Skoda Karoq cold start issue

I'm facing a perplexing issue with my 2020 Skoda Karoq, equipped with a gasoline engine. The problem is poor engine running during cold starts, resulting in difficult vehicle starts. I suspect a faulty cold start injector. Has anyone encountered a similar situation, and could offer insights or recommendations regarding potential diagnostic procedures or repair strategies? I'm thinking it's related to the fuel system. Any thoughts on injector cleaning?

Summary of the thread

Rough idle on a cold start with your Skoda Karoq? Sounds like a fuel delivery issue, and you're right, the injector is prime suspect. Before condemning it outright, have you tried any injector cleaning additives in your fuel system? Also, can you hear any unusual ticking or clicking noises from the injectors themselves? A long screwdriver used as a stethoscope can help isolate a noisy injector. Have you checked the fuel pressure regulator? A faulty regulator can cause lean running conditions, exacerbating cold start issues. Could you provide more details about the engine? Is it direct injection (TSI)?

Thanks for the detailed response. I haven't tried any fuel additives yet. I was a bit hesitant. As for the ticking, I haven't specifically listened for it. And yes, it's a TSI engine. About the fuel pressure regulator, where is it located, and how can I check it?

Okay, with a TSI engine, the fuel pressure regulator is usually integrated into the high-pressure fuel pump, which is driven by the camshaft. Checking it properly requires specialized tools to measure the fuel pressure. Given the symptoms and the TSI engine, a faulty injector is the most probable cause. A proper diagnosis needs specific tools, and working on the high-pressure fuel system can be dangerous. My recommendation would be to take it to a workshop to confirm the diagnosis and get it repaired professionally.

Took the Karoq to a workshop. They confirmed it was the cold start injector. Replacement cost 515€. Engine runs smoothly now, even on cold starts. Thanks for the advice.
