Cat converters can't do their job to burn off emissions till they heat up on cold starts. Hence air is injected by the pump to dilute the mixture during cold starts. The pump runs for 90 sec whereby after the converter is hot enough to continue its job. Most euro cars including VW, Audi, utilize this system. What a pain for those who have to work on these!

To add to the SAI head ache can be the setting of the monitor during warm up. This is what typical inspection stations look for to pass the car. How do I know, I went to inspection 2 months back and low and behold my Evap and SAI monitors were NOT complete. A $1000 later I got the Evap system monitor to complete so I could Pass inspection. I still don't have the SAI setting complete but I do need some more drive cycles to verify if there is a problem.

Thanks for the information guys. I was also able to find an informative u-tube video.

How do I "set the monitor"?

We don't have inspection stations to deal with here in Minnesota yet.

I hoping to pull the unit and disassemble it. Hopefully inspect and grease or replace the bearings. I'll just replace it if it comes down to it.
