Hi looking for some help with an engine management light fault.

There is two fault codes coming up which are as follows:

17831 - Secondary air injection system; Bank 1
P1423. - 002 Insufficient Flow - MIL ON
17819 - Secondary air injection system; Bank 2
P1411. - 002 Insufficient Flow - MIL ON

Any help with what is causing this would be greatly appreciated, the engine appears to be running okay, but engine management fault light on with the above codes from VCDS

Sounds like the electric SAI pump. Probably full of water. Open it up and have a look.
