Don't know if you can actually say "soundy" in English but what I mean is this..

Came from a 335 e92 that I had and loved for 10 years. Now, I just bought i slightly used M2 that had 8500 km on it and starting to get used to all the new sounds it makes.

There are like three things I notice that make me react:

- there seems to be no sound dampening what so ever in the rear wheel wells which make me notice how many pebbles and rocks get thrown around in there..

- the snaps/crackle from the gear box when it puts into park or you change from reverse to forward and back.

- sometimes it sounds like something is rolling around in some compartment somewhere from the back but I have nothing at all in any compartment that could do that so I don't know what that could be..

Do any of you guys also notice these things??

Noisy is the word you're looking for. Yes the M2 can be a noisy car but I listen to music always so I don't notice it as much.

This is normal. I can hear every pebble the car kicks up when the radio is off.

You must have DCT. I don't know if that's normal since I have 6MT. My gearbox doesn't clunk or make noise.

Check under your trunk liner to make sure the jack or something else isn't sliding around.

When do you notice this?

Slow speeds?
When turning?
Any incline, like a driveway?

My DCT doesn't make any snap or crackle sounds. Just clunks sometimes, usually if it's cold, but nothing like a snap or crackle.

No rolling around or sliding around sounds.


pebbles/rocks in the brake shields have been known to be very noisy.

You probably have ASD active which makes the car super noisy in sport or sport+. Some of us have either coded it out or installed bypass harnesses.

Check the ASD threads.

Removing ASD is nice, but nothing he describes sounds like an ASD related issue.

[Fedorov]

It's not the ASD I'm talking about, I'm positive about that.

The sound of something rolling around comes mostly at relatively low speeds, quite randomly, and randomly goes away. Sounds like a rock or marble rolling around underneath the backseat.

Any chance of a small rock making its way up somewhere and then falling out..??

Assume you don't have anything in the center console or glove box? It could be a little chestnut or similar type pod that fell in the wiper area and would move around while driving.

You didn't mention your model year, but if it's a 2016/2017 and the noise sounds like 'rocks in a soda can', check the following:
I'm not sure if the 2018 LCI has the improved dust shields.

Doubt it. My 2009 135i had this, my 2014 m235i had this, and my 2017 m3 had this.

[Fedorov]

Well, I would say that this could be it, many of the people writing in that thread describe similar experiences.

Unless the soda can crush noise is the load screeching sound from like a pebble grinding against the brake? Had it on my e92 and stopping and reversing always helped.
Mine is more like a pebble getting thrown around somewhere in the lower back of the car..

I will definitely have a closer look at this later.

check where the battery is?

I must admit the lack of sound deadening from the rear wells was one of the first things I noticed. Coming from a C63 on the same gravel driveway the noise difference is huge. I find myself pulling this face every time I leave the house...

Yup... gravel driveway here too and I pull that exact same face Sounds like a hailstorm of pebbles peppering the bottom of the car.

But if it saved weight, I am OK with it. The car is chubby enough!

[Fedorov]

Haha, the sound of all the pebbles hitting the rear well made me feel sort of naked at first
Not to mention the ear-deafening rumble from driving on bad quality asphalt..
..or the BMW Connected app that seems to have a life of it's own (on android)..

Lol I've just noticed this....ended up removing the damn thing. Opens whenever it wants to.

A recent update most have messed something up. I never had an issue with the connected app before, but now it seems like it's the first thing I see half the time when unlocking my phone.

On top of that, it occasionally decides to be helpful and automatically sets a destination on the nav system (which is silly when the destination is a place I regularly go to).

This has to be the reason, damn jack

My latest ios/idrive update fixed the auto open for the BMW connected app (it no longer does that) but it will now auto play Spotify every time I start the car instead of using the last source of music that was connected (even though the app is closed and does not auto open). Super annoying. I've tried changing the app settings but it doesn't help in my garage as I have a wifi connection there. Guess I have to delete Spotify
