Dash rattle

I have a very annoying dash rattle on the passengers side close to the right-most vent. It sounds similar to if a ping pong ball was rattling around in there. Has anyone had a similar issue or know where to start looking before I tear the dash apart to find it?

Check your glove compartment for something loose.

I've checked that, only the manual in there. It sounds higher up though, like by the vent.

Iíve taken apart my dash looking for rattles. My advice: turn up the radio or lower the windows.

I would honestly just live with it. Taking the car apart for rattles would most likely...cause more rattles.

Good advice. I was hoping for a quick fix, but those aren't very common haha. Thanks

Check to make sure the screws are tightened on the glove box. Found a couple that needed some work on my own.

You might have to get used to it. The price you pay for having bolted rear subframe.
I had a rattle coming from my center console next to my right leg, but I found that by folding up a paper towel and sticking it in between the console and car, that it relented.
You might try feeling around various places in the area of your rattle, and see if it gives you relief from the rattle. At that point you can decide whether there is a strategy you can employ to stop the rattle.

My whole car rattles. I never noticed it until I started reading all these posts on the forum. Now I just live with it, but I don't understand how my wife's Merc has not one rattle, but both my M's rattle like crazy. Quality control needs to step their game up.

My C43 interior rattles like crazy. Center console, covers near gas pedal, panoramic sunroof... a symptom of tight suspension I guess.

Use felt tape. If your car is under warranty, take it to a dealer. They first lined my door panels and it fixed it. I just took it in this week for the center dash rattle as well. They lined with felt tape. Now I car hear the rear panels. LOL. Shouldn't have this with a 80k dollar car. So, make the dealer do for free if still under warranty. If they break any tabs, they just install new panels.

Properly done, taking the car apart to repair rattles will not result in more. Iíve used nearly 70 feet of felt tape fixing both of my F80 M3s. My Ď18 is still not perfectly silent, but the rear subframe mounting and my coil over setup are going to transmit a lot of vibration into the body.

The rattle that OP is hearing is often the sticky door gasket that is well known to creak. Iíd take a drive with someone else behind the wheel to isolate the source.

If the door is creaking, would start by applying gummi pflege to the seal or applying Teflon tape to the structure where the seal contacts.

If that doesnít fix it, pulling the large trim piece out of the dash requires no tools and will grant access to the passenger vent (on LHD cars).

Rattles are part of what make expensive cars unique

I feel like trying to fix rattles becomes a bottomless pit of frustration. They tend to come back. Unless, it is the infamous door rattle on the M3. I did get that fixed through the dealer under warranty and it hasn't been an issue since

You should take the car to the dealer and have them drive around a few uneven patches of road with you. They will figure out where the issue is. Then, you can just fix it on your own if you like

I suspect itís the passenger side door lock pin. My dealer added felt tape, and the rattle disappeared... for a month. Now Iím just going to fix it myself.
