Some codes (and hopefully) advice

[TopBear]

Had a new (2nd hand) RS4 SAI pump fitted and been getting these faults codes consistently ever since...

17831 - Secondary Air Injection System; Bank 1: Insufficient Flow
P1423 - 35-00 - -
17819 - Secondary Air Injection System; Bank 2: Insufficient Flow
P1411 - 35-00 - -
17544 - Fuel Trim: Bank 1 (Add): System too Lean
P1136 - 35-00 - -
Readiness: 0000 0000


Also here is Block 32 are these values anything to be concerned about?

17:26:59 Group 032: Lambda Control (Mixture Adaptation)
7.9 % Adaptation (Idle) Bank 1 Sensor 1
-6.3 % Adaptation (Partial) Bank 1 Sensor 1
6.9 % Adaptation (Idle) Bank 2 Sensor 1
-8.6 % Adaptation (Partial) Bank 2 Sensor 1
