hello guys. Thanks for the help. I got it resolved but in the hard way. I'm posting it here so someone else would find it helpful.
Actually I went to sta**rd, and they said, there was no gas. Since they does not have R1234-yf gas with them, I went to media*a*r at peliyagoda. They checked the system and said, condenser has leaks and need to be replaced. condenser itself costs around 55k. what they have is Thailand made condenser and there seems to be no other option as agents does not have any of it. Also gas is not cheap either. They quote 65k. Also they said even some other brandnew(since mine is recon from UK) civics came with the same issue, and it seems to be a factory fault/ o(or climate issue). There were no signs of crash or any sort of thing, but condenser had leaks somehow.
