1 Fault Found:
00716 - Air recirculation Flap Positioning Motor (V113)

Any help would be great.

Thanks.

First off disconnecting the battery does not fix any problem the car has. It just makes the check engine light go out until the car runs the monitors again & discovers the problem again.
What are the complaints that you are trying to resolve?
From what i see you have a problem with the secondary air injection system that will make the check engine light go on , other than that do not look for problem unless you have a complaint!

seems like you have a vacuum leak on the control side of secondary air system

Thanks for that, all i need to know.
