I love my P85 but this annoying rattle near the left side rear view mirror is driving me nuts. Can't enjoy the car as much now with the sound in my head. I took it to the service center twice. The most recent time they took the entire door apart. I thought it had been fixed, but it's still there. Sometimes comes and goes, often with temperature changes. I'm guessing it's some expansion and contraction of plastic parts that cause this, but really have no idea. I live in Southern California, but guessing this isn't just an issue of climate. Any help would be greatly appreciated. Thanks, Kirk
