I have a new noise from my car. It can only be heard when applying throttle and when I let off the throttle in any gear. The closest thing I can equate it to would be metal tensioning up. I know it sounds strange but I am preparing to do a 1500 mile trip at the end of April so I need to be sure my clutch won't fail. From what I've read it doesn't sound like a pilot bearing or anything of the like. My guess would be a broken spring on the friction plate?? I may try to take a video in the near future but I feel that it is quiet enough my phone will not pick up the sound. TIA

Nothing about those symptoms sounds directly related to the clutch to me. Could be a lot of things, there are many more probable causes.

What would be your guess at what it is if it's not the clutch?

A diff can make a whining noise on acceleration and deceleration. The other thing to look at would be the driveshaft u-joints.
Be sure and check the fluid levels in the trans, and diff.

Here is a video link! You may have to turn it up to hear the noise but I did it enough that I think it is noticeable. https://youtu.be/2NA3CZHLwHQ

You can easily create the sound when driving. What if you park the car and rev it out of gear do you have the same noise?

No, I do not. Only when under load.Originally Posted by RobertDenali

Based on that get the car up in the air and check the drivetrain and differential.

I bit the bullet and took it to the dealer. I just didn't have the time to chase this down. They determined it was the diff carrier being rusted out. Good thing I'm getting a full M3 rear end in the near future!
