Volkswagen Golf Service & Repair Manual: Searching for leaks in refrigerant circuits using leak detector -V.A.G 1796
 Note
| Small leaks can be detected with, for example, an electronic
leak detector. |
| – |
Evacuate refrigerant circuit using an air conditioner
service station
→ Chapter. |
Note
| If a larger leak is detected during the evacuation process,
determine cause and rectify as described
→ Chapter. |
| If during the evacuation process no leak is detected or a
very small leak is detected that but cannot be located, proceed
as follows
→ Chapter. |
| 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). |
| – |
Prepare leak detector for operation according to its
operating instructions. |
| – |
Always hold probe tip under location of suspected leak. |
|
|
|
| If the rate of clicks rises or a howl occurs, depending on
model, a leak has been found (see operating instructions for
leak detector). |
