The m104 in my car is making a weird noise. I havent had the time to sit there and play with the belt and tensioner to make sure its working properly.

The noise sounds like if you took a latex balloon and rubbed your hand just in a rotational manner... example "squer squer squer" thats what I hear. It doesn't increase as much with the revs which probably means its something pulley related and its coming from the front. Can't point to exactly where.
