Weird high squealing sound from engine bay.

Hey guys,

Proud owner of my C43 for about 1 week now. I'm not sure why but every time I park my car and turn off the engine there's a high squealing noise coming out of the engine bay. I can't pin point exactly where it is and it doesn't sound like anything is moving either. This happens about 15-20mins after I've parked.

Please see the videos in the attched link to know to know exactly what I mean. It will last for an unknown period of time but I've been listening to it for over 15mins already.

I've called my dealership and they said it's normal. I don't want to waste time bringing it in if it really is nothing but have you guys had the same experience? Do your w205 C43 make that weird noise while parked with the engine off too?
