Default CEL : improper airflow SAP

2000 Audi a4 Avant 1.8t - 140,000 miles

Ok So several months ago I had to replace my front end

SAP
Support
Rad
Condessor
Bumper
Ac lines

Never before did I have this CEL.....Now I have it...Im stumped on why

SAP is hard wired in and working/turns on

None of its lines are blocked/clogged
Egr was removed and cleaned out
I did not find any vac leaks so far


Please can anyone give me tips? Walk me through trial/error to find the issue?

Will any Combi valve work for my 1.8t?

Ok so I have swapped out the Combi Valve...replaced the Secondary air pump.......Checked to see if the pump actually works.....run the car for three days with no check engine lights....and BOOM! Check engine light for incorrect air flow - Secondary Air Injection...... - .- ......WTF!!!! I am so confused. Does anyone have an stock ECU flash that eliminates emissions ? Im Fed up!!!...I am two months over due for inspection and I can not get it inspected with a CEL!!! HEEELPP PLEASE!!
