Reviving a very old thread.
Which is the fuse for the secondary air injection pump? I can’t find it on the list in the handbook

EDIT: There is also a relay for it. It's position #4 in the second image of the relay panel in the electronics box in the plenum chamber.

Well, instead of seeking out the fuse, I used the VCDS and ran the pump. I could hear the relay clicking and the pump running in the air filter box, so I assume that’s all working.
