Annoying rattles in cabin
 

Anyone else had this issue and know what it might be?

When I'm driving at highway speeds, there seems to be some high pitched rattling or squeaking sound that's incredibly similar to crickets chirping. It doesn't happen below 25 MPH. Sounds like it's coming from the passenger side.

Any help/ideas on this would be appreciated as it's starting to drive me crazy.

I had the same thing going on for a while and found that if I completely empty out my glove compartment the noise went away. I use to carry a flashlight and a multitool in there, with the vibration it might have been rattling. Just a thought.

I thought maybe the same thing, but I only have some documents in there, no tools or the like.

Check and see if the passenger head rest is rubbing the roof. Also check the passenger side seatbelt. If all else fails, get a louder exhaust.

Does it happen with the window open or closed or partially open?

It's happening at least in the cases of fully closed and partially open. Haven't tested it fully open; will do tomorrow morning on my commute.

Testing with passenger-side window open is not needed if the noise was there with windows closed. It was a question to see if wind turbulence was a factor. On some of my cars, heavy wind flowing on the passenger-side seat belt causes a fluttering akin to cricket noise.

Also, check tires for debris embedded in the tread and thickness of brake pads.

need to change handle to POS Z

Check the seal at the bottom of the door jam. The seal on my drivers side was creating a squeaking/cricket sound while driving.

Might help to take a passenger along to listen.

Sounds like it's coming from behind the dash, but I'll check the seal too.

I'll be taking the glove box out to add a cabin filter soon, so I'll take a look when I do that. Thought the same thing about getting a passenger to help out.

You can also check the speaker in the door on that side, sometimes it could be a loose speaker that creates the rattling noise

I had the same thing took it ro the dealer and they said it was comming from ac. But that they wernt sure. It would start ticking everytime i hit 4k rpms.
It went away after a couple of days. Hasnt come back

I'm having a similar issue: A rattling sound when the car is at speed. Sounds like it's coming from the left, front side. I checked the air vent (both in the dash and on the door), left side of the instrument cluster, A pillar, front speaker, and put the window down then back up. Nothing felt loose and manipulating the window didn't seem to matter. Any thoughts? I'll continue to look things over myself and see if I can find anything that could be causing this annoyance.

I've had what sounds similar to this. It ended up being the pass seat belt receiver. When it is sticking straight up, something inside makes noise, but if you push it forward and kind of wedge it between the seat and center console, the noise stops. Hopefully this takes care of it for you as well.

Update -

I took a look at nearly everything on the left, front side of the cabin and could not find anything that appeared loose. So, I'm baffled as to how this noise persists. It's not always there, but when it is, it's annoying. My most recent suspicion: Maybe the wind outside is causing a rattle/fluttering noise that sounds like a rattle as it passes over the driver side rearview mirror?

Thoughts?

Took it to the dealer finally and they figured out what was wrong. The aftermarket battery that was installed by the BMW dealer that sold me the car was not properly being held down, and was moving around a bit, causing the cricket sounds.

What blows the most about it is that they had to add a couple washers to hold it down, and didn't cover that under warranty, charging me a half-hour of labor due to the fact it was the BMW dealership who did it. I went to that dealer, and they refused absolutely to cover the cost (about $57) even though they had performed the work that caused the issue.

At least it's fixed now.

EDIT: fixing my fat fingers.

Had similar sound coming from right side of dash. Finally decided it was from glove box but after I emptied glove box had the same noise. Finally I left glove box open and drove and guess what? No noise!
Apparently the latch itself is making noise. Haven't fixed it yet but should be pretty simple fix.

Derp.
Think I figured it out, and don't know why I didn't think of this earlier. I think the rattling sounds are coming from the windows. Since they're kinda just up and not braced all that much against the car frame at the top, they rattle a little bit at higher speeds. Was hard to determine since the Z doesn't exactly have the greatest sound damping in it as stock.
While I was driving home the other night, I noticed the rattle again. But also realized that it was coming from the passenger side too. Was hard to pick up on that, since the road noise was making it hard to hear from that side of the car.

I have the same problem except it's at all speed ranges.

The weird thing is it goes away when my wife is not in the car...

Solution: dont take the wife...genious I am:facepalm:
