Sounds like one or both of the valves are leaking (they would have been sealed by the manifold gauge connections during the pressure test)

Well it is all done and dusted and I now have a fully working freezing air con, topped up with anti bacterial treatment for £32.95 :D
Yes it was just a plug it in for an hour (no leak detected, and as we know the machine will not fill up with gas if there is a leak ) scenario but that is all I wanted and expected. I knew the system had a leak in it, in fact it only had 20g in it, but it is a slow leak as the last top up was over two years ago. The operative was not conversant with air con even to the point that he did not know that a leak sealer is available, it is just another job for them.
Anyway I can keep cool for another two years for a nominal fee and will investigate Larry's suggestion for the leak 8-)

another common one is a perforation on the condenser. i have that on one of mine. Its too small for the dye or the pressure test to show up. But the technician who knows his stuff found it with the spray bottle solution, that blows bubbles over a leak took a while to show up. It was well hidden. End result, new condenser needed. He tells lie the no.1 most common leak point is hole sin the condenser. (not on Jags per say but on all the cars he does).
They are not expensive for your late 40 Don. I would consider fitting a new one. It will likely pay for it self in a couple of years. Also fit a new Drier bottle while you are at it.

I have fitted a new condenser and receiver / drier and evaporator within the last 5 years or so.
