I found these in the boot of my Superb estate. I can't find any info on where they are supposed to go? Any ideas? 

In your boot you have a full width hammock for carrying light items. These clips connect onto the rearmost bar of this hammock, with difficulty, to give you two more hooks in the rear boot space.  Once in place though you cannot roll up the hammock to store tidily .  I have mine in the side storage pocket after clipping them on and off a few times. A versatile idea but not too successful.

I hadn't noticed the hammock due to the estate having the automatic powered luggage cover. 😊

 

 

You may need to flip the luggage cover up to see the hammock bar clearly.  Mind your fingernails when you struggle with those clips.
