Had car back from kwick fit were the re gased the system. After refilling three times they found the leak which they said to be coming from the seal which are a main dealer part? Spoke to local VW dealer who advised they don't supply seals themselves just parts that will include the seals.
Now, any thoughts what these seals are leaving out the gases and any recommendations of a good air con fixer in Swansea area south Wales? Any thoughts welcome
