One Fault Code Down 1 To Go!!!!!!

Had the infamous 17705 fault code last week, so took the advice from the guys on here and cleaned the throttle body at the weekend:). Instantly felt better and smoother even though it wasnt that dirty!

Hooked the car upto my mates vag-com and "1 fault found 16795 - secondary air injection system: incorrect flow detected":mad: I have searched the forum and there are posts on what could be the problem but i need to find out where/what this "secondary air injection system is"?

Also a picture of where it is would help as im not machanicly minded so havent got a clue what everything is under the bonnett.

Cheers:thumbup:
