Part number for windshield moulding? What is this?

As you can see, the moulding along the bottom of my windshield is cracking apart from the sun. It no longer protects what's under it from rain, etc. and I clearly need to fix it.



I talked to a windshield company today which claimed that it was the entire piece from BMW that needs to be replaced, not just some caulk or something.



So what I need is the part number for that entire piece that starts underneath the windshield wipers and runs all the way up to the windshield. I checked realoem, but couldn't find it.



Sorry about the dark pictures
