Car trouble with vag com info

So im sitting in my audi on my oobdtool.com version of vag com reading a check engine light. Yall help me out with whats going on and what to check with vag com (this is my first time using it), and how to go about fixing it.

1 Fault Found:
16795 - Secondary Air Injection System: Incorrect Flow Detected
P0411 - 002 - Lower Limit Exceeded

I then began to search around and click on the readiness tab and found all of the following to be "failed or incomplete:"
oxygen sensor heating
oxygen sensor(s)
secondary air injection
evaporative emissions
catalytic converter(s)

So whats going on here? The car is running a little worse than usual but not terrible, i do seem to get lower mpg numbers than others that have posted in the mpg threads, somethings wrong, what could it be??
