Loud Whirring from Rear Passenger Side - 20 Q5 P+
 

Hi all,

2020 Q5 Premium Plus.

I've been hearing a bit of a whirring sound after turning off the car, coming from the rear right passenger side around where the fuel filler is. Never heard it before until the past two - three months. Dealer couldn't find anything wrong.

Now today, the noise (if it's even the same one) is much louder, and a loud pop and the noise stopped after the engine cooling fans turned off. Attached a video, might need headphones to hear the engine fan spin down.

Appreciate any input anyone has on this!

Your fault codes?

Pretty sure my 2020 makes similar sounds. Understand it to be the Evap emissions system self testing itself for leaks. If you open your gas cap while that is going on you will get a code.
All normal. Works differently from 2021 onward I am told.
