Mine makes that sound too. I've brought it in to Tesla and they tell me it's "normal," but everytime I'm at a SuC the car sounds like it's ready to take off and people stare at it concerned that's it's gonna kersplode. I'm convinced a bearing surface is worn out which is causing the whine vs an expected fan whirring.
That sound is definately not normal. I have had 3 fans replaced in 4 years (2015 MS P90D) 3 under warranty 1 under extended warranty. - I feel that qualifies my as an expert.
That sound is the inner bearing and it will gradually get worse and worse. There is a new versions of the fan which came out about 12 months ago that has an updated centre bearing to overcome this repetative problem. Don't let them tell you it's normal. It is not and the fans do not sound like that when new. I've attached my last invoice fan change and 12 volt battery replacement (August 2019) the invoice stats 'customer pays' however that is simply because it was done under EXTENDED warranty the preiouse ones listed as warranty/goodwill. My fans were making the exact sound as per your clip.
It's not normal, mobile service replaced my drivers side condenser fan because of the squeak and now my passenger side is doing it. I let them know and they ordered the part to replace that one as well.
Mine does the same. The high pitching noise is even so loud, that you can hear it during slow drive in the cabin. Prague Service Center Lite was UNABLE to find the source of the noise despite keeping the car for TWO days. Thats not a service center, thats a bad joke.
