Have finally figured out that this is what has been fitted to my leon since I got it. Have figured out how to close it off so its not doing anything now.
Will it do anything to my car, detrimental or otherwise?

An ecotec valve, or a powertec valve? 2 different things. Is it one of those things that supposedly save you fuel?
