- Possible Causes:
- Blown fuse: A common culprit, especially after power surges or electrical work on the vehicle.
- Faulty amplifier: The amplifier might have internal issues, causing weak or distorted output.
- Speaker problems: A blown speaker or damaged wiring can lead to sound cutting out or distortion from specific locations.

Identifying and Diagnosing the Problem
- Check the Basics: Start by checking the fuse box for any blown fuses related to the audio system. Inspect visible wiring for damage or loose connections.

- Use Diagnostic Tools: For a more in-depth analysis, professional-grade OBD-II scanners can read error codes from your BMW’s computer system, often pinpointing the problematic area. Some scanners even offer live data streams to monitor audio system performance in real time.
