Detecting Leaks On The Refrigerant Circuit With The Leak Detector Vag1796; Detecting Leaks On The Refrigerant Circuit With The Leak Detector Vas 6196 Or Vas 6201A - Skoda Citigo 2012 Workshop Manual

– If a minor leak is suspected (according to the vacuum test),
subsequently carry out a leak check using the leak detector -

detector VAG1796 ", page 45
tion system - VAS 6196-
⇒ "6.4 Detecting leaks on the refrigerant circuit with the leak
detector VAS 6196 or VAS 6201A ", page 45
– The refrigerant circuit can only be filled once the leak check
has been performed successfully.
6.3 Detecting leaks on the refrigerant circuit
with the leak detector - VAG1796-
Minor leaks can be detected for example with an electronic leak
detector or with an UV lamp.
Note
Refrigerant gas quickly floats away with the movement of the
♦
air. Therefore avoid any draught during leak detection.
If the refrigerant circuit is absolutely empty, fill in approx. 100
♦
grams of refrigerant.
Leak detection:
– Operate the leak detector according to the relevant operating
instructions.
– Always hold the test prod below the suspected leakage.
If the knocking noises increase or a whining tone occurs as a re‐
sult of the design, the leak point has been found (see operating
instructions belonging to the leak detector).
6.4 Detecting leaks on the refrigerant circuit
with the leak detector - VAS 6196- or -
VAS 6201A-
Minor leaks can be made visible with the fluorescent leak detec‐
tion additive - VAS 6196/1- which is added to the refrigerant
circuit.
