[BiturboS4] A plastic flap... but what does it do?

[Andy Turner]

After having my S4 for 8 months or so, I finally noticed that there's
a little flap that comes down and doesn't appear to do a great deal.
It's close to the rear view mirror, next to the two little red LEDs
that shine down onto the gearknob area. What's it for? The only thing
I can think of is an attempt to block out the sun from the little gap
you get when both sun visors are down, but if that's it, then it's a
pretty poor effort that would only really work if you were sat in the
middle of the car, not in either seat!

Any idea?
