High pitch noise inside vehicle
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\\\'s on, and it\\\'s not.
Anybody else have this noise inside their cabin? |

The other issue might be what some of us have experienced on here with the power steering pump. Try seeing if you can change the pitch of the sound by turning the wheel, if so its your pump. My bet though is the rear fan control. |

I had this in my 07 335i back in 2007-2008. It got so bad and wouldn't go away and dealer was unable to diagnose. BMWNA took over couldn't fix it, just gutted the car of all electronics and replaced everything in lieu of buying back the car for this and many other issues. Am shocked this is still happening to cars 4yrs newer!

Mine is is making the same noise, and I think it has to do with the rear fan, is this a simple fix, or should the dealer fix this?

Ive never brought it up to the dealer because I dont want them ripping apart the console and then putting it back together with the possibility of rattle. The kids don;t use it much so basically if its off I don't hear it.

I have the same exact issue with my brand new 12 x5M.
Random, not on every start up, not dependent with radio,hvac,or sunroof tilt. Will ck the rear climate control and see. It sounds like it's coming from the engine bay area, does happen more often after warmup than cold. |

Turning off the rear HVAC does not help, still makes the same high pitch noise. It seems the noise only happens after the car is parked after driven when hot.
One other weird incident today. Got into the car after it has been parked for about 1 hour, had the temp set at 60 degree no A/C. Outside temp was about 64, nothing but hot air came out of the vents. At first I thought it was just because the car was parked in the sun, the fan was set on 2nd bar and then all the sudden for a brief second the fan went to full blast, blasting hot air into the car and then went back to normal 2 bar setting. (At the time when it was full blasting the light on the fan bar didn't change). And then cold air started coming out of the vents (from outside). Weird... |
