I brought my 2022 X4MC to the dealer due to a rattle noise that was coming from the driver side door tweeter speaker. The rattle would only be there with the exhaust button turned on. The dealer ordered parts to replace the speaker and installed the new parts yesterday. Unfortunately, it sounds like that didn't fix the issue.

I used the Bimmercode app to turn off the Active Sound, which actually fixed the rattle noise. I also did not notice a drop in engine or exhaust noise after I turned off the Active Sound. This makes me think that the Active Sound has been broken since I got the car and it never really worked.

Am I able to tell the dealer that I used the Bimmercode app to turn off the Active Sound without voiding any warranties, and is this a fixable issue?
