Volkswagen Golf Service & Repair Manual: Detecting leaks
External damage can cause leaks in the refrigerant circuit. Because a small leak will involve only small quantities of refrigerant, leaks should be checked for using an electronic leak detector or by introducing a leak detection additive to the refrigerant circuit. Electronic leak detectors can detect leakage rates of less than 5 grams loss of refrigerant per year. The leak detector should be specific to the composition of the particular refrigerant in use. For example, a leak detector for R12 refrigerant is not appropriate for R134a refrigerant because R134a refrigerant has no chlorine atoms to which the lead detector responds.)

There must be space both for liquid and vapour in a
container. As the temperature rises, the liquid expands. The
space occupied by the vapour becomes smaller. Eventua ...
