Thanks for the reply. Can you provide more details on which onboard diagnostics you are referring to? Is there a specific reset procedure?

Yes, the error does indeed sound like a faulty injector. In my case, I tried several resets, but it didn't help. I recommend you to visit a workshop with diagnostic equipment. They can check the sensors and control the injection quantity. I ended up having to replace the injectors. Good luck!

Thanks for the info! Took it to the workshop, and you were right. Defective injector. Repair cost was 515€. Runs smoothly again.

Hello! I experienced a similar problem with my older Opel Astra. The error message was different, but it also pointed to fuel injection issues. It might be necessary to perform a system reset. Did you already check the onboard diagnostics?
