Why is my BMW 1 Series making a loud squeaking noise while driving?

I recently purchased a BMW 1 Series and I have noticed a loud squeaking noise while driving. I'm not sure what could be causing it, any ideas?

It could be due to your brake pads wearing out. It's important to get them checked and replaced if necessary to avoid further damage. I would recommend taking it to a certified mechanic for a thorough inspection.

Another possible cause could be a worn out serpentine belt. It's responsible for powering various components in your engine and if it's worn out, it could be causing the noise. I would suggest taking it to a trusted mechanic for a proper diagnosis and replacement if needed.

I had a similar issue with my BMW 1 Series and it turned out to be a loose exhaust pipe. It was an easy fix but I would still recommend getting it checked by a professional to ensure there are no underlying issues.
