Troubleshooting Tips:
* Listen carefully: Try to pinpoint the exact location of the noise. Does it change with engine RPM?
* Visual inspection: Check for obvious signs of wear or damage to the supercharger belt, tensioner, and surrounding components.
* Professional inspection: If you're not comfortable diagnosing the problem yourself, take your car to a qualified mechanic who specializes in supercharged vehicles.
Important Note: It's crucial to address any unusual noises promptly to avoid further damage and potential safety hazards.
