High frequency sound coming out ac area?? HELP???
Just wondering if others have the same noise. I get a very high pitch, radio signaly sound, when I first start my car. It disappears after a few minutes but it sounds as though my radio... but it isnt. Its like a high pitch mic sound or some it comes for 15 seconds and only on startup???
Has anyone else noticed? Took to bmw and they checked all..... Couldnt find an issue... got car back it does it sometimes and sometimes it doesnt I relized with ac off, radio on 0 volume, no ac on just car on ... if you have a1 ears and put ur ear close to the digital ac temp lcd u can hear it lower... which is on and u hear it maybe itd the electronical system in the car or maybe its mine.... does anyone have same noise.... if someone can try it would be appericiated... here is 2 videos.... https://streamable.com/g1la7x https://streamable.com/37gt1p |

Yep, I have it too and it also audible while driving. Not just the first 15 mins. Im super sensitive to high pitched sounds. My GF and other passengers can't hear it.
The one thing I can tell you is when I did the OTA update the other day, I sat in the car while it was completing and there 100% is a computer with a heatsink AND fan behind the AC digital temp lcd. The fan was on and blowing loud when the system was installing the remote update. So the noise may be that fan or computer having coil whine. |

If I rest my fingers on the LCD display, the stop pretty much does away since Im blocking the direction of the sound. These high freq sounds are very narrow and weak, so easily blocked and avoided by turning you head. If I drive with my head pointed forward I hear it. If i turn to the right or left, the sound goes away. Freaky. |

The noise, for me, is 100% from behind the HVAC screen. I can put a huge folder infront of the screen and move it back and forth- the sound will fade in and fade out since the folder blocks it. |

Yes, is 100% positional. I still heard it today in certain positions quite easily.

Which motor do you have? I don't believe this is an option on the 40i. From what I understand it doesn't have fake sound like the 45e and 50i
