Saip problems/questions

I recently replaced my saip and combi valve due to a p0411 code. Just a few days later I am showing this code again. The saip is working but when I feel the hose that goes into the air box it feels as if it is blowing air out. If I recall correctly it is supposed to sucking air in. I have to pass emissions in a month so I'm trying to get this resolved. Anybody know what could be causing this?

Thanks in advance
