YANGCAN LEDVAS Black Storage Tray Dashboard Shelf Set Fit For VW Rabbit Golf GTI Jetta MK5

For my girlfriends 2010 jetta so im not totally farmiliar with the car, but does anyone miss the function of the air flow vent???

If replacing the vent cover with the tray causes the vent switch to be stuck open, does it decrease the air pressure from the front-facing air vents?

Will this fit 2008 vw R32?

Will this work on a 2011 VW Golf?
