After enduring a few days of noises from my panorama sunroof, and questioning MB's quality for producing such a noisy roof. I fixed it!!!<br><br>
<br><br>
First of all, on my car, it was not a creaking but a squeaky sound, only when the sunroof was closed. I just opened the sunroof in the vent position and put ARMOR-ALL on the back and side rubber seal that is attached to the car (not the glass lid) and voila! absolutely no more noises. Hope it lasts and mercedes comes up with an adequate lubricant for the mentioned seal.
