Hi Land Rover experts!

My 2018 Discovery 5 has started making this noise ( video also attached to this post ).

At idle it makes this chirping sound, but randomly while driving it becomes more of a squeal. I haven't found a pattern to the squeal while driving yet, it does feel completely random, but at times can be quite loud.

I'm thinking fan belt ( serpentine belt ), but wanted to get some other opinions before I go further down that road. I'm realtively handy with car DIY and would love additional advice on level of difficulty / cost of this fix.

Thanks in advance!

 

Sounds like a supercharger coupler. Do a search and you’ll find more info. Common issue as the miles get up there
