My check engine light came on 2 days ago. I took it to Autozone and pulled the codes. The first one being P1423=EGI FUNTIONALITY TEST FAILED. The second one being P1411= SAI SYSTEM INCORRECTLY DOWNSTREAM FLOW DETECTED. My car is a 2001 A4 2.8QM. Any help would be greatly appreciated. Thanks.

 

Went to bently site and got P1411 as SEC AIR INJ SYS. BANK 2 FLOW TOO FLOW.
And P1423 as SEC AIR INJ SYS BANK 1 FLOW TOO FLOW.
If anyone knows what that translates to please let me know. Thankyou.
