BMW 530i misfire despite parts replacement
(Translated from German)
Summary of the thread
A BMW 530i from 2012 is experiencing engine misfires and rough idling, specifically on cylinder 1, despite replacing the injector, ignition coil, and spark plug. A suggested solution is to inspect for vacuum leaks around the intake manifold or hoses, as these could be contributing to the issue.

Check for any vacuum leaks around the intake manifold or hoses, as these can cause rough idling and misfires. Let me know if you find any issues or if the problem persists.
I have already checked the vacuum system, there seems to be no leaks. I was also at BMW and they only say to replace all injectors and coils, they don't say anything more.

Inspect the wiring and connectors for cylinder 1, as a faulty connection can cause misfires. Ensure all connections are secure and free of corrosion. Let me know if this resolves the issue or if you need further assistance.
