I don't know what your exact model is, but from the 3 series diagram, it appears you have to replace the whole sensor, assuming that's where the leak is coming from. It is part number 8 here. Your other option would be to check out the o-ring size on the level sensor and get a new one, but BMW does not offer that as a separate part.
