every now and then I get this buzzing from under the dash on the passenger side (sort of where the speaker is) on my s4 vert.
Its very random and really doesnt happen a lot but sometimes it does and it last for about 5 seconds or so. Has anybody ever experienced this....almost sounds like a pump of some sort going on then off.

I know its ahsot in the dark but has anyone experienced this?

 

does it happen when u red line?

 

i used to get it when i had my radiio on with the volume really low. i got it whenever i got incoming cell phone calls.

 

I get that cell phone **** too. I will get a loud beep, beep, beep. It seems to only happen in certain spots or when my friend with a Nokia rides with me.

 

i used to freak out about all the random noises these cars make. then i just learned to ignore them. driving the car became so much more enjoyable after that.

 

^hahahahah ohh man and i thought i was the only one.

 

ive really been ignoring it for the last few years...guess ill continue to do so.
No it is not my redline buzzer, usually happens at lower speeds and seems to happen when my stereo is on too but my stereo is always on.
This sound is VERY random...like i can hear it a couple times in a day and then not hear it again for a solid month or more....ahhh screw it

 

cell phone calls come in on radio waves or some sheeeet like that, i hear it too... on my tv, computer speakers and some other electronic devices with speakers

 

Shitty cell phones cause bad speakers to buzz.
