Yes as far as I’m aware they are the right way, it’s supposed to suck air, I just can’t understand how if I pull the pipe off the thing opens then stays open until I turn sport mode off. Also when the car is switched off i can’t move the actuator arm until I pull off the vac pipe it’s like it’s holding a vacuum even when the engine is off. It can’t be the solenoid as that’s new, but the actuator closes when sport mode is turned off. Is the actuator controlled from throttle when driving for example in sport mode when you accelerate you hit say 4500rpm does the flap open?

I would try swapping the hoses round on the solenoid, it sounds like the vacuum is being held in the system which sounds like it’s back to front if you know what I mean. Swapping the hoses is a quick and easy check, if that doesn’t work then I’m stumped as your vacuum pump is working, your valve is working and you have a new solenoid which should be working. At least then you’ve eliminated all the variables you can. Failing that it would have to be a VCDS scan.
No as soon as you press the sport button it should open or close even at idle.
