As to these rubber "drains" located in the wheel wells, I always thought of them as vents, but I suppose they double as both.

But this doesn't address the reason why calphil is getting water in his trunk in the first place.

The reason I reply is because i'm also getting water in my 300E trunk, and always at the same location: in the wheel wells presumably through those vented rubber grommets located underneath the trunk liner in the wells.

Is this normal? I've checked the sunroof drain tubes and they're fine, as well as the tailight assembly gasket/seals, and the trunk seal itself. All are ok. The body-formed drains that the grommets attach to have deteriorated somewhat, leading me to believe that the deterioration allows water to enter (less height to enter trunk). Anyone else have this problem?

Also, the water only enters trunk after driving in rainy conditions --I can hose water on my trunk all day long and it will remain dry.
