High-pitched whine on acceleration? (No s/c)

BIMMERPOST
     Featured on BIMMERPOST.com
Last Tuesday I started noticing a really high-pitched whine when I accelerate. It comes on above 3k RPM and stays until I go back down in the rev range. The harder I accelerate, the louder it is. It honest to God sounds like I have a supercharger installed. It sounds a lot like the video clips I've heard of the Harrop kit or the people with solid/delrin differential bushings.

Dealership said they don't know what it is. Anyone have any idea?

Does it sound like it's coming from infront of you? Or next/behind you? If it's from the front I would check the air box to make sure it has a tight seal.

Thats your blower motor probably. Change the speed of the fan see if the noise pitch changes.

It could be low power steering fluid level. I'd try topping it off and see if that helps (you can pick up the Pentosin fluid at Oreilly, AutoZone, etc.).

I had the same sort of noise and that's what it ended up being, unfortunately I don't have a video of the sound. Good luck!

Mine ended up being my tensioner pulley, it was a little loose. I didn't discover this until I put my blower on, so there's a different kind of whine now haha

+1 on this. Pop the cap open when it cold and check the level.

Hard to tell, but I believe coming from in front. I will check the airbox to make sure it's tight.

Nope. Nothing like that. I sounds a lot like the sound in this video at 0:19:

Thanks for this. How did you tighten it?

Thanks for commenting guys. Man, I would love for it to be something as simple as that. I don't see anything that appears to be a dipstick for the power steering fluid. How can you tell if it is low? How much is supposed to be in there? Also, do you have a link to the exact fluid I need? Thanks!

I honestly just eyeballed it. Not sure of the exact amount but it's cheap enough that you could just pick up a bottle and add a little at a time so you don't over fill it. I believe if you over fill it, it will just leak out of the reservoir a little bit. This happens at the track too when the fluid heats up and it is meant to "vent" out this way. I have a microfiber towel ziptied around the cap for this reason. Let us know how it goes!

On the power steering fluid cap look on the thing sticking down. there are two notchs/levels. the top notch is the full and the lower notch is the minimum. just take off the cap, wipe off the stick, gently screw it back on a remove and see where the wet line is.
