Is Load guard standard equipment?

[Notajock]

In the C6 Allroad I just bought, there is no retractable net load guard, even though the manual does not list this as * or as an accessory. I had one in my C5 Allroad, and really miss it. Nor can I find it as an Audi Accessory, even though here are mounting slots for it on the back of the rear seats.

1. Should there be one as standard? 

2. Would the one for the C5 Allroad fit onto the rear seats of the C6? 

Local Audi dealer rather unhelpful or lack knowledge. 

Thanks for your help.
