Under the plastic cover in front of the valve cover, I found some parts but I don't know which is the AIR pump. By the part number, can you tell me what they are?

(1) 104 050 0177
(2) 002 5(9?)40 0697 - It's rectangular and there are some tubes going in or out of it. The tubes go to the passenger side of the engine and into two 002 140 0360 which I think are EGR valves.

Can you tell me which one is AIR pump or where to find it if non of them are? Thanks.
