A5 convertible part name

[Gary 78]

Hi good evening all, I was wondering if anyone could help me I've just bought my first A5 cab and there's a little post missing that's driving my OCD mad ha ha. 

So on the top of the dash near the windscreen in between the vents there is a little square bit , mines missing it does look like there is some sort of metal bit on either side of it, it's only small about 2 inches wide, but I can see it reflecting through my windscreen, does anyone know what it is or what it's called, can send a picture of required, thanks all

Welcome Gary, 

Whatever it’s called, it will be a main dealer only part, so best nip it along to your nearest and ask the Parts chap to order you one. 
Kind regards,

Gareth.
