Here is the problem and I checked with a very experience SA at TC (who became a fren of sorts)
The tension in the belt is causing the sound....
It is the RIGHT tension... not just make it tighter...
I had this problem when I changed it at my wshop, then can;t fix, when to TC ask my SA, he says tension.
But, tension is a trial and error thing for the mechanic... no measurement... so even at TC may also be like that...
Just go back to ur whsop and ask them to adjust (not tighten only may loosen) the tension.
Too tight, got sound.....
