Yep I did those 2 vac caps this spring, along with the 2 pieces of vac hose next to the ports with that white thing in the middle - and the entire SAP line from the passenger side of the manifold that ends on the "3rd port" that no arrow is pointing to, in your pic - the entire line is avail from BMW for $19 or so and has the 2 proper vac hose sections and a new hard line which is in the middle
