BMW rough idle? | high fuel consumption? Vacuum hoses replacement & control valve removal

Since a while I was suspecting some vacuum leaks on my BMW 320i with an M54 engine. I did a diagnose but there were no faulty codes at all. May be because the leaks were too small so they are not causing the troubleshoot codes to popup.
But anyway, I decided, without a previous check with a smoke test or whatever, to change the hoses on some of the vacuum lines:
The vacuum line of the fuel pressure regulator
The Vacuum line of the secondary air valve
The vacuum line of the vacuum control valve behind the intake manifold.

For this purpose I draw a sketch to highlight the main vacuum lines on a M54 engine. To make my life easier while commenting this video I'm using colors to tag the hoses that I'm working on.

I was about removing the intake manifold to refresh the lines but I decided to give it a shot and try to remove the control valve without removing the intake manifold.
The operation ended successfully and saved a lot of time.
