So I have the check engine light on and I had the dealer diagnose it, and what they told me the problem was, was the secondary air pump check valve. I tried to have the guy explain it, but only being a service rep he had no clue. I only have a slight clue, so I am here to ask you guys. I'm not sure what this is, or how to fix it. If I am not mistaken this shows the secondary air pump; http://www.realoem.com/bmw/showparts.do?model=AV33&mospid=47720&btnr=11_2203&hg=11&fg=45
I also know from replacing the valve cover that when I was in there I saw the hose (part #3 on that page) is broken. So could this be my problem? Also what effect does it have on the engine?
