Note
♦ If repeated check results in air conditioning system still not
operating correctly, purge (clean) the refrigerant circuit
⇒ page 67 . Then renew the air conditioner compressor and
receiver.
♦ In this case, the evaporator may ice up although the correct
quantity of refrigerant is present in the refrigerant circuit.
Possible deviation from specification Possible cause of fault Rectifying fault
• High-pressure and low-pressure
are normal,
• The required cooling output is not
delivered.
Too much refrigerant oil in circuit. – Drain refrigerant cir‐
cuit.
– Purge (clean) refrig‐
erant circuit
⇒ page 67 .
• High-pressure and low-pressure
are normal,
• The air conditioner compressor is
noisy (especially immediately af‐
ter being switched on),
• The cooling power required is de‐
livered.
Note
♦ Overfilling with refrigerant oil can occur if the refrigerant oil
level was not checked after the air conditioner compressor
was renewed.
♦ If the air conditioner compressor is not to be replaced, drain
refrigerant oil from air conditioner compressor via the drain
plug. From the total amount of refrigerant oil, fill 50 g direct into
air conditioner compressor and fill remainder in refrigerant cir‐
cuit according to ⇒ vehicle-specific workshop manual .
10.4 Checking systems with an expansion
valve and reservoir (without regulated
air conditioner compressor)
10.4.1 Test prerequisites
• Radiator and condenser must be clean (clean them if neces‐
sary).
• The V-belt for air conditioner compressor and alternator is
correctly tensioned.
• All air ducts, covers and seals are OK and properly installed.
• The flaps reach their end positions.
• The engine is at operating temperature.
• The evaporator and heating do not draw any uncooled air at
highest fresh air blower speed.
