Peugeot 508 Cold Start Issue

I had a similar issue with my 2016 Opel Astra, although the engine type was different. It also struggled to start when cold and ran rough for the first few minutes. Turned out to be a faulty injector. Have you checked for any error codes? That might help narrow it down.

Thanks! I did an initial scan, but no relevant codes came up that directly pointed to the injectors. Do you remember the specific error codes your Astra showed? That might help me.

Unfortunately, I don't recall the exact error code. It was a while ago. But if you're not getting any codes and the symptoms are similar, it might be worth having a workshop take a closer look at the injectors. They have specialized equipment to test them properly. Saved me a lot of headaches in the long run.

I took it to a workshop specializing in fuel injection systems. They agreed it was likely a defective injector and needed replacement. Total cost was 515€. The car is running as expected now. Thanks again!
