Air conditioning system with refrigerant R134a - Edition 10.2014
The catch pan / fluid reservoir / dessicator must be replaced under
the following conditions:
Note
On vehicles with expansion valve the dessicator is arranged
♦
as a separate component and thus the reservoir must not be
completely replaced yet, only the dessicator, see ⇒ Heating,
Air Conditioning; Rep. gr. 87 and ⇒ Electronic Catalogue of
Original Parts .
The new generation of fluid reservoirs is directly installed on
♦
the condensor and is therefore inseparably connected to it.
• The refrigerant circuit has been opened as of an undetermined
time (creeping leakage).
• The repair extends beyond the normal repair time and humid‐
ity has penetrated.
• The refrigerant circuit was blown through with compressed air
and nitrogen or was flushed with refrigerant R134a.
• The AC compressor has blocked (inner damage).
• The catch pan / fluid reservoir is damaged (accident).
10.2 Components of the refrigerant circuit
leaking or damaged - the refrigerant cir‐
cuit is absolutely empty
Note
If it is only a minor leakage and the refrigerant has creepingly
♦
escaped, the loss of the refrigerant oil and the penetration of
humidity have nearly no influence on the function of the air
conditioning system.
♦ Only carry out the work steps marked with an * for major leaks
(e.g. after an accident).
– Remove the defective component and replace it.
– Remove the A/C compressor. *
– If dirt penetrated into the AC compressor when the refrigerant
circuit was opened (e.g. during an accident), the AC compres‐
sor must be replaced.*
– Remove the oil drain plug from the AC compressor (replace
O-ring ⇒ Electronic Catalogue of Original Parts ) and drain oil.
In order to speed up the evacuation of the refrigerant oil, turn
the AC compressor with the clutch disk of the magnetic cou‐
pling by hand (disposal of used oil
⇒ "3 Legal texts and legal regulations", page 33
– Subsequently fill new refrigerant oil into the AC compressor (if
it is not replaced). The oil quantity and the oil type correspond
to the refrigerant oil volume in the new AC compressor, see ⇒
Heating, Air Conditioning; Rep. gr. 87 .*
– Flush the refrigerant circuit with the refrigerant R134a, if this
is not possible, blow through with compressed air and then
with nitrogen

– Replace catch pan and throttle/fluid reservoir with dessicator
(or only dessicator, specifically designed for vehicles)
