Note
In the Golf Hybrid 2014, the refrigerant circuit is flushed in 2 cy‐
cles. For the first cycle, the adapter for the shut-off valve -N541-
is open, and the adapter for shut-off valve -N542- is closed. This
will cause the refrigerant circuit with the evaporator in the heater
and air conditioning unit to be flushed. For the second cycle, the
adapter for the shut-off valve -N541- is closed, and the adapter
for shut-off valve -N542- is open. This will cause the refrigerant
circuit with the evaporator in the heat exchanger for high-voltage
battery to be flushed ⇒ Heating, air conditioning; Rep. Gr. 87;

manual for the specific vehicle).
Note
The illustration shows a refrigerant line -A- with a permanently
♦
installed restrictor -B- (without strainer). This refrigerant line
must be drilled open with a suitable 5 mm drill bit (remove the
restrictor if it is removable), and it must be cleaned before it is
installed in the purging circuit. Renew the refrigerant line which
has been drilled open after purging has been completed ⇒
Electronic Parts Catalogue .
The diameter of the shown restrictor hole -B- is
♦
approx. 0.7 mm. Depending on the refrigerant line version, this
restrictor is permanently installed or it can be removed. For the
removable version a strainer may be fitted to prevent the re‐
strictor hole from being blocked by suspended particles.
