Electronic Humming? - BMW 3-Series (E90 E92) Forum

Sara504 · 04-21-2009, 03:16 PM

I searched "humming" and didnt find a thread about this, If I'm wrong just post a link.

I noticed today (again) that there was high pitched electronic humming noise coming from the stero, AC control compartment in my car. I turned my music off. Still humming. I took the CD out of the player because I thought maybe it was something with the disc, nope still humming. I turned the A/C off. Still humming. It was only when I parked and turned off my car did the noise finally stop. It did this yesterday as well. These are the first two times in 5 months that this has happened. Any ideas?

My car occasionally does the same thing. The sounds seems to be coming from either the CD player or DVD player. The humming stops after a few minutes. I haven't figured out any rhyme or reason when it hums and when it does not hum.

It did again when I started my car to go to work, but quit a minute later. It did not hum on the way home.. I'm bringing it by the dealership cause its annoying.

Found out what it was. Its the "E-BOX" It's doing its job but being loud about it so they ordered a part and will replace it free.
