A8 rear dual climate zone.
 

hey all,

newbie here and a proud owner of 2006 audi a8 L (fully loaded). the rear has seperate dual climate zone which used to work (if someone sitting in the back changes the temp etc for each side it would work independently) i dont know what i did from the front climate zone that everything is controlled from the front. when i try to change the temp or press any button on the rear climate zone (both sides) it says "PAS SIU" or "PAS SIV" any help would be good to keep the front and back totally independent of each other.

p.s. lost the manual (was moving houses and it was a big mess..thats a whole diff story) btw im from toronto canada....
