By the way my belt was changed 35 000km ago for making the same noise. Solve the problem for almost 2 years but it seems quick to get it back.
Thanks.
I have the same problem as of recently...When the car is cold I have what seems to be the belt making a little bit of noise that sounds similar to the rotations of the belt...Cant confirm if it happens when "humid"...
It only started recently for me about the last <1000 miles....one of my buddies with a 335i had the same issue and he sprayed "lubricant" on it and it quiets it down....Obviously not a solution LOL but it works if the noise bugs you....I remember he carried it around in his trunk and would pop his hood before cruises and spray it was pretty funny but now I have the same issue haha...He drove many thousand miles with it just for your information and never got the chance to swap the belt before he sold the car...
