Just under 65k on it. It was never done per the records so I figured it was due for change. The belt wasn't too bad. I would say 10-20k more miles on it would be good before the outer part would start getting work out to the point of being able to be torn. The tensioner I did notice too a little bit less effort to turn compared to the new one. There was a tiny bit of bearing noise/resistant when spun by hand so I'd give it 5-10k more miles. For only costing $42 tensioner/$13 belt it's cheap insurance.

Just be sure to take a peep with a flashlight to see how the belt looks (shiny outside, any cracks on the ribs and any cracks/tears overall)

I've heard that early 2013 production 328i's may have belt/ belt tensioner/ tensioner pulley problems but was fixed for the late 2013 models.
Does anyone know what production month in 2013 they changed/fixed this issue?
