Has anyone else noticed a periodic noise from the rear axle that sounds a lot like Scooby Doo "Ruh Rho"?

We've had and loved our Taycan 4 CT for three weeks. One problem: This noise periodically comes from the rear. I've tried to determine any sort of consistency, like acceleration, ACC on, etc. If there's a pattern, I can't determine what it might be. It might be related to turning at moderate speed on curvy mountain roads. Any ideas? Thanks in Advance!

I have found 3 sources of noise in my RWD:

1. Turning on seat cooling causes some fan noise from the back
2. My radio was tuned to a static station with white noise. It took me a day to debug this
3. At certain speeds, there is a tiny noise change when the gears are shifting

Are you sure it not the Lane Keeping Assist “wah wah” sound when you cross the lane boundary?

Any possibility it's something you put in the car (cabin or trunk)? EV cars are very quiet, which makes you hear noises you'd never hear in an ICE car. Long ago, when I had my first Tesla, I noticed there was a weird high pitched noise, which at first I thought might have been coming from the car. It took me a bit to figure it out since it only occurred intermittently. It turned out to be a thermos coffee cup, when the air inside cooled (usually after coffee was gone), the pressure inside dropped, and then the air would get sucked in passed the rubber mouth piece making a very high pitched noise (which sounded like an electronics transformer noise). Duh!

I bet that’s it! My A7 would jiggle the steering wheel, which is a better alarm, imho. But I will test the theory out. Thanks so much!
