What codes are on this time? The same ones? What did you replace? The SAI pump itself?
The second code is for an O2 sensor most likely, or the cat. So you'll need to troubleshoot that.

HELP..... I have a 2000 Jetta with a 2.0 The check engine light came on which resulted in code 04-11 and 04-22. I made the mistake of replacing it with an after market and ended with the same results. I got another O.E.M one and put it in. Was fine for 2 days and check engine light just came on again.
Could it be something else I am missing???
Any help would be appreciated. Thx

an o2 would not cause a sec air fault, check the combi valve, sec air soleniod or vac hose

Most of my previous SAI codes were resolved with a new vacuum line.
