Got my car back from the dealer now, and they ordered 2x new midrange speakers for the front doors. I hope that will fix the problem. Too bad the delivery time was about 1 week. Every time i use the BT handsfree, the midrange speakers make a terrible noise. So i have to use my handset to make calls.
