Cool P0411 Error Code -- Secondary Air Injection System

Hello everyone, I've recently acquired a P0411 secondary air injection system code and have been troubleshooting it. I've researched the problem on the other forums, as well as followed the do it yourself troubleshooting from

The question I have for anyone, is that when I took the injection tube off the control valve on the exhaust manifold, I found clear fluid in the fitting, my guess is water. Is that what has potentially ruined my valve?? I looked up the part number on the valve and noticed is has changed at some point?? Possibly a new revision that works better than the original?? No warranty on that BMW?? or recall. Thanks alot. Getting ready to dump the Bimmer for a Bemmer if repairs continue draining my bank account.

Any ideas out there on the subject??
