Sunroof

[jtrevill]

Have about 1100 miles on my 328i, but mostly drive at night. Today I was outside in the sunlight and noticed a black smudge forming in the middle of the sunroof cover. It runs from the back toward the mirror, but not all the way forward. Its about 1/2 inch wide, and appears to be rubbing on something inside the roof. Because I drive at night, I frequently open it. Anyone else seeing this?

Could it be something leaking? Is it on the underside?

sounds like some grease got on the glass. clean and see if it comes back.

Or take it to the dealer. (oh how I'd hate to be a service person @ a BMW DLR)
