Hey guys, you can buy a can of the aircon cleaners at Supercheap, Repco, etc. They're about $12-$15 each and it's the same process as what Honda does (and charges you $50-$80). My mum went to service the Jazz and it had this issue and they charged us $80. Later on my friend who works for a dealer for VW and told me about the can and what they do.
