The rubber seal is part #51237161345 and located in https://www.realoem.com/bmw/enUS/sho...diagId=41_1747 as item 21 in the diagram. As has been mentioned, your's doesn't look bad in your pictures but we don't see the whole thing. However your one picture does make it look like the bulkhead plastic piece is broken on the drivers side.


Hope this helps
