Do you have vag-com? If so, you can just perform an output test

You'll here the secondary air injection pump if it runs....it's kinda like a small jet engine.

Re: Yes, it's working...that's the noise

Itried it today agian i let it sit for 24 hours(to get cold agian).I hear that noise then it goes off after about 15-30 seconds. Thats when the check engine light comes on. I checked all the hoses and piping like the bentley told me too, but thoes codes still come up.The bentley saids its "low flow".Next ill check the sec.air injection solinoid valve(N112). Any other idea's?

I think i found the problem. The right side secondary air injection valve(combination valve), I can blow air by it and the bentley said you souldn't be able to.
