Instructions for opening and part exchange in refrigerant circuit (Countryman 2017-2023, except PHEV)
Required Special Tools:
- 00 9 030
- 32 1 270
WARNING:
- Avoid contact with refrigerant and refrigerant oil
- Follow Safety instructions for handling refrigerant. Refer to INSTRUCTIONS FOR HANDLING R1234YF REFRIGERANT (COUNTRYMAN 2017-2023, EXCEPT PHEV) , NOTE FOR HANDLING R134A REFRIGERANT (COUNTRYMAN 2017-2023, EXCEPT PHEV) , NOTES REGARDING REFRIGERANT (R134A, R1234YF) AND REFRIGERANT OIL (COUNTRYMAN 2017-2023, EXCEPT PHEV) , SAFETY INSTRUCTIONS FOR HANDLING REFRIGERANT R1234YF (COUNTRYMAN 2017-2023, EXCEPT PHEV) and SAFETY INSTRUCTIONS FOR HANDLING TETRAFLUORETHANE REFRIGERANT R134A (COUNTRYMAN 2017-2023, EXCEPT PHEV) .
- Follow safety instructions for HANDLING REFRIGERANT OIL .
Attention!
- Always use new O-rings each time A/C connections are opened (refer to applicable BMW parts catalogue)
They must not be coated.
Use special tool 00 9 030 to install sealing rings without damaging them.
- Open the refrigerant circuit for as short of a period as possible.
- Close all components and lines in the refrigerant circuit and return parts immediately following the removals at openings with special tool 32 1 270 to prevent penetration of moisture or foreign objects.
- If the refrigerant circuit was closed at the openings with special tool 32 1 270 but it remains open for more than 24 h, the dryer insert for the air conditioning must be replaced.
- Part replacement as preliminary work fur further repair work and part replacement based on gradual leakage.
(minor leak, e.g. hairline crack)
Procedure:
- Suction heating and air conditioning system, then determine suctioned coolant oil level. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) (COUNTRYMAN 2017-2023, EXCEPT PHEV) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) (COUNTRYMAN 2017-2023, EXCEPT PHEV) .
- Carry out part replacement
- Replace removed refrigerant oil and additionally top up with new refrigerant oil according to components replaced:
- Compressor: refer to NOTES ON COMPRESSOR REPLACEMENT .
- Evaporator: 10 ml
- Air conditioning condenser: 20 ml
- Desiccant insert/dryer flask: 20 ml
- Each replaced refrigerant line: 10 ml
- Air conditioning condenser with integrated dryer flask: 40 ml
- Safety pressure switch and gasket: no additional refrigerant oil
- Only I01: Radiator, high-voltage battery unit: 20 ml
- Evacuate and fill air conditioning system. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) (COUNTRYMAN 2017-2023, EXCEPT PHEV) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) (COUNTRYMAN 2017-2023, EXCEPT PHEV) .
- II. Part replacement due to sudden leakage
(major leak, e.g. pipe break due to accident)
Procedure:
- Suction HEATING AND AIR CONDITIONING SYSTEM , then determine suctioned coolant oil level
- Carry out part replacement
- Replace removed refrigerant oil and additionally top up with new refrigerant oil according to components replaced:
- Compressor: refer to NOTES ON COMPRESSOR REPLACEMENT .
- Evaporator: 35 ml
- Air conditioning condenser: 35 ml
- Desiccant insert/dryer flask: 55 ml
- Each replaced refrigerant line: 35 ml
- Air conditioning condenser with integrated dryer flask: 55 ml
- Safety pressure switch and gasket: no additional refrigerant oil
- Only I01: Radiator, high-voltage battery unit: 35 ml
- Evacuate and fill A/C system. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) (COUNTRYMAN 2017-2023, EXCEPT PHEV) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) (COUNTRYMAN 2017-2023, EXCEPT PHEV) .
