Before rushing to a repair shop, you can often diagnose and even fix some of these issues yourself. Here’s a step-by-step guide for troubleshooting your 2007 BMW 335i sedan’s sound system:

- Test the speakers: If you have a multimeter, you can test the speakers to ensure they’re functioning correctly.
