BMW 535i 2008 serpentine belt

after 74,000 miles, my bmw serpentine belt broke and I think because there was an oil leak. I changed a new serpentine belt, and 2 months later I fixed the leak, and now the new serpentine belt is broke again at 80,000 miles . I just want to know what caused the problem again. is it the oil leak or maybe the tensioner has to be replaced?
(pulley bearings and tensioner dont shake and dont make any noise )
I attached an image showing the serpentine belt:
