2017 Octavia RS Got a faint crackle coming from my left mic in the unit on the ceiling (the one with the sunglasses holder and lights). Its only the left of the two mics which this is happening with. I can barely hear it but it sounds like a really faint buzzing fly. When I make calls from the car the person on the other end of the phone can hear it much louder, like a wooden spoon running back and forth on a cheese grater. The crackle stops when I move and then starts a few moments later. Its like it senses body movement. I'm assuming I'll need to replace it. Looks easy enough, a tiny component with just two small connections to solder. Problem is for the life of me I can't find the part anywhere, including these forums. I've turned the Internet upside down looking for it. Anyone have any clues?
