If the check engine light is on in your 2004 BMW 325i, it indicates that the vehicle's onboard diagnostics system has detected an issue. Common causes can include problems with the oxygen sensor, mass airflow sensor, or issues related to the ignition system. It's best to use an OBD-II scanner to retrieve the specific trouble codes and diagnose the issue accurately. If you're unsure, consider visiting a professional mechanic for a comprehensive inspection.
