Belt Cracked

[HotRodM4]

63k miles on my 2018 M4. I notice this belt cracking. See pics.

What part number do I need to replace this? Or any recommendations? Car is out of warranty.

Appreciate the quick response. Any other belts or anything else to replace while I’m there? Or it’s just the serpentine belt by itself?

DIY here:

Since you also have to take off the water pump belt in order to change the serpentine belt, should renew that one while you're at it

As someone else mentioned, you might as well replace the accessory belt.

The water pump is driven with a different belt.

I replaced my belts not long time ago, I also replaced the pulleys and tensor

I think I saw your picture on fb group, I'm at 63k so I'm wondering if I should do this as a preventative (belts + tensioner + pully)

Would you be able to share the total cost?

I had a mild belt chirp only when cold for around 4K miles but it’s died down now

BMW
Wanted €3500 to change belts!

I’d still
Like to get it done as my F82 is getting better with each drive.

Ideally I’d like to keep it forever
