It just happened to me today, was just driving down the street for about 30minutes in, was hot outside and all of sudden my engine didnt sound right, and noticed some turbo spooling noises that was much louder than usually after 2k rpm. pulled over to the side of the road turned off the car and restarted it.... and revved it the sound was gone after that???? Im not sure what happened so ill be taking it to the dealer this saturday to have them have a look...only 3.3k miles on it

and already having this weird noise is something im not looking forward to
