Secondary air is for quicker catalytic converter start up. First, do you know how to fix cars? If yes then repost to me and I will try to help you. If no then you should seek local professional help.

Yes, I do know how to repair cars. I saw in other BMw forum the purpose for the secondary air system. I did a visual check and the hoses seemed be okay from the Secondary air pump. What steps do you recommend?

Replace the secondary air pump.
