing the injectors? Is that a DIY job or best left to a professional?

For injector testing, I'd recommend a workshop. Could be cold start injector playing up. If it's like mine was, faulty injector is odds-on your problem.

Took it to a garage, and you were spot on. Turns out the cold start injector was defective. New injector fitted and all good now. Cost me 515€.
