6.3 Detecting leaks in refrigerant circuit us‐
ing leak detecting system - VAS 6196-
or leak detecting system - VAS 6201- or
a later model
Note
Small leaks can be detected with, for example, an UV leak de‐
tector additive.
– Evacuate refrigerant circuit using an air conditioner service
station ⇒ page 50 .
Note
If a larger leak is detected during the evacuation process, de‐
♦
termine cause and rectify as described
If during the evacuation process no leak is detected or a very
♦
small leak is detected that but cannot be located, proceed as
follows ⇒ page 56 .
Refrigerant gas is quickly dispersed by air motion. Therefore
♦
drafts must be avoided during a search for leaks.
If the refrigerant circuit is completely empty, charge with about
♦
10% of refrigerant capacity (sticker R134a or vehicle-specific
workshop manual).
