Last month I purchased my first BMW, and so far it's been a wonderful experience up until last week. Out of the clear blue I started to hear static type noise which appears to be coming out of the passenger tweeter. The static isn't always there, but it seems that once my car goes over bumpy roads or gets up to 60+ MPH on the freeway, it rears it's ugly head. It seems to be only coming from one speaker and is present whether when the volume is turned down or sound system is off.
The car has the standard HiFI 9 speaker system. If anyone has any thoughts of what else it could be or how I can go about fixing / addressing it with the dealership that would be great. I've got an appointment coming up with the dealer and I've emailed them a longer version of the video as well. Thanks much.
