Cross posted on my blog with more pictures. I made an unexpected discovery today. We have had an unexpectedly dry and warm February, and today on the first of March will hit 70 degrees Fahrenheit. I decided to open the Panoramic roof. I have noticed two areas of very minor noise in my car. One sounded like a radio buzz that showed up very infrequently the first week but has since subsided completely. The second noise was a wee tiny rattle on the Panoramic roof. I wasn't hearing the noise but decided to feel around for anything loose. Surprisingly I discovered that the roof has a little screen in the front that comes up when open. When you are driving you can put your hand up there and push the contraption down quite easily. I am guessing the screen is to keep dirt away from the car? Or perhaps to aid aerodynamics? Not really sure. Anyone know?
