Noise coming from M3

BMWBoss · 01-15-2011, 05:16 PM

I've noticed this weird "rattling" sound coming from my car. It seems like it's coming from the drivetrain. Anytime the car is in neutral I hear it, but then when I sink the clutch (6MT) the noise goes away. I brought the car into my dealer to have them check it out. The service guys said it's completely normal and it's actually called "M chatter". They say the M3's has a tendency to make these random noises. They tested an M3 that they happened to have on the lot for comparison, and it was making the same sound as well. Have any of you experienced this as well? Just want to make sure the dealership isn't jerking me around to avoid paying for any potential repair. I have no error messages from the computer.

Totally normal...... That is just noise from the clutch/flywheel. All manual transmission cars with lightweight flywheels do it.

Light weight flywheel chatter...normal

I have an 08 M3 with the same noise and the dealer said it was normal. They also found the same noise from a customers 09 M3.

I am not concerned.

Thanks guys...I feel a lot better knowing it's 100% normal (despite the fact that it's annoying as hell).

I know what you mean, almost makes it sound like a diesel engine. I was happy to see other ppl had the same noise, now I know its not only me. Dealer said the same thing to me.
