Faint high pitch sound (like a vacuum cleaner or jet engine whine) when accelerating and regen braking (front right)

Hi,

I just noticed a new sound on my 1 year old Macan 4 that wasn't there before. When accelerating, there is the usual lower frequency hum. But under slightly faster acceleration (not even close to aggressive) I now notice a high pitch, scratchy whine. It is not loud, but more of a faint, scratchy jet-engine like sound on top of the regular electric motor sound. It increases in pitch with speed. It also makes the sound when regen-braking. It sounds like it is coming from the front right of the car. I thought it was the accumulation of snow in the tire fender well just rubbing against the tire but I cleaned that out, and the sound is still there. It's a new sound and just started happening a couple of days ago. I doubt the bearings are already going after 6100km! Anyone hear something similar? Could it be that the front electric motor is finally being used more given the snowy/slippery conditions? (Doubt it since I drove this car new in the snow last year).

I get a higher pitch sound under acceleration, but I think it’s only when Sport Sound is on. I felt that I only started noticing it about two months ago.

Thanks for the response! I forgot to mention that my 4 does not have the sport sound option. I will check in the menus to see if it somehow was added/got activated just in case.
