Whining noise when pulling away hard

[Brad_e92]

Hi everyone,

I have recently had my m3 make a whining noise when planting my foot in a straight line in M mode….. it sounded like I had a supercharger lol! (Unfortunately I do not)

Has anyone experienced similar or know what it could be? No noise at all when normally driving about…

I had this and it turned out to be a leaking donut gasket between the headers and cats. Only happened under heavy throttle.

If the whine is from the front and correlates to throttle input, high chance it is this:

Thanks guys, I'll be taking it to the mechanic soon and will mention this to him. It's strange it sounds very mechanical almost like a big motor spinning up lol. Only does it under flat out throttle I was a bit concerned it was the transmission or diff….

I'll put that on my list of future stuff to do. I get that same noise.

Hi Brad_e92,

I'm having the same exact problem and noticed it twice. In my case, I started having that sound after I drove 90mph+ and once it occurred it was consistent even at low acceleration or any acceleration. But it only occurred during acceleration. Have you found a fix for this yet?

Thanks!

power steering fluid low?
