a/c

Hi there, Wasn't sure if this is the correct section but i'm sure a mod will move it if so! I'll try cut a long story short! Went to get my A/C re-gassed the other day due to the scorching weather to be told there was already gas in the system to which i thought to myself 'oh it must be low...

Hey guys, recently purchased a DC5R and I saw today that in the engine bay the hose that connects to some sort of A/C unit is just free and unattached to anything. What must i buy to get the A/C running, it is AUS spec so i think they are meant to come on the car. Thank you in advance
