Annoying buzz sound coming from inside of the car

Hello

2011 E90 M3 with 76K on the odometer.

Problem free, but I have had this annoying buzzing sound coming from inside the car since I Purchased the car 3 years ago. Sounds like its coming from the rear of the car.

It only comes on when the key is inside the car and the car does not have to be turned on.

Any info is appreciated.

Buzz? is it audio buzz?

I don't have buzz but I do have interior panels vibrating when I turn up the bass when I listen to music.

Try to get a recording of it.

The only in my ears typical buzz noise I'm aware of is the brake vaccum pump. Thats on the left side engine bay/fender though. Fuel pump?
