Anyone have this little issue?

So Im driving yesterday with my radio off, just the nav on the split screen was on. I couldnt help but hear a faint ringing sound coming from the dashboard. It would stop and start again. Even my mom noticed it. I know these cars have a ton of modules that constantly run but you shouldnt be able to hear them like that imo.

Any ideas?

Interesting, am I the only one? I guess I'll bring it up to my dealer when I go in.

Was it a ringing sound or more of a high pitched beeping sound that comes and goes? I only ask because I have heard this a couple times in my car, even with the radio on low. I just thought it was the voices in my head making noise but maybe there's actually something to it...

I've heard the high pitched tone several times. Only at low speed as I'm coming home or leaving home. I haven't heard it in a few weeks. I though for a while it was coming from the dash, but then I thought it might be the turbo. 328i, 5200 miles. Have heard it off and on since about 500 miles. Don't have a hard drive and it doesn't sound like any drive I've heard, just a constant high pitch tone.

Yes only at low speeds is when I hear it as well.

No, I havent even tried any disc in the CD/DVD drive, I mainly use my iphone for and sync it to the car for music. Its so annoying.

Probably Bluetooth and wireless phone data noise. Similar to sounds you might hear when you have your phone near a speaker.

Try driving without your phone. I bet the sound disappears.

I once got it when a second person with bluetooth on was in my car
She left the car, I restarted, fixed. The Blackberry was fucking up my iPhone bluetooth.

I'll have to try it, with my phone off. Funny but I haven't heard it since.

No it was in my cup holder. I don't have the cradle in the center console, my phone is just connected via Bluetooth to the stereo.

it is interference between your radio and you phone ! It is constant even when you turn up the radio but the volume of the interference stays the same so that u don't hear it ! if u turn the volume of the radio off then u will hear it on its own !

Have heard this too and did a search on the forum few days ago. I'm glad I'm not going crazy. Its a high pitch constant sound. My only solution is too turn up the volume of my music. Its only distracting if you really pay attention to it with the radio off.

I've noticed the same in my car. Hard to tell where it's coming from other than the general vicinity of the dash. High pitched beep...almost like a very slow version of morse code. Extremely faint. Windows have to be up. Fan is off. Radio is off. Otherwise I can't hear it. It becomes harder to hear at speed. And worst of all, it comes and goes.

I'm equipped with Tech pkg, HK radio. I wonder if its the Nav tracking location? My Toyota nav is constantly spinning the map cd, even when I'm not using guidance.

I thought this was only happening to my car! I don't have any Nav or anything extra inside the car, but I still hear this noise. My car is going in to BMW for it tomorrow and I'll let you know what BMW says about this..

this is how to minimize it: keep your phone away from the radio as far as possible !

I have it too! Though I thinking t it was related to the braking-regen because it seems loudest when coming slowly to a stop.

I have this beep too. This is random sound. I brought in but they don't know where it comes from. I hear this frequently while driving. I am sure this noise comes from front (around engine area). I was lucky to record videos about this noise.

More weird thing is I heard it almost 2 hour passed after parked.

Has anyone brought it to deallership with this issue?

No but I'll let them know next time I go there. I'm sure is just interference of some sort, could be a loud module too.

I just heard this sound for the first time. It is so irritating and drove me nuts. It is like a very faint but a very high-pitched whistle. It comes and goes and can only be heard in slower speeds with everything turned off (radio, climate control, windows up)

Did anyone figure out what this sound is?

EDIT: And yes, to me this is not a "little" issue. I'll sell the car if this can't be fixed!!
