I tried to have the air con regassed and have been told by 2 garages, (halfords and our local independent), that the condenser radiator has a hole in it. I am looking at renewing this myself and then getting it regassed at a local garage. I have seen that the system needs oil in it, but have no idea what type, can any point me in the right direction and suggest how much I put in? Also has anyone done this themselves? If so any pointers? Thanks
