I have a 2011 C300 4matic with a pano roof. Just noticed significant water collection in the rear passenger footwell. I've searched about all the blog posts on the subject and understand the roof drain issues. Not one of them addresses a pano roof on a W204. Are there any REAR roof drains on this sunroof? You cannot visualize them under the pano roof if they are present. I did try to clear any debris from the front corners. The only thing this car had done to it which may be suspicious is having the front windshield replaced. Any areas of water drain that I missed besides outliers like door panel seals?
