Not enough information to assist you. What engine do you have, have you scanned the ECM, what is the DTC(s) that telling you it is the secondary air system, etc.?

Combination valve for Secondary Air Injection (AIR), checking function and for proper seal.

Most likely the secondary air injection system cleaning is needed. I would contact local Audi dealer first about the service. It might be still under emission warranty.

Emissions warranty for all vehicles sold in USA is 8 years/80K miles, whichever occurs first. Since the AIR system is part of the emissions system, you should be covered (unless you exceed the mileage limit), and have your Audi dealer repair the system.
