I replaced the belt on my 2011 X5 with the N55. While watching it run, the belt tensioner seemed to bounce around/move a lot! I have a video link below, but the tensioner was moving so fast, the frame rate didn't capture all of the movement. I replaced the belt tensioner a couple of years ago with an OEM supplier INA one. I can't recall watching it at that time (I should have so I had a baseline). Is this normal? I've never seen this much movement in a belt tensioner. What does your belt tensioner look like while running? Thanks.
