2001 Audi A4 B5 1.8 L Vacuum Hose Leak
 

So I just bought this car about a week and a half ago and it threw a check engine light with the code P0411. I looked into it and it says a Vacuum hose leak and for the life of me I can not find where or if it’s leaking. I was wondering anyone’s thoughts on what it could be if not that or how to find it easier. Thanks
