10.1 Replace parts on the refrigerant circuit -
General instructions
• All the components of the refrigerant circuit, which are sent in
for quality monitoring, must always be closed (use original
screw caps of the original part).
• The original parts (AC compressor, catch pan, evaporator,
condensor) were previously filled with nitrogen gas. This filling
of nitrogen gas escapes uniformly, more specifically, the pres‐
sure of the nitrogen filling is now so low that when opening for
the first time, it is no longer noticeable that gas escapes.
• On vehicles with an AC compressor without magnetic cou‐
pling, the engine must only be started if the refrigerant circuit
is correctly assembled, see
⇒ "1.15.3 Additional work on vehicles with AC compressor
without magnetic coupling ", page 15
• So that the AC compressor with the regulating valve for com‐
pressor of air conditioning system - N280- suffers no damage
when the refrigerant circuit is empty, it is fitted with a secured
oil supply. This means that approx. 40 to 50 cm
oil remains in the AC compressor.
Two refrigerant circuit systems are installed:
♦ Refrigerant circuit with throttle and catch pan with integrated
dessicator (Superb l)
♦ Refrigerant circuit with expansion valve and fluid reservoir with
installed dessicator (all types except Superb l)
The catch pan / fluid reservoir / dessicator must not be replaced
under the following conditions:
♦ After an accident, but without any visible damage to the catch
pan / fluid reservoir, and if the refrigerant circuit was not
opened.
♦ The repair (replacement of defective components) is per‐
formed for a short period and no humidity has penetrated
(during the repair the components were immediately closed
with screw caps after separating them in order to avoid any
humidity from penetrating).
