sunroof deflector

[silversprings]

When we bought our premium used '05 530, the sunroof required a part and some work to get it to operate - all under warranty.

What I have noticed however, is in the full open position, there is no popup deflector to baffle the vacuum sound created by sunroofs.
Does anyone know if this car should have one of the popup deflectors - I am thinking they forgot to reinstall it.

When I have the sunroof open, I always have to open a window a slight bit to counter the suction noise.

have been looking at others and always see some sort of deflector.
My old 530 had a spring loaded popup deflector.
thought I would post first before going back to dealership.

Thanks

Update,
Took it to the dealership - they conceded to the fact that they overlooked that part when working on the sunroof at purchase. They neglected to put back the deflector. They ordered a new one, installed it and now it's great.
Why does it take my diligence to spot something they did wrong.
