2000 a4 1.8t secondary air injector incorrect flow need to no what parts to change any help would be great thank you

 

This is what Ross-Tech says:
Possible Causes
* Fuel Pump Relay (J17) faulty
* Hoses/Pipes to/between Components faulty/clogged
* Secondary Air Injection Pump (V101) faulty
* Secondary Air Injection Pump Relay (J299) faulty
* Secondary Air Injection Solenoid Valve (N112) faulty

Possible Solutions
* Check Fuel Pump Relay (J17)
* Check Hoses/Pipes to/between Components
o Check Secondary Air Injection Hoses/Pipes for Carbonization
* Check Secondary Air Injection Pump (V101)
* Check Secondary Air Injection Pump Relay (J299)
* Check Secondary Air Injection Solenoid Valve (N112)

Start by checking the vacuum lines, 4 for 1.8T engine, and if all the lines are ok then move on the what Ross-Tech says.

 

there ended up being a hole in the hose that goes from air pump to another hose or something waiting to see if CEL comes back on thanks for the help

 

Post pictures of the hose that had a hole,please.
