Engine "readiness"

[bikefright]

I have two "failed/incomplete" items listed under engine readiness:

Oxygen Sensor
Secondary Air Injection

What on earth is the second item??

A guess: 2nd one could be something to do with AGR.

Thanks icenutter - i've updated my post as I'd made some important mistakes in the post, maybe this might help diagnosis. I've added VAG-COM output too.

Just found a PDF here, I know it'f for a TT, but the principal is most likely the same:

This links my Secondary Air Injection issue with the Warm Up Catalyst.

I'm going to check all my vacuum hoses at first as the car has just had a sevice at a stealership.......
