Hello,
This E90 323i speakers have constant noise coming,
This speaker noise does not change with volume up or down from radio.
Speaker noise starts right away when i put ignition key in and stays there irrespective of Engine on/off
Noise goes off automatically 2-3minutes after I take ignition key out.
Please play check audio I recorded coming out from speakers. I put phone microphone right on the top of speaker.
Everything is stock on this car, Radio, speakers etc, Nothing is modded.

Sounds like electrical interference from another electronic device in the car.
Usually when i am trying to solve NOISE. I check and clean grounding points for the radio system.
Possible some wires are running on top of your speaker wires emitted noise into the speaker wire.
I re-connected the radio wiring and the noise is gone permanently, but sometime aux is not working

Check the male pins and female sockets in the connectors to see if they are in good condition.
