can't get speaker cover off

thanks for the dyi suggestion. I think I have the same problem. However I am having trouble taking off the speaker cover. Can you provide a bit more detail on that step? I'm afraid to cause damage. I am leasing the car and it's only 1 month old but I already noticed the buzzing/rattling noise from that area at high engine rpms.

Can’t get cover off

Step 1: I found that the cover wasn't easy to just lift up. The speaker cover has 6 clips as shown in the pic below. I used a card to wedge under the speaker cover and to push each clip in. I started with the bottom left clip (closest to steering wheel) I found that I had to push the card into the clip in order to release it and simultaneously lift the cover with a little force. Eventually one at a time, I released all 6 clips. It could be that you can just lift up the cover with pressure but it didn't feel to me as if it would work without breaking the cover



Step 2: Once I lifted the cover off I used felt tape to cover the plastic tab on the top of the speaker cover as shown in the picture below:


Step 3: I then covered those two plastic contact points by the speaker on the sides of where the plastic tab from the speaker cover connects to pictured below:


I then popped the speaker cover back in and now the rattle has gone away. I tested it in Sport+ mode under heavy acceleration and when raising the volume of the stereo under different frequencies.

This is a link to the felt tape I used:

Hi, thanks for the detailed solution. However, I’m not able to get the cover off. Can you post more detail as to how you removed it?

Removing the cover was harder than I expected. Took 45 mins trying to push each clip in and lift. I tried the basic trim tools but they were too thick to get it to the right spot for me. I ended up snipping an inch off an expired credit card, locating the clip, and jamming it in at ~ 45deg angle. I bent 1/3 of the back of the card to get better grip.

It did fix my rattling that would occur at 1.5k, 3k rpm. Seemed to vary depending on what kind of music and how loud I was playing.

Same issue as some other owners - dealer couldn’t find the problem either and just adjusted treble and bass settings.

Applied the felt and refitted cover and rattle has now gone. For any UK owners, the tape and tools I used are linked below:

Awesome! Thanks for the detailed instructions!! Just did it on mine, but used foam tape instead because that's all I had at the moment. It's a lot thicker and can absorb more so I'm hoping it'll do just fine. Thanks again!

Thank You!

Thank you for the excellent step by step instructions. I thought I had a blown speaker and was going to take my new car to the BMW dealer. I am so glad I found your post. I did use a 45 degree angle slim trim tool and your pictures to pop the speaker cover. I did use self stick velcro tape (soft side) and this worked perfectly. The entire job took last than 10 minutes and likely saved me big bucks. I love this car and now no more rattles. Awesome.

Great post. You would think BMW and their dealers were onto these types of issue.

I actually had my speakers replaced and did the fix realizing later that it was simply rattles. SMH.

Just adding my voice to the thank yous. This worked perfectly to solve the rattle. Getting those clips to release was the trickiest part!

Although I had exactly the same issue on my previous MB E43 AMG built in Burmester HiFi , I have never thought doing it on the actual G20. It seems to be a "central speaker curse" as my ex F10 B&O central speaker was falling when road quality not too good.
On the G20 the job was done only by using the "recommended" card , panel removed in 5 minutes (if you can be accurate in regards to the clips locations from the above pics).
Thank you very much gnr4all !

Just completed this modification. However, I realized the felt I bought was too thick. While I had the cover off I just tried electrical tape, and I can verify it works too.


Thanks to the OP!
