I had the the tin can noise as well (February Build). This was the same day, just after I had some sort of shims replaced on my front wheel area (between rotor and hub - it was hitting the brake shields).
Now, what is funny is I heard "the new noise" coming from the rear and knew it was what the F80/82/83 crowd heard as rocks getting stuck in the brake shield. The video directly below was my first issue with a noise, which sounds nothing like the other two videos and was corrected after those shims were replaced (apparently there is a service bulletin out on this issue as well): This is what I heard from the rear or otherwise known as "Rock in brake shield" M3/M4 Videos below: |

The ramble noise we are referring to, is significantly different. It's a brief metallic grinding/rambling/cluttering noise. Happens at random and lasts less than a second or so. Always from underneath the car, rear end. Hard to describe how it sounds: as if you got a metallic lunchbox with a fork or knife inside, and you're briefly somehow shaking it sideways: some metal-against-metal rubbing/screeching. If you hear it for the very first time, it startles you as you immediately think that something screwed up. But after a couple of times, you kinda 'get used to it' (similar sound) + no impact on driving. Just a nuisance, except if it turns out to be some car internals (rear differential ?) progressively getting damaged (which we don't know, as we speak).

"I already had several times a rambling noise, as if I drive over a Cola can or something alike. I personally noticed it, for example when I drive at low speed with open windows through the city. Pedestrians looked back, startled, as if I had driven over something, though I hadn't. I cannot yet pinpoint this, as I don't know where it comes from. I cannot provoke this noise. Happens with cold and warm [engine] circumstances. Has anyone an idea ?"

Following this I started hearing transmission chatter when idle. It is like a flywheel chatter. Goes away when clutch is engaged or at higher idle -- As in you can head the noise disappear. The chatter was not there on day one (I'm sure because I would not have accepted delivery if I heard this noise in the quiet delivery room). Also it's quieter or louder at times. BMW AU changed the clutch but the chatter was still there. I did suggest to them at the onset that the flywheel needs to be looked at. It like a broken spring Center flywheel. But they insisted clutch. Eventually I was told that the loud transmission chatter noise is normal if mdct. BMW AU also pointed me to the manual that says mechanical engagement noises are common -- I said this is a chatter not mechanical engagement noises. Honestly, I can tell the difference between an engagement noise which I think is a form of engineered art versus a chatter. Overall it sounds like marbles in a tin -- not that loud but obviously noticeable in the cabin. Let's just say I wouldn't drive without music in the background. Pretty disappointing for a rather expensive German car in AU. BMW AU seems to think it's ok hence little effort in continuation. I've also run out of motivation to convince them - I do have other better things to do. I'm just living with it. Waiting for more community feedback. Apart from this tin can transmission, I do love the M2.

Much like the HPFP and wastegate issues on my previous n54 motor, there seems to be a difference between BMWNA and AU support. I need something concrete to stand on and present to BMW AU.

I just got notified from my dealer that the parts will be in on Wednesday for the recall. Much sooner than I anticipated. For those of us who already took delivery, they are doing an auto-ship to the selling dealer.
