Hey Guys, I'm new here. But I had this problem. Try going to the amp in the rear. Start tugging on the harness that connects to the Amp. Prob solved. Another thing that was happening to me was my driver side speaker would work one day and the next won't. This solved everything. You might need a new amp. Hope this helps..

330i Unusual behavior
Recently bought a 2005 330i, which is in very good condition inside and outside with low mileage. One morning I started the car to go after my business. It started but with an unusual pop pop out of two real speakers while the radio was off. Sound got louder and turned into mimicking a motorcycle. As I drove faster sound became lower and when slowed it got louder. Even while it was parked and engine running same motorcycle race continued. The next day I used a different key, all went normal no motorcycle or any other unusual sounds. Then I switch to my usual key same, nothing unusual happened. Was it a gremlin? I have no clue and still trying to figure out what was cause of that behavior. Any opinion? Love to hear it.

Problem Solved !!!!!!!
!!!!! PROBLEM SOLVED !!!!!
I took the head unit out ( very easy, it takes 2 minutes to get it out). I disconnected all the cables that goes to the unit, reconnect them making sure they seat properly, and buzzing sound was gone instantly. It is worth to try, it only takes 10 minutes and it doesn't cost you anything ( Before you had to dealer and possibly spend some bucks ). Last edited by Semih166; 03-20-2018 at 05:35 PM..

alert gong is really loud since replacing head unit...
I had the buzzing problem for a couple of years. finally could not stand it and bought a replacement head unit from reputable reseller. installed by a super high-end audio place. it cured the buzzing, but now the chime for unfastened seat-belts and other alerts is incredibly loud.
can this be reprogrammed to make it softer? help? John |

Most likely you got a Head unit programmed for the base system
stereo setup and you have the Hi Fi setup. The head unit needs to be reprogrammed for Hi Fi . You need to verify this by printing out your options list from one of the free online Vin checkers or you could look for the amp in the Driver side rear wheel Well. (US driver side) The option for Hi Fi is 676. How can you have a 2011 330 when the only US version in a e90 is 06 |

I've been meaning to post this for like a year. So yes, this speaking buzzing issue is caused by the head unit, which does need to be replaced to completely resolve the issue (at least this is what i was told by a bmw mechanic).
The buzzing happens at different intensities and sometimes goes away (after hitting a pothole maybe) which led me to believe it's some kind of loose connection. I just read a post above me about reseating the wires at the back of the head unit, which I haven't tried and probably should. My quickfix was this.. after learning it was a head unit issue I tried just giving a swift judo chop to the side of the center panel and the buzz went away. Of course it eventually comes back but that completely gets rid of the noise for me for now when it's unbearable, and I have to do it once a week or so maybe. Not sure if I'm causing damage or anything but just saying, if you really aren't trying to swap out your unit and you find this issue as annoying as me, it's one possible option? Maybe one day it won't work but it's been working for months so far. To clarify.. I'm just reaching down where the passenger's legs would be and just hitting the right side of the center console, around where i think the head unit is.

I have a 2008 328i Coupe with the same problem with my drivers door speaker. I think I'm doing what everyone else said to do, plus replace the radio with an aftermarket one with more features. Like GPS, and back up camera. What do you guys think?

I followed advice here, removed climate control unit, unscrewed head unit, unplugged connector and replugged, noise gone.
Thanks to the nice folk here. |

I had the speaker buzz two times, in 2012 and 2019
Both time of the buzz sound from rear speaker stopped by itself after being locked and rested for awhile (I checked a few hours later and the buzz sound is gone). as many said, the symptom is that the sound start from nowhere, volume cannot be controlled by tuning in radio volume etc, sound does not stop when turn off radio. shut off engine and lock the door does not make the buzz sound go away. but after a few hours when I check again, the buzz sound is gone and never comes back.
Maybe I am lucky, just want to post my experience for your reference. |

We know why the sound stays on if you read this thread you would to.
The car uses the stereo for alarms and reminders. When you unlock the car the car wakes up and although the screen on the stereo is off it's still really on . There is a timeout after you leave the car before it goes to sleep and powers everything down. |

BMW 320D 2010 When I put the key into the ignition I can hear a constant noise from front passenger door speaker, when the radio is on this sound doesn't stop and sometimes buzzing noise from radio, upon turning the car off and I remove the key I can hear a sound for about a minute then stop. Need a software re-flash? What can this be and how to resolve this? Many thanks Last edited by B2021; 02-23-2021 at 02:59 PM.. |
