Serpentine belt

favenebula · 04-30-2024, 08:52 AM

Hi guys I’m new to bmw and still new to doing stuff myself, I’ve ordered a new belt as I’m getting noises but the old belt looks strange and I can’t find any pictures that look like it. Have attached old and new pictures
Thank you in advance

The old picture doesn't appear to be an OEM belt.

not sure what that old belt is but nothing screams problems with it based on that one photo. What kinda noises are you dealing with?

Hi thanks for replying, it’s a whistle a chirp and a grinding? Like a skateboard wheel

Sounds like the bearing on a pulley/tensioner. Changing the belt likely won't solve that issue.

My belt would sometime chirp on launch skipping a little because of torque off the line. Doesn’t seem to do it anymore since I got mppsk, got a new one put in due to mileage.
