Every year for the last five years my 993 C4 looses most of its R134a refrigerant by early summer.
Every year my local air con guy vacs out he remaining refrigerant. carries out a nitrogen pressure test and a visual test for the green dye and finds nothing.
So we refill it and try again for the same thing to happen next year.
Whilst the testing is taking place the "connectors" are being utilized. This and a hint of green dye in the connector cap lead me to try changing the connectors.
With my air con guy giving up the work (I thought £30 for a re-gas was very reasonable) it was off to Kwik Fit (£49) and their automatic machine.
0.145 of refrigerant recovered -meaning I had lost nearly 700g of the stuff in a year. Vacuum test once again showed no leaks so I fitted the new connectors and look what I found when I examined the old ones.
It will be another year until I know if I have found the problem
These are the parts that I am calling connectors
Note how the valve is offset
Valve disassembled and "legs" tweaked
"valve" reassembled and now central
