Object rolling around inside cabin?
Hi all, I just picked up a 2015 m235i a week ago and I'm excited to join this club!
I've been enjoying the car, but noticed this sound while driving slowly around parking lots that's been driving me crazy. The only way I can describe it is that it's like a round object is rolling around a plastic surface somewhere inside the cabin. For example, if I stop suddenly while driving in a parking lot, the rolling sound will begin and continue for several seconds after the car has come to a complete stop, when the object eventually loses momentum. I've completely emptied out the cabin but the noise still continues, so I have no idea where it could even possibly be coming from. It sounds like it might be coming from the rear, but it's hard to place since it's very quiet. The only solution I see is to rip out all the interior trim and hope I find a stray bolt somewhere. I might be on my own for this one, but I'm posting this in case anyone has had a similar problem and might be able to direct me on where to look first Thanks in advance for your help!

It could be something in the plastic floor vents under the front seats. The opening is in the rear footwell. Happy hunting!

You've got to localize the sound. Have someone sit in the pass seat, fold the seat back, stick their head by the back seats, while you do what you need to do to make the noise. See if its coming from the back or front of the car, right or left side.
I'd even have someone lay in the trunk and hopefully you can do what you do at low speeds to make the noise. |

Sound travels, so it's going to be hard to find it... You'll need someone else to drive the car and let you listen and try to pin point it's location. Front, rear, top or bottom, then you'll maybe be able to try and see what's up. Could be anything! Something in the roof, vents, underside. I had one car where those little Chipmunks took some nuts inside my hood, in the little holes of the structure/frame and it made noise too, but I had to pick them out one by one, over time! Or I could have taken to hood off and tilted it to get them. Point is ... It's not fun! Hahahaha
Good Luck |

Update: there was a loose screw in the vent in the footwell John mentioned. Who knows where the screw came from, but I'll ignore that for now.
Thanks for the help! I literally would never have guessed there were vents under the front seats- It seems like their main functional purpose is to attract crap that will rattle around and make noise. |
