Thought my air con was a bit poor so got it re-charged but with no change. Took it to the dealer as it's still just under warranty and they diagnosed a leak in the condenser. Apparently they are on back order from Vauxhall - and there is a backlog of 600 units!

I know it can be done at home but I'm going to wait to have it done under warranty - when I have no idea (neither do they).
