does it happen when you start the engine?

A failing belt tensioner damper should show it leaking & produce a random grinding rattle upon start up on some. If that's good, Stock Engine might be right on some pulley.

Some short squeaks yes but cannot be audible if your in an area that isn't as quiet as is in our village... The loud, long squeaks though are as what you heard on the video when in motion. I may have to submit this video evidence so they'll have to look/investigate more.

Can't hear any sir..

A faulty bearing on a pulley or a faulty pulley should produce some grinding even when stationary right? Can't hear any though..

Yes, doc, but let em check the belt...though I doubt it's that. More like pulley/bearing/tensioner.

Would it still be road worthy? My worry is my schedule doesn't permit me to immediately bring it to the dealership and my other car is on the fritz as well so am stuck using my M3. No error codes BTW.. Can I officially declare my car a lemon? Suspension issues, Faulty side mirror retractors, probable tensioner/pulley issues..

Too early for crank pulley. That will cause you codes. Belts can prematurely go if there is some misalignment or resistance. Other pulleys can randomly fail. Check the tensioner for oil leak. It's that lil shock looking thing on the passenger side of the engine. Visible once you pop the bonnet.

Will do sir. But for the time being would a week of use still be ok?

Check your belt condition 1st. If it shows premature wear, some pulley is the culprit. The worst thing that could happen is losing the belt. You'll have to pullover as you won't get the alternator to work. If it's some random bearing sound or a leaky tensioner, you'll be fine. Try not turning the AC on & listen. If it gives you silence, then there's your suspect.
